If a wisdom tooth grows during pregnancy

Eights, also known as wisdom teeth or third molars, are the most “problematic” teeth. They are the last to erupt, from about 16 to 30 years of age. At this age, the jaw is already formed, so the eights simply do not have enough space in the dentition, so when they appear, they begin to cause discomfort.

A wisdom tooth affected by caries - treat or remove?

According to statistics, when affected by caries, in approximately 20% of cases, the wisdom tooth can be treated, in 80% it can be removed immediately. The question of treating or removing figure eights is decided by the dentist, taking into account the individual characteristics of a particular patient.

In what cases can experienced dentists treat caries of third molars:

• If the tooth is in satisfactory condition, the carious lesion is superficial or in the stain stage and there are no obstacles to successful treatment.
• It is very desirable to treat wisdom tooth caries if for some reason the patient has had his sixth or seventh teeth removed and the eights bear a large chewing load.
• Treatment of a wisdom tooth affected by caries is also necessary if the figure eights act as a support for orthopedic structures - bridges, crowns.
• Treatment is acceptable if there is no gingival “hood” hanging over the dental crown.
• It is advisable to preserve the tooth even if the opposite jaw also has a figure eight.

Features of growth

Unlike molars, eights do not have milk precursors in their buds. They erupt after the permanent teeth appear. You can see how this happens in the picture.

Eruption of wisdom teeth depending on age

When molars emerge, a crown forms on the third molar. Then, after a few years, roots begin to grow. Only after the wisdom tooth inside has fully formed does it begin to erupt.

How long does it take to cut?

The timing of wisdom teeth eruption varies from person to person. In some, the “eights” appear earlier, in others - later. Sometimes eights grow at the age of 16-17, but there are cases when they only begin to grow at the age of forty. Most often, 8 teeth erupt between 16 and 25 years; deviations from the norm are not a sign of disease, but should alert the patient. If at the age of 25 there are not even signs of eruption, it makes sense to consult a dentist to find out whether the tooth germ has formed in the gums or whether retention is taking place.

Difficulties that arise during the appearance of eights

In what cases does wisdom tooth treatment make no sense and must be removed?

• If the dentist has diagnosed “deep caries of the wisdom tooth,” it makes no sense to treat the disease at this stage. In this case, the tooth is simply removed.
• Figure eights affected by caries are removed if they are incorrectly located in the row of the masticatory-maxillary system.
• Extraction (removal) is carried out for chronic recurrent pericoronitis - if the patient regularly has inflamed gums around the eighth tooth.
• The figure eight should be removed if it injures the soft tissues of the inside of the cheeks. This happens when wisdom teeth are incorrectly positioned.

• Treatment of eighth teeth is not carried out if the patient cannot fully open his mouth or there are other obstacles to the procedure.
• Caries will not be treated if the third molars violate the position of the dentition and cause crowding of the canines and incisors. In such situations, the doctor often removes the figure eights and then performs orthodontic correction of the displaced teeth.
• Basal caries and cervical caries of wisdom teeth are also indications for removal in most cases.

Symptoms of the appearance of wisdom teeth

As a rule, the eruption of figure eights is accompanied by certain symptoms.

Pain in the gums.

It can be different: aching, pulsating or sharp. This all lasts for several days, or maybe the entire time the tooth grows.

Swelling and swelling.

Sometimes during the period of teething, swelling or swelling appears on the gums. In case of severe swelling, which is accompanied by severe pain and fever, it is recommended to consult a doctor.

Increased body temperature.

An abnormally growing wisdom tooth may be accompanied by an increase in temperature. If the values ​​do not go beyond 38 degrees, there is no need to worry - this is the norm. If the readings are higher, you should make an appointment with your dentist.

A sore throat.

Occurs during an infectious process. During teething, the mucous membrane is very vulnerable, so during this period it is necessary to devote more time to hygiene in order to avoid infection.

Early signs

The appearance of the last unit is accompanied by more striking signs, since there was no milk predecessor in its place.

Among the characteristic signs of teething are:

• pain, which in the most difficult cases provokes loss of consciousness;
• increase in body temperature to 39-40 degrees (usually observed with the development of infectious complications);
• swelling of the soft tissues of the mouth - cheeks, palate, gums;
• inflammation of the bone structures of the jaw and its destruction under the influence of pathogenic flora;
• formation of ulcers in the oral cavity;
• enlarged lymph nodes under the jaw.

If your wisdom tooth grows incorrectly

Complications often arise when figure eights are cut out incorrectly.

• Flux is a purulent inflammation of the periosteum.
• Cellulitis is a purulent inflammation, which is accompanied by an increase in temperature to 39 degrees and swelling of the face.
• Osteomyelitis is an inflammatory disease that affects bone tissue. Main symptoms: fever, nausea, vomiting, diarrhea.

If unpleasant symptoms occur, it is recommended to make an appointment with a dentist-surgeon. He will assess the condition of the tooth and help avoid the risks of complications. You can make an appointment with our specialists by calling: 220-86-30.

Causes of supernumerary teeth.

Until now, scientists have not figured out exactly why supernumerary teeth grow.

But there are several hypotheses according to which polyodontia occurs in humans:

-As a result of splitting of the tooth germ. Polyodontia can appear if the activity of the dental plate is impaired in the fetus during the embryonic period. This can happen due to various viruses, drugs, poor ecology, as well as the mother’s abuse of bad habits and medications during pregnancy.

