I am twenty years old, and I have three more teeth, all of which are at the bottom, totaling ***3 1 tooth. Who can tell me what is going on and how to deal with it?

Wisdom teeth, the scientific name of the third molar, commonly known as wisdom teeth, upright teeth and complete teeth, are the teeth closest to the throat in the mouth. If they all have one ***4 teeth, and two teeth in the maxilla and maxilla, they usually grow over 16 years old. Compared with deciduous teeth and permanent teeth replaced in childhood, wisdom teeth usually grow when people's minds are mature, hence the name.

Symptoms of long wisdom teeth

The symptoms of long wisdom teeth are often due to incomplete eruption of wisdom teeth, a part of the crown is surrounded by gums, forming a blind pocket, and food residues are easy to enter but difficult to exit, resulting in swelling of soft tissue around the crown and pus accumulation in the blind pocket. The patient will have symptoms such as pain, difficulty in opening his mouth and fever.

Long wisdom teeth are often ectopic or impacted due to insufficient eruption position, and the crown is partially exposed outside the gum and partially covered by the gum. A narrow and deep blind bag is formed between the gums and teeth, which is easy to accumulate food residues and bacteria, and it is difficult to clean up after brushing and gargling. In addition, the crown and gums are easily damaged by chewing food, forming ulcers and other symptoms.

When the systemic resistance decreases and the bacterial virulence increases, it can cause inflammation of the tissues around the crown. In the early stage of pericoronitis of wisdom teeth, due to mild symptoms, it is often ignored by patients and delayed treatment, which leads to the rapid development of inflammation and aggravation of the disease.

In the process of human growth, there are two pairs of teeth: one is called "deciduous teeth", which can only accompany us through a happy childhood. At the age of 6, these teeth will complete their historical mission and retire with honor.

From the age of 6 to the age of 12 ~ 13, the deciduous teeth are constantly replaced by the second set of teeth (permanent teeth), with 28 ~ 32 permanent teeth. Permanent teeth are divided into four categories according to their shapes and functions, namely incisors, canines (these two are what we often call incisors), bicuspids and molars (these two). With the development of the human body, these teeth are constantly erupting and generally have no special feeling.

In the primitive human stage, the height and width of teeth are decreasing due to the wear of coarse food, and the posterior teeth have enough space to move forward in turn, so that our third molar (that is, wisdom teeth) can begin to erupt around 16 years old.

However, with the development of modern food, tooth wear is decreasing. At the same time, due to the reduction of the stimulation of chewing fine food on the jaw bone, the jaw bone gradually degenerates and shrinks, which inevitably leads to insufficient space for tooth eruption, and the eruption time of wisdom teeth is postponed to adulthood, that is, 18 to 30 years old. Because this stage is generally considered as the peak of intellectual development, people often call this tooth "wisdom tooth".

Wisdom tooth is the third molar, commonly known as "Lishi tooth" and the last tooth in the dentition. This tooth erupted between 18 and 30 years old, so it is called Lishi tooth.

The mandibular structure has not been fully exercised in chewing function, and gradually degenerates, and the number of teeth is larger than that of the mandible. Therefore, when the third molar grows out, it is often not enough and it is difficult to erupt, forming "impacted wisdom teeth", which is a common disease of young people.

Impacted wisdom teeth can lead to malocclusion, pericoronal space infection, difficulty in opening mouth, caries of second molar, and even osteomyelitis of jaw.

If it is found that wisdom teeth are repeatedly impacted and cause inflammation, they should be removed as soon as possible to avoid other symptoms or diseases. If pericoronitis of wisdom teeth has formed, antibiotics should be given and removed after the inflammation is controlled.

Only a few mandibular wisdom teeth can erupt normally, which has a normal jaw-biting relationship. Because there is not enough space, "wisdom teeth" tend to grow crooked when they erupt, such as leaning to the buccal side or lingual side, leaning forward and backward, and so on.

