In dentistry, a wisdom tooth is called a “figure eight.” The laying of eights occurs at the age of three, and it is then that their number is determined. But they take quite a long time to form, some people may have all 4, but many people have 1-2 eights in their entire life. At what age and how long does a wisdom tooth grow?
Features of wisdom teeth
Over the course of evolution, the human jaw decreased in size as food became softer and easier to chew. Accordingly, the number of teeth was reduced to 32, which is quite enough for modern food. Some doctors consider figure eights to be rudiments, but with normal eruption and the absence of complications, they fully perform their functions.
The structure of eights differs from the structure of other teeth by their root system. It can have up to five roots, most often their number is 2-3. Sometimes they grow together into one massive root. The roots of figure eights are often very curved, which prevents their normal healing process.
Some doctors consider wisdom teeth to be rudiments (this is a part of the body that, in the process of evolution, has lost its functional purpose), but they can play important role in old age, becoming a support for a bridge. In addition, they can take on most of the load during chewing if the adjacent tooth had to be removed for some reason.
If they are healthy and positioned correctly, they are an excellent addition to the dentition. Unfortunately, eights often cause trouble: they have trouble erupting, quickly deteriorate and have to be removed.
When does it start to grow?
At what age does a wisdom tooth grow? For most people, it begins to erupt at the age of 17-22 years, but this can happen much later - at 30-40 years. Nature has provided 4 eights for each person, but for some people they do not appear at all. Often only two eights erupt, while an x-ray shows that the rudiments of the rest are absent.
Their number depends on several factors:
- heredity,
- number of primordia,
- shape, size, anatomical features of the jaws.
How long does it take for a wisdom tooth to grow? It is interesting that it takes a very long time to erupt - sometimes for decades, periods of growth are replaced by periods of rest. By the time all of the child’s teeth have erupted, the crown part of the number eight is just beginning to form. After eruption, its roots continue to form for another three to four years. Not every stage of teething is accompanied by pain. The most unpleasant moment is the moment of teething itself. This is due to the fact that the eight does not have predecessors, like all other teeth, so it has to make its way through the already formed bone. Even if a person has formed all 4 rudiments, this does not guarantee that they will all erupt in their places.
Very often you can find an impacted wisdom tooth in dental practice - this is one that has formed, but has not fully erupted. It is partially or completely covered by the gum mucosa. Such teeth must be observed for inflammatory processes and location in the oral cavity.
Despite the fact that the impacted eight is under soft tissues, it can push neighboring teeth, cause pain and increase the risk of caries.
In what cases is it necessary to delete?
The picture shows the beginnings of four wisdom teeth
In most cases, wisdom teeth are long and problematic, causing pain and discomfort. The most common complications that arise during their occurrence are:
- Inflammation of the tissues that surround the tooth often develops. When it begins to erupt, a mound forms above it, which is covered with mucous.
This tubercle is called the hood, which in the process of chewing food is regularly irritated, as a result of which the mucous membrane is injured, and then infection occurs. As a result, inflammation of the gums begins, which is called pericoronitis.
The main symptoms of pericoronitis:
- Pain in the area of the wisdom tooth, which gradually increases.
- Pain often radiates to the temple, ear, and the throat may hurt.
- The lymph nodes in the neck area often become inflamed.
- The temperature may rise and general weakness may occur.
- The gums swell, turn red, and hurt when pressed.
- Pus may ooze from the gums.
Pericoronitis is a very unpleasant phenomenon that causes a lot of inconvenience. It often gets to the point where it becomes difficult to speak and open your mouth. It is impossible to cope with the disease at home; you need to consult a specialist.
Treatment consists of opening the hood, after which it is washed from pus, food debris, and treated antiseptics. Antibiotics are often prescribed after such manipulation.
- Malocclusion
Often there is not enough room for growth, so the figure eight props up and displaces the adjacent tooth, which begins to move all the others. As a result, the entire row becomes bent and malocclusions develop.
- Inflammation of the trigeminal nerve
- Jaw cyst
A wisdom tooth is an ordinary multi-rooted tooth, like others. Dentists call such teeth “eights,” because if you draw a vertical line dividing the right and left sides of the face, then the wisdom teeth will be the eighth teeth. How many wisdom teeth does a person have? There is no standard for their quantity. Nature has endowed each person with two pairs of “eights”, two teeth per jaw. But the fact is that in the process of evolution, the human jaw has undergone changes and has become slightly smaller (1 cm) than that of our ancestors. This is due to the transition to softer and thermally processed foods, which reduced the load on the jaw.