-Because of atavism. There is a version that polyodontia occurs because the dental system seeks to increase the number of teeth, since nature originally intended 6 incisors on each jaw.

How to relieve pain when wisdom teeth erupt

The easiest way to get rid of unpleasant symptoms is to take over-the-counter painkillers.

• To relieve pain and fever: Nurofen, Ibuprofen, Nimesulide, Paracetamol.
• To eliminate pain: “Spazmalgon”, “Ketanov”, “Analgin”, “Pentalgin”, etc.
• Antiseptics to relieve symptoms and prevent complications: Miramistin, Chlorhexidine, Furacilin, etc.
• For local pain relief: “Kamistad”, “Kalgel”, “Cholisal”.

You can use folk remedies.

• Rinse solution made from salt and soda. Dissolve 1 teaspoon of salt and soda in a glass of warm water. It is recommended to rinse your mouth no more than 3 times a day.
• Rinse solution made from propolis tincture. Stir 7-8 drops of tincture in a glass of warm water. The solution is also a natural antiseptic.
• Cold compress. Under no circumstances should it be hot - heat may cause inflammation.
• Sage decoction. Pour 1 tablespoon of sage into a glass of boiling water, leave for an hour, strain. You can rinse until relief occurs.

Relieving pain during wisdom tooth eruption is only a short-term solution. A competent consultation with a doctor will help you cope with pain and possible complications.

Peculiarities of eruption of the last molars

In most adult patients, the process is accompanied by malaise and pain. Often the condition requires medical attention. The danger of teething eights is due to the fact that the jaw of an adult patient has already been formed, and the remaining teeth have taken a certain place. If the last element does not have enough space in the oral cavity, then it begins to displace neighboring units or grow towards the cheek.

Pathological eruption is accompanied by intense pain, severe swelling, fever, bad breath, and temporary disability. There are several types of abnormal placement of wisdom teeth:

• horizontal;
• retent;
• rotated around its axis.

Often the figure eight is covered on top by a hood, which during the process of eruption becomes inflamed and causes pain. Food falling on the hood of a wisdom tooth creates favorable conditions for the development of dental diseases - caries, pulpitis, periodontitis, etc. With this problem, there is only one way out - to remove the hood through surgery, and with it the problematic element. Symptoms of complications due to untimely medical care: inflammation of the lymph nodes, pain when swallowing saliva and food, purulent discharge when pressing on the gums.

Signs associated with pathological eruption are manifested by neurological problems, cysts on the root of the tooth, which should be removed at the beginning of development to prevent complications. The process of removing a figure eight is a difficult task, especially if the figure has crooked roots or is not positioned correctly in the mouth. After surgery, patients often complain of discomfort in the area of ​​the removed unit. Normally, discomfort should disappear after 2-3 days.

How long do wisdom teeth grow?

Retention or incomplete eruption of wisdom teeth causes considerable problems for patients. Such cases require removal of the unit. Signs of retention:

• swelling of the gums;
• lack of visualization of the tooth on the gum surface;
• redness and soreness of soft tissues in the eruption area;
• temperature increase.

Retention may not be accompanied by discomfort.

Often the unit climbs towards the seven and injures it. If the wisdom itch constantly presses on the neighboring tooth, then the enamel of the latter is gradually destroyed, which leads to caries.

Should I keep or delete the problematic unit? Only a doctor can answer the question after assessing the symptoms of the pathology and taking an x-ray.

You should not get rid of the figure eight on your own: these teeth may be useful in the future for attaching bridges to them and for other purposes. Direct indications for the operation are: the direction of growth of the element towards the cheek, horizontal position or lack of space in the oral cavity for complete eruption.

At a time when the last molars are growing, it is necessary to take especially careful care of the oral cavity. Between the figure eight and the hood, food debris accumulates, which is quite difficult to remove.

When cleaning the oral cavity, it is better to use not only a brush and paste, but also an irrigator

After each meal, the mouth is treated with antiseptic compounds or a solution of potassium permanganate. These measures will prevent pathogenic flora from entering the erupting tooth.

What measures to take if your wisdom tooth hurts? There is no need to constantly take painkillers in the hope that the situation will resolve itself. The first signs of illness require immediate medical attention. The problem unit will constantly remind itself if medical treatment is not carried out.

If a wisdom tooth grows during pregnancy

If the eights began to grow during pregnancy, then the expectant mother should make an appointment with a doctor. This will help protect the baby from negative consequences and significantly improve the well-being of the pregnant woman. If there are unpleasant symptoms (improper position, pain, inflammation), the dentist may recommend removing the wisdom tooth. In this case, it is better to do this in the second trimester, when the operation will not harm either the mother or the child. At other times, it is not recommended to carry out any procedures unless there is a threat to the health of the woman and baby.

Structural features

All structural features of the teeth of this group come down to their roots. Wisdom teeth are multi-rooted teeth (2 or more). Often they are spliced ​​or bound

They interact with each other and also have a curved shape, which creates problems in treatment. The fact is that curved root canals prevent proper mechanical treatment and high-quality filling of teeth.

Sometimes, during the development of jaws, the rudiments in one row of teeth change places. In this case, the eighth tooth that is not typical for this location (abnormal) is erupted, which may have one root.

The coronal part of wisdom teeth has a fissure characteristic of a chewing tooth.