It often happens that only a part of the crown is exposed outside the gum, and the other part is covered by the gum, that is, a narrow and deep bag-like structure is formed between the gum and the tooth, which is called "blind bag" in medicine, also known as "gingival bag". Food residues and bacteria are easy to accumulate in the gingival pocket, and it is difficult to clean them when brushing your teeth and gargling. In addition, dental crowns and gums are prone to local injuries and ulcers due to chewing food. When the systemic resistance decreases and the bacterial virulence increases, it can cause inflammation of the tissues around the crown, that is, pericoronitis of wisdom teeth.

There may be two reasons for the degeneration of wisdom teeth in this section:

First, in the process of human evolution from apes, the mandible became smaller and there was no room for wisdom teeth.

Second, it may be related to oral hygiene. It is common for young people in ancient times to have more teeth or to lose most of them. At this time, the wisdom teeth that have just grown come into play. Modern stomatology is developed, and everyone has the habit of brushing their teeth. Unless there is an accident, young people's teeth will generally remain intact and wisdom teeth will become redundant. Because there is no room for growth, wisdom teeth often feel pain when they grow, and their position and direction will be abnormal after eruption. Most people's wisdom teeth have no chewing function and no occlusion. In other words, wisdom teeth are generally redundant.

Edit whether the wisdom teeth related to this paragraph should be extracted. If the position is good and the upper and lower occlusal relationship is normal, then of course it is not necessary to pull it out. But if the position is not good, I suggest you pull it out, because bad wisdom teeth will bring some inconvenience to your later life, such as inflammation when your own resistance drops. I can also tell you that wisdom teeth are useless in the mouth, and pulling them out will not hinder the oral function. According to medical knowledge, wisdom teeth are the teeth that people begin to grow in adulthood. The average child will grow 28 teeth after deciduous teeth fall off, and adults will grow 4 teeth, that is 32, which means you have grown up!

If the wisdom teeth have enough positions, the teeth grow vertically like normal teeth, and the upper jaw also has a corresponding third molar bite, so it is not necessary to pull them out after the inflammation subsides. In order to avoid the recurrence of pericoronitis of wisdom teeth, if the position of wisdom teeth is not correct, there is not enough eruption position, and the third maxillary molar is not correct or has been extracted, the wisdom teeth should be extracted as soon as possible. Now that the inflammation has subsided, readers can go to the hospital for an X-ray, and the doctor will decide whether to remove it. [1] Wisdom teeth come from wisdom teeth, also called the third molar. Wisdom tooth is the last permanent tooth among 32 human permanent teeth, which is located in the upper, lower, left and right teeth.

wisdom tooth

The last side of the bow. Because wisdom teeth are mostly around 16 ~ 24 years old when they grow up, people's wisdom is also referred to as wisdom teeth when they grow up. In the process of human evolution, as the food becomes more and more refined, the burden on the jaw bone decreases accordingly, which leads to the continuous reduction of the bone mass of the jaw bone, but the size of the teeth does not decrease with it, which eventually leads to the lack of teeth eruption. The third molar that finally erupts is the most likely to form pericoronitis of wisdom teeth, which is the main reason for the abnormal eruption position of wisdom teeth. The origin of wisdom teeth refers to the four third molars on the innermost alveolar bone in human mouth, one on the top, one on the bottom, one on the left and one on the right. Because these four third molars just began to erupt around the age of 20, people's physical and psychological development is close to maturity at this time, so they are regarded as a symbol of "wisdom arrival", so they are called "wisdom teeth".

The incidence of impacted wisdom teeth in this section is high, and its harm is mainly manifested in the following points:

Recurrent pericoronitis is inevitable when the soft tissue around the crown of wisdom teeth forms a blind pocket with the teeth, which causes food and bacteria to accumulate and the resistance decreases. The general anti-inflammatory treatment is to treat the symptoms rather than the root cause, so pericoronitis will recur.

It is easy to accumulate food residues between wisdom teeth with incorrect dental caries and second molars, and it is not easy to clean them up. Generally, dental caries can form in a few months, which directly destroys tooth tissue.

Wisdom teeth with mandibular pain and impacted molars often fail to establish a normal occlusal relationship with the opposite teeth, which can lead to long-term symptoms such as snap of temporomandibular joint, mouth pain and night molars, which have a great impact on the physical and mental health of young adults.