And in our time there are not four, but fewer, for some people they may not exist at all. This is due, in particular, to the work of hereditary memory. If immediate relatives suffered from diseases during the eruption of “eights”, and the treatment was radical, then in subsequent generations the rudiments may not form. This is confirmed by frequent cases in which a row contains only one erupted “eight”, and radiographic data demonstrate the absence of even the rudiments of a “twin”. Whether or not a person’s “eights” will grow, how many of them there will be, how they will be located, depends on the following factors:
- From heredity,
- From the number of primordia,
- From the shape and size of the jaws.
When can I expect my wisdom teeth to erupt?
The process of changing from dairy to permanent ones occurs in the interval from 6 to 13 years. Wisdom teeth take several decades to form, alternating between stages of development and rest. By the age of three, the rudiments of all radicals are formed, it is at this time that it is determined how many rudiments of the “eights” are laid and whether at least one will grow. How long does it take for a wisdom tooth to grow? By the age of twelve, all natives already take part in chewing food, and the “eight” is at the stage of completing the formation of the crown.
At what age should I wait for the “eights” to appear? They usually erupt by age 22. Usually, if wisdom teeth have not grown in by the age of 27, then you can’t wait for them. The cutting time depends on the size of the jaw and the location for its location. The cutting process under favorable conditions takes an average of one and a half months. The roots continue to form for 4 years after eruption.
Why do the “eights” have such a name? The age of wisdom teeth eruption is characterized by formed and developed organs and systems of the body; from this period the aging of the body begins. Wisdom teeth appear during the period of maturity of the body, hence their name.
Is there a need for such teeth?
As is known, there is nothing superfluous in nature. Although wisdom teeth have lost their function during evolution, they can still be beneficial in old age. If the owner loses the seventh tooth, then the wisdom teeth can partially take over the chewing function, and can also be useful in bridge prosthetics, becoming a support.
If the "eights" are healthy and correctly positioned, then they can be an excellent addition to the dentition, but in most cases they are the source of problems. There are many complications associated with their eruption.
Complications of eruption
Most common tissue inflammation, surrounding the tooth. The growth of a wisdom tooth is accompanied by the appearance of a tubercle from the gum mucosa. This shell is called “Hood”. The “eight”, covered with such a “hood”, experiences pressure and is injured by solid food, this facilitates the attachment of bacteria, causing inflammation. If food gets under the “hood”, then favorable conditions arise for bacteria, which, in turn, carries the risk of pericoronitis, i.e. purulent inflammation.
Manifestations of pericoronitis
In the area of a growing wisdom tooth the pain begins to increase. It is very noticeable and can radiate to the temple and ear. Pain may occur when yawning, swallowing and opening the mouth. It may seem that your throat or cheek hurts, not your wisdom tooth. Facial muscles and The lymph nodes. Inflammation of the "eight" can affect the entire body as a whole, which reacts high temperature, headache. The gum area swells, the mucous membrane is red and painful, and when pressed, pus is released from under the “hood.”
What is prohibited to do
- To prevent the spread of infection, do not apply heat to your cheek or rinse your mouth with warm water. Otherwise, suppuration of the bone tissue may occur.
- There is no need to put painkillers on the area of the inflamed gum, as you will not be able to relieve the pain, and an ulcer will appear in this place.
- Under no circumstances should you listen to the advice of relatives and friends; maybe something helped them, but without an accurate diagnosis and the causes of wisdom tooth inflammation, you should not risk your health.
What do we have to do?
- First you need to visit a dental surgeon.
- Before this, it is possible to take painkillers orally (ketorol, analgin, etc.).
- You need to make a cold solution and rinse your mouth with it. (Put 1 teaspoon of salt and 1 teaspoon of soda into a glass of water).
Doctor treats this pathology opening the “hood”, washing the cavity and prescribing painkillers and anti-inflammatory drugs. Antibiotics are prescribed for large amounts of pus. If the gums become inflamed a second time, then this time the removal of the “eight” is indicated.
Caries. When a wisdom tooth appears, it caries is often observed. The disease develops from insufficient hygiene this site, because the location is difficult to access. Often appear with already damaged enamel and initial signs diseases. "Eights" are often located close to adjacent teeth, which is why caries can spread to them. Therefore, the dentist must decide whether treatment or removal is the best option.
Malocclusion. Very often there is not enough space in the jaw and the outer teeth begin to put pressure on the “sevens”, which, in turn, support the “sixes”, a chain reaction occurs, ultimately, in the center of the jaw there is crowding of the front teeth and a violation of their correct location. An abnormal bite develops.