There is evidence that some impacted wisdom teeth are the focus of some trigeminal neuralgia.

The mandible holding the teeth is getting smaller and smaller, and it is an inevitable result that wisdom teeth are impacted. Extraction of impacted wisdom teeth has no adverse effect on mastication, language and other functions, and extraction is the most effective method to treat impacted wisdom teeth. Therefore, it is suggested that impacted wisdom teeth should be removed decisively as soon as possible.

Generally speaking, wisdom teeth rarely grow well. What does it mean to grow up? Either it won't grow out or it won't grow straight. If it doesn't grow, the gums will cover the wisdom teeth, leading to gum inflammation and bad breath. Improper growth means that wisdom teeth can't grow as normal teeth. It is likely to make normal teeth tilt and resist, with serious consequences. As long as it doesn't grow well, it will become inflamed once every six months or so until you pull it out. Generally speaking, people with wisdom teeth will consider pulling out their wisdom teeth when they are inflamed, but they will forget about it after they get better. So, don't take chances. The process of extracting wisdom teeth is simple. The doctor will inject anesthetic into your mouth, and then eat too much ice cream and your mouth will feel numb. Don't be afraid. However, one thing to remind you is that before the wisdom teeth are pulled out, if there is inflammation, the doctor will give you anti-inflammation, and then pull them out after the inflammation disappears. In other words, if you go to the hospital when your wisdom teeth don't hurt, you can save a doctor's procedure.

Long wisdom teeth can be a little painful, but everyone's situation is different.

Try to keep your teeth, and don't pull them out if you can, because tooth extraction may hurt your nerves. So many people often ask: should wisdom teeth be pulled out? Usually, dentists will recommend the removal of wisdom teeth for the following reasons:

1. Tooth decay: If wisdom teeth suffer from tooth decay, we recommend pulling them out, except for simple tooth decay with shallow occlusal surface, those adjacent teeth that need good skills, and those with deep tooth decay or even root canal treatment, so as to prevent future troubles.

2. Adjacent tooth invasion: Usually the patient does not know, but is diagnosed by the dentist with X-ray. Usually, wisdom teeth don't have enough space to germinate, but they will fall on the second molar, which makes the second molar difficult to clean and even partially absorbed by the teeth, bringing discomfort or toothache to patients.

3. Lack of space: wisdom teeth are in a state of disappearance in the history of human evolution. Therefore, the dental arch is getting smaller and smaller, and the lack of space is very common. Swelling and pain can be felt most when sprouting. Many people decide to have their wisdom teeth removed because they can't stand the pain.

4. Cleaning is not easy: due to lack of space, wisdom teeth often grow crooked, which often makes it difficult to clean teeth and lead to tooth decay.

5. No gnashing of teeth: As mentioned above, not everyone will have four wisdom teeth. Therefore, on the opposite side of wisdom teeth, if there is no competitive wisdom teeth occlusion, sometimes wisdom teeth will erupt excessively, affecting occlusion.

6. Impacted tooth: Usually this is the most annoying one. Dentists will find it difficult to repair, but patients may not feel it, so they ignore it. This type of tooth is usually buried in alveolar bone. If it hurts, or a lesion is diagnosed, it needs to be removed.

If you want to pull out wisdom teeth, you must find a professional dentist. Don't drink carbonated drinks such as cola before tooth extraction, otherwise the teeth will break easily and it is difficult to pull out the roots. Moreover, after tooth extraction, attention should be paid to:

1. Usually, the longer the extraction time, the longer the swelling time, especially for impacted teeth.

All blood and saliva should be swallowed within one hour. Don't rinse your mouth to help blood clots and wounds heal.

You need ice compress two days before you go home, and use hot compress if you feel uncomfortable two days later.

If you have a fever, you can call in sick the next day.

5. Gingival inflammation is not suitable for wisdom tooth extraction. Take anti-inflammatory drugs before tooth extraction to eliminate inflammation.