Pressure on the "seven". The growth of the "eight" sometimes accompanied by dull ache
, which can occur periodically or be constant. It often radiates to the ear, temple or jaw. If not external manifestations such as swollen gums or redness, you need to take a photo. This event will allow you to see the direction of growth and make a decision on whether to remove it or leave it.
Inflammation of the branches of the trigeminal nerve manifested by muscle twitching and pain syndromes in the facial area. They are provoked by daily hygiene activities, for example, brushing teeth, shaving, washing. The manifestations go away with tooth extraction and proper anti-inflammatory treatment.
Jaw cyst."Eight" grows very slowly, which is why it can be a source of education in lower jaw cysts. If its progression is not observed, then the disease is asymptomatic, and its presence is detected during an X-ray of the jaw for other reasons. The growth of the cyst leads to pain in the gum area. Fluid often accumulates in the cyst, which corrodes the walls of the tooth. If an infection gets into the cyst, a flux (abscess) develops. In this case, the “eight” is removed.
Tissue injury. If a wisdom tooth grows incorrectly, for example, in the cheek, it is constantly injures this area during chewing. This can lead to ulcers. If it does heal, it leads to the formation of scars, which are again injured by incorrectly positioned “eights”. This traumatic process can lead to the development of a tumor at the site of the ulcer. In this case, the “eights” are usually subject to removal.
Instructions
Wisdom teeth grow outermost in the gum, i.e. behind the second molars (typical “sevens”) and are called third molars or “eights.” Such a distant location determines their secondary role in grinding food. The main set of teeth necessary for chewing food is 28 teeth, so “eights” are considered “excessive luxury” and are called wisdom teeth.
Wisdom teeth are formed when the last milk teeth are replaced by molars, i.e. at about 13-15 years old. However, they take quite a long time to form and begin to erupt only after 20 years. This long time their complete formation is due physiological characteristics body, because when teething baby teeth, children scratch their gums, bite toys and thereby increase blood flow and metabolic processes that help faster teeth to form. And the third molars are so far away that when chewing, food falls on the first and second molars, and the gums above the “eights” are poorly supplied with blood and are not “massaged” during chewing, which prolongs the process of tooth formation.
Wisdom teeth usually grow in stages. You may experience gum discomfort and sometimes pain for 1-2 weeks, and then all signs of tooth growth subside for several weeks or even months. The growth of “eights” is influenced by hormonal surges in the body; for example, it has been noted that during pregnancy the growth of wisdom teeth is greatly activated. Can trigger growth last teeth pronounced inflammatory processes in the body, which are accompanied by a prolonged increase in temperature.
According to the observations of dentists, the third molars in some people take decades to grow, so if at the age of 20-22 you showed signs of growing “eights”, this does not mean that you will soon have 30-32 teeth. Wisdom teeth often have a paired pattern of growth, i.e. If the upper third molar on the right has come out, then soon expect the same tooth on the left.
The long eruption of wisdom teeth is also due to the fact that they often have an incorrect location, i.e. can be laid at an angle and, when growing, rest against the “seven”. Of course, it is almost impossible for a tooth located parallel to the gum to erupt, so it gradually turns over. This time may take several years, i.e. - if a tooth begins to erupt at the age of 21, the full formation of its location will end by about 30 years.
The process of teething is complicated by inflammation of the gums above the wisdom tooth. If it has at least erupted small part tooth, a focus of infection is formed, into which food fibers and microbes enter, and this place is difficult to access for cleaning. When the gums become inflamed, they become loose and often “pockets” form in them - additional easily infected areas. The surgeon cuts off the “pockets” above the erupting wisdom tooth, thereby facilitating the eruption of the tooth.
If by the age of 27-30 you have never had any signs of the formation and eruption of third molars, then the chances of these teeth appearing after 30 years are negligible, because All formation processes in the body subside by this age, and teeth are no exception.
There are 32 teeth in both jaws of an adult. Teeth wisdom- the last in each row, they erupt later than the others. Thanks to this feature, they got their name, although they have nothing to do with intelligence or wisdom. In dental parlance, these are called third molars.
According to the structure of the teeth wisdom They are no different from the others: they have a root, neck and crown covered with enamel. But they have several peculiar features. Firstly, they do not have milk precursors; secondly, they do not always erupt. Normally, they should grow in a person between the ages of 17 and 30, but in reality this may happen much later or not happen at all. Many thousands of years ago, teeth wisdom occupied a worthy place in the dentition of the human jaw, which was then slightly larger, since the ancestors of people ate tougher foods and had a massive jaw. There were no problems with these teeth. But gradually humanity switched to soft food that did not need to be chewed so thoroughly. In addition, the brain enlarged, which affected the structure and maxillofacial apparatus. The third molars began to cease to participate in the act of chewing and became rudimentary, continuing to grow in the jaw, in which there was much less space for them. So with teething wisdom many people have problems. Since they grow late, in conditions of lack of space, and overcoming a mechanical obstacle, they cause painful sensations. In addition, their growth is often accompanied by various complications, for example, the third molar may take an incorrect position in the jaw and lie horizontally or at an angle. As the lower teeth grow, they sometimes touch nerves or destroy their neighbors; they grow towards the cheek or tongue, causing inflammation and pain. IN Lately cases of missing tooth buds are becoming more frequent wisdom, which confirms the opinion about the vestigial nature of the third molars. Although in other people these teeth grow without problems and are fully functional. Scientists still cannot say
The extreme bone organs in dentistry are called the “figure eight”. Their laying occurs at the age of three years, at this time it is determined what their number will be. Formation takes a long time, some people have all 4 teeth, and many may have only 1-2. How long does a “wise” tooth grow and how does it happen?
How wisdom teeth erupt
Located on both sides at the end of the bottom and upper jaw, serve to assist in the process of grinding food. Like all paired bone organs, they fit symmetrically to each other. They were called eights because they are the eighth in a row relative to the middle incisor. No matter how many molars grow, they are rarely located on the bone in correct position. More often than not, molars develop or erupt with some kind of problem or complication. This is expressed in the wrong direction of growth or location, which sometimes cannot be done without the help of a dentist.
At what age do eighth teeth grow? They begin to climb differently for everyone, but at any age the body, especially in adults, reacts to the process painfully. Often, the extreme molars “push” neighboring bone organs, causing their abnormal growth or inflammation. Reasons why it is better to remove the extreme molar:
- elevated body temperature lasts more than 2-3 days;
- the inflammatory process of the entire dentition has begun;
- bother severe pain, swelling of the gums has appeared, making it difficult to eat food.
The extreme molars have the same appearance as many other multi-rooted bone organs. However, the structure of the eights still has certain differences. This applies to the part that is hidden in the gum. Eights have four or five roots, but there are only one or two, as a result of the fusion of several roots into one. Figure 8 root canals are curved, making them difficult to remove or treat.
At what age do wisdom teeth grow in?
It is impossible to give an unambiguous and clear answer to this question. The number eight grows from a couple of months to decades, causing pain and other inconveniences. Every person has the rudiments of extreme molars, but this does not mean that they will necessarily grow even in old age - it is difficult for them to erupt due to the peculiar structure of the jaw, so they can completely life period remain in the embryonic stage.
When does a wisdom tooth start to grow?
For most of the human population, the number eight grows already from the age of 17, but the process can take a long time and begin at the age of 22. Some people may notice their outermost bones cutting out much later, in their 30s or 40s. Each person should have 4 eights, but they may not appear at all. Often only two of them grow, and even X-ray shows that there are no more rudiments. The number of extreme bone organs depends on the following reasons:
- heredity;
- number of bone buds;
- anatomical features of the jaw, its shape.
Until what age do wisdom teeth grow?
The answer is interesting - there have been cases when the outer molars could erupt over several decades, and during this time periods of growth and rest alternated. Their coronal part is just beginning to form when the child’s remaining bone organs have already all erupted. Even after the figure eight has emerged, its roots are still forming, which may take another three to four years.
Dentists call wisdom teeth “eights.” They grow differently for everyone: some cause pain and complications, while others do not. When do they grow?
Wisdom teeth are formed in the body at 3 years of age. During this same period, their number is determined. It can take a long time to fully develop.
- They can emerge at the age of 17-22.
- They can begin to grow at 25-30 years of age.
- Their growth begins at 30-40 years.
- They may not grow at all.
According to the laws of nature, all 4 wisdom teeth are formed in the human body, but in one category of people, 2, 3 or all 4 of them can come out, and sometimes none grow at all.
What determines the number of “eights”:
- from heredity;
- on the number of primordia;
- sizes, shapes and anatomical features of the jaw.
Growth process
- Tooth formation. The process starts from the 3rd summer age, and ends at 14-16 years old.
- The process of forming the G8 could take up to 25 years.
- The speed of teething varies from person to person and depends on the structure of their jaw.
- First it is formed.
- Then the root of the tooth.
- The process itself.
- The gums begin to swell and itching appears.
- After some time, the tip of the tooth appears.
- After an indefinite period of time, it grows completely.