6. You can't pull out wisdom teeth during menstruation.

After talking about the extraction of wisdom teeth, you may still have doubts: if there are no symptoms, is it not necessary to extract them?

If you are in the position of a doctor, he will generally advise you to unplug it to avoid future troubles, so it is a painful and lifelong immunity. However, if you think wisdom teeth are not in the way, then you can decide whether to pull them out or not. So, what kind of wisdom teeth are worth keeping?

1. The position is relatively positive, and it is expected to explode normally.

2. There is no history of inflammation and pain in the soft tissue around the crown of wisdom teeth, and there is no dental caries in wisdom teeth.

3. Wisdom teeth with molars.

Extraction principle

Under normal circumstances, wisdom teeth with normal growth should be kept as much as possible and should not be pulled out at will. Especially wisdom teeth that have been growing for many years. Only when there are various clinical symptoms of abnormal growth, it needs to be removed! Before removing wisdom teeth, you must take a dental film to determine whether the growth of wisdom teeth is abnormal. Inflammation of wisdom teeth is not necessary. As long as the inflammation disappears and does not recur, you can not pull it out.

Note for editing this paragraph: 1. All blood and saliva should be swallowed within one hour. Don't rinse your mouth to help blood clots and wounds heal. [2]

2. Don't drink and eat Chili.

3. Pay attention to rest and don't stay up late, especially from 10 to 2 pm, which is the best time for body repair and needs to be repaired during sleep.

Don't take part in strenuous exercise, there is no problem with basic daily activities.

Don't rinse your mouth with water on the first day of tooth extraction. The diet temperature should not be too cold or too hot, but a little cooler.

6. Don't talk loudly, laugh and lick with your tongue.

7. Ice for an hour after you go home, and then use hot compress if you feel uncomfortable.

8. If you have a fever, you can call in sick the next day.

9. Gingival inflammation is not suitable for wisdom tooth extraction. Take anti-inflammatory drugs before tooth extraction to eliminate inflammation.

10. You can't pull out wisdom teeth during menstruation.

Sleep and diet for the next few months after tooth extraction.

About the tooth cavity after tooth extraction:

1. The long flattening time of tooth cavity varies from person to person, generally speaking, it is 2-3 months.

2. The food residue in the tooth cavity must be cleaned up. Food residue is not only a hotbed for the growth of various oral bacteria, but also produces oral odor, increasing the chances of suffering from various oral diseases. Chew and swallow food with normal teeth on the other side.

Don't eat anything with pungent taste and temperature, especially something that is too spicy or too hot. Bring some salt to work and rinse your mouth with salt water after every meal.

Complications caused by wisdom teeth: Impacted or misaligned wisdom teeth easily embed food residues in the interdental and periodontal spaces between the second molar and wisdom teeth, which is difficult to remove and often leads to dental caries. According to the survey; The average caries rate of mandibular second molars is 65438 06.4%, with significant differences among different ages, only 3.7% at the age of 20 and as high as 27% at the age of 50. It can be seen that the removal of impacted or dislocated wisdom teeth is the key to prevent the caries of the second molar, and shallow caries may not develop.

Uneven dentition: 14- 18 years old is the most active period of wisdom teeth eruption, but due to the imbalance of jaw bone mass and tooth quality, the space for wisdom teeth eruption is limited. Therefore, the driving force of wisdom teeth eruption is often one of the main reasons for the crowded and irregular arrangement of teeth. The continuous driving force of this eruption movement is only 4 ~ 5 grams, which is enough to affect the second molar. Therefore, the dislocation and torsion of the second molar are more common, accounting for about 20% of patients with dentofacial malformation, of which about 80% occur in the mandibular second molar; Most of them are teenagers, and women are about 1.6 times that of men. The dislocation of the second molar will reduce the contact area of the upper and lower jaws and obviously reduce the chewing function of people.