How long does it take to grow?
- “Eights” are interesting because they can erupt over several years.
- Intensive growth may be replaced by periods of rest.
- If we compare the growth of teeth in a child and in an adult’s wisdom teeth, then when all the tooth processes erupt in a baby, then in an adult only a “figure eight” crown will form.
- It may take 3-4 years for the roots to grow.
- There are still a few years left to create the shoot.
- Even after the dental process is fully formed, it may take several years for it to begin to erupt.
- The “eight” also takes a very long time to erupt – from several weeks to several months.
Symptoms
- Appear painful sensations– in rare cases, they can cause a person to lose consciousness.
- Body temperature may rise to 40 degrees.
- Cheeks, gums or tongue swell.
- Inflamed bone jaws.
- At the site of tooth eruption, inflammation begins with purulent discharge.
- Bone tissue is destroyed under the influence of painful bacteria.
- The gums around the “eight” area become inflamed.
- Foci of inflammatory processes appear on the buccal mucosa.
- May be involved in the process of teething.
- Lymph nodes often become inflamed.
- Pustules form.
- Fever appears.
How to alleviate teething symptoms?
- Contact your dentist for help. If the tooth gets into the so-called “hood”, it will cut a hole in it, then the “eight” will come out faster. But this procedure can only be done when the wisdom tooth is positioned correctly.
- Various analgesics will help reduce pain. You should not apply them to your gums; they can cause ulcers. Analgesics are taken orally and washed down with plenty of water.
- You cannot categorically warm your gums or cheek. Inflammatory processes are activated and accelerated. They can affect nearby tissues and gums.
- You can rinse your mouth with antiseptic compounds. The most common remedy is salt and soda. You need to dilute 0.5 teaspoon in a glass of warm water and rinse with the resulting mixture. oral cavity as needed. If done regularly, it will reduce the risk of bacteria and germs.
- You can lubricate your gums with painkillers dental gels.
- If the doctor deems it necessary, the tooth can be removed.
Possible problems
- Inflammatory processes - aching pain appears first. It may intensify depending on the location of the wisdom tooth and the severity of the inflammatory processes. Inflammation can cause swelling of the gums or cheeks. Then it will become painful for the person to swallow and open his mouth. In these cases, you need to urgently seek help from a dentist.
- Crowded teeth– it happens that wisdom teeth can crowd out other teeth due to lack of space. Crowding of teeth appears. This can cause abnormal taste and jaw formation. The dentist will decide after the examination whether to remove the “eights” or not.
- The seventh tooth in front may collapse– this happens if the wisdom tooth grows in an inclined position. Its anterior tubercles begin to rest against the seventh tooth located in front. Due to constant pressure on the enamel, it appears, which subsequently turns into pulpitis, and that into -. If left untreated, the tooth will crumble and fall out.
- The bite is disturbed- due to lack of space.
- Inflamed trigeminal nerve.
- May appearin the jaw.
- Pericoronitis (inflammation of the so-called “hood”)– when the first cusps of the tooth appear, its crown will be covered with mucous membrane. This mucous membrane is the hood. It gets inflamed very often. This inflammatory process is called pericoronitis. The cause of inflammation is food debris that remains in the semi-closed space between the surface of the tooth and the hood. The disease can occur in acute form.
Symptoms of pericoronitis:
- Swelling of the gum tissue.
- Leakage of pus from the hood.
- Unpleasant smell from mouth.
- Fever.
- It becomes difficult for a person to open and close his mouth.
A doctor can help relieve the disease by cutting the hood. The procedure will take a few minutes. In exceptional cases, the dentist may decide to remove the tooth.
When should I delete it?
- If the wisdom tooth is impacted and rests on other tooth processes.
- There is no way to put a filling on the figure eight due to individual characteristics development of the jaw or due to a tight fit to the adjacent tooth.
- Not all of it has come out and it causes discomfort; the gums have become inflamed.
- A negative phenomenon on the trigeminal nerve, which causes pain at its location.
- A cyst was discovered in the lower part of the jaw.
- In the area where the wisdom tooth appears, pain appears when swallowing, and periodically occurs headache and pain in the jaw muscles.
- Wrong location.
Contraindications for removal:
- If there is no 6 or 7 tooth in the jaw.
- If treatment is possible inflammatory process.
- If the dental process grows strictly vertically.
- Problems with work cardiovascular system.
- Viral infections.
- Initial and last stage pregnancy.
During the consideration of the topic, detailed answers to the questions posed were given. In the end, I would like to add that when teething eights, it is better to consult a dentist in time to avoid complications.