Absorption of adjacent teeth and supporting tissues: during the tooth germ development of mandibular wisdom teeth, the long axis of the teeth was originally inclined forward, and only when the mandible developed sufficiently did it gradually erupt upright. When it is blocked by the second molar during eruption, tooth-destroying cells attached to the root surface of the second molar will be produced there. Tooth-destroying cells can release lysozyme and gradually absorb the root, and in severe cases, they can completely absorb the distal root of mandibular second molar. Moreover, chronic periodontitis, which often exists between impacted wisdom teeth and second molars, can also cause inflammatory absorption of alveolar bone.

Craniomandibular disorder: Impacted or dislocated mandibular wisdom teeth often interfere with the maxillary second molar, leading to pathological retraction of the mandible, which is one of the reasons leading to craniomandibular disorder. The main clinical manifestations are snap of temporomandibular joint, pain and abnormal mandibular movement, masticatory muscle pain, tinnitus, tongue pain and other symptoms. After extraction of impacted or dislocated wisdom teeth, many patients have achieved remarkable results because of blocking the potential factors that lead to the disorder of craniomandibular relationship.

Cystic lesions around wisdom teeth: odontogenic cystic lesions of jaw are prone to unexplored embedded teeth, and the mandibular wisdom teeth have the highest probability of being blocked from erupting, which is obviously the main prone site. When the cyst develops to a certain extent, the jaw can be swollen and deformed, and once it is infected, it will cause repeated swelling and pain, and even cause pathological fractures in severe cases.

Precancerous lesions of oral mucosa: Impacted and dislocated gingival and buccal mucosa of wisdom teeth may cause ulcer, erosion, abnormal tissue proliferation, leukoplakia and other pathological damage due to long-term mechanical stimulation or repeated occlusion of crown edge. Such a long-term wound repair and re-trauma process will affect the normal keratinization of oral mucosa epithelium, cause precancerous lesions, and then induce oral mucosa canceration.

Pericoronitis of wisdom teeth: When impacted, wisdom teeth may erupt in different directions, such as vertical, forward, horizontal, horizontal and inverted. When it partially erupts, the periphery of the crown is often covered by gingival tissue to varying degrees, thus forming a gingival pocket between the crown and the gum. When the depth exceeds 2 ~ 3 mm, it often leads to lesions. Because food residues are easy to hide in this bag and bacteria are easy to multiply, inflammation will occur when the gum bag is traumatized or the body's resistance decreases. The onset age of pericoronitis of wisdom teeth is 20 ~ 25 years old, and almost 95% of it occurs in mandible. It is often manifested as swelling and pain of pericoronal tissue, which affects chewing and swallowing, and is often accompanied by systemic symptoms such as difficulty in opening mouth, fever and swollen lymph nodes. If the inflammation is not controlled in time, it can also spread to the jaw and neck, resulting in inter-tissue infection, osteomyelitis of the jaw, and even serious systemic complications such as sepsis and pericarditis.

What are the manifestations of pericoronitis of wisdom teeth and how to diagnose it [3]

1. Most of them are young people, especially 18 ~ 25 years old. Have a history of systemic predisposing factors or recurrent attacks.

2. There is generally no obvious systemic reaction in the early stage of acute pericoronitis. Patients feel pain and discomfort in the affected area, and the pain is aggravated when chewing, swallowing cigarettes and opening their mouths. The examination showed that the impacted teeth and posterior molars were swollen, and there were purulent secretions in the pericoronal pocket.

3. Inflammation develops further, involving masseter muscle and medial pterygoid muscle, swelling of mandibular angle, limited mouth opening to varying degrees and even inability to speak. Systemic symptoms are obvious, and submandibular lymph nodes are often swollen and tender. If not treated in time and reasonably, it can develop into pericoronal abscess, cellulitis in maxillofacial region and even osteomyelitis.

4. Chronic pericoronitis can form fistula on the buccal side of mandibular first molar or skin fistula at the front of masseter muscle.

The main symptom of acute pericoronitis of wisdom teeth is swelling and pain of soft tissue around the crown. If inflammation affects the masticatory muscles, it can cause different degrees of mouth opening restriction, and if it affects the pharynx, it will cause swallowing pain, making it difficult for patients to chew, eat and swallow. Seriously ill patients can still have general symptoms such as general malaise, headache, elevated body temperature and loss of appetite.
