Wisdom teeth: problems they can cause

• the gums around the wisdom tooth are inflamed: what to do,
• wisdom tooth: hood and its removal (price for 2021),
• how to relieve inflammation.

The article was written by a dental surgeon with more than 19 years of experience.

Difficulty in the eruption of wisdom teeth is often accompanied by the development of inflammation of the gums around them. The mucous membrane of the gums, which partially covers the crown of the erupting wisdom tooth, is called the wisdom tooth hood (Fig. 1-3).

Because The hood over the wisdom tooth is not tightly adjacent to the crown of the tooth - a semi-closed space is formed between them, in which favorable conditions are created for the proliferation of pathogenic bacteria and the development of inflammation. In dentistry, an inflamed hood on a wisdom tooth is usually called “pericoronitis.”

What is complex wisdom tooth extraction?

Tooth extraction is called complex if the tooth has several roots, and the operation will require an incision into the soft tissue of the gums and, possibly, the periosteum. Another difference from classic removal is the need to use additional tools (except for forceps and an elevator). The difficulty of performing surgical intervention is due to the difficulty of accessing the extreme elements of the dentition, the root features of the “eights” and the specifics of the clinical case (they are often dystopic or impacted).

Important: you cannot postpone the removal of the defective “eight”. This can lead to suppuration and, as a consequence, to the formation of an abscess and the development of sepsis.

Differences between figure eight removal on the lower and upper jaws

Removing a third molar in the lower jaw is considered a more complex procedure than removing a wisdom tooth in the upper jaw for a number of reasons.

1. Access to the lower molars is more difficult than to the upper ones.
2. The lower jaw bone is more massive and dense, it holds the tooth more firmly.
3. The pressure on the teeth of the lower jaw is greater than on the upper teeth, so the roots of the lower molars are more developed. In addition, due to improper growth, they can be curved or misaligned.
4. It is easier to perform local anesthesia from above, and anesthesia from the bottom often involves the muscles of the face, tongue, throat and ears.

All this makes the procedure for removing the 8th tooth from below a difficult task. If the upper molars in most cases can be easily rocked and pulled out with special forceps, then the lower molars often have to be removed in parts, cutting with a drill.

Indications and contraindications for surgery

Indications

Surgery is necessary if the wisdom tooth:

• Dystopic (the direction of growth is changed towards adjacent teeth, tongue or cheek)
• Impacted (not fully or not fully erupted)
• Has roots that are too long (this may initiate their penetration into the maxillary sinus or fusion with the jaw)
• Caused inflammation of the “hood” of the gums or periodontal tissue (pericoronitis)
• Caused the formation of a follicular cyst, phlegmon, gumboil or fistula
• Destroyed due to the development of caries or other dental disease
• Caused inflammation of the trigeminal nerve
• Became a source of permanent injury to the oral mucosa
• Interferes with the eruption of other molars with a narrow jaw

Absolute contraindications:

• Malignant tumor in the root zone
• Hemangioma (benign formation)
• Serious chronic cardiovascular problems

Relative (temporary) prohibitions:

• Infectious diseases, including those of the oral mucosa
• Having had a heart attack or stroke
• Taking anticoagulants
• Exacerbation of psychoneurological diseases
• Pregnancy and breastfeeding (except for emergency indications)

Features of caries on figure eight

The cause of this disease is the accumulation of bacterial plaque and poor hygiene. “Eights” erupt late, on average after 18 - 20 years, and sometimes remain partially unerupted (impacted). At the same time, wisdom teeth are located far in the oral cavity, and it is almost impossible to clean them properly. If part of the crown is located under the gum, a so-called gum hood is formed, where food particles easily fall, and the tooth is destroyed even faster. These factors are the main reasons for the appearance of caries on the figure eight.

Removing the "hood"

Often, difficult eruption of a wisdom tooth leads to inflammation of the gums that cover it (“hood”). This causes enlargement of the lymph nodes, increased temperature, pain when chewing, injury to the gums and, as a result, rapid proliferation of pathogenic bacteria, leading to inevitable suppuration. This situation occurs quite often and is an indication for excision of gum tissue. If the “eight” under the hood is viable and does not cause inconvenience, then it is not removed.

Reasons for the formation of pus in the gums

There are several reasons for the formation of pus:

• The inflammatory process causes a disease such as periodontal disease (gingivitis).
• Periodontal disease.
• Mechanical damage to the gums.
• Chemical or thermal burn.
• Unprofessional removal of tartar, which affected the gums.
• Extensive caries causes pulpitis.
• Failure to comply with hygiene standards when performing dental procedures.
• Unsanitary oral cavity.
• Types 1 and 2 diabetes mellitus.
• Summing up the causes of purulent inflammation of the gums, we can highlight the main factor that causes this disease – the vital activity of pathogenic microorganisms.

Types of anesthesia

Performing surgical interventions is impossible without high-quality anesthesia. During extractions, the following types of anesthesia can be used:

• infiltration anesthesia – provides a local effect. Injected with a syringe into the gum or intraosseously. This is the most common option for dental procedures;
• conductive - has a more powerful effect and is used when operating on particularly complex cases. The injection is carried out to the branches of the trigeminal nerve;
• intraligamentary - used to anesthetize one tooth. The medicine is injected with a syringe into the ligament that holds the tooth in the alveolus.

Expert opinion: Some patients want dental surgery to be performed under general anesthesia. But this type of anesthesia is not as harmless as it is described in advertising articles. It has been proven that it negatively affects the patient's health. An operation to remove teeth, even such complex ones as the “eight”, is not a direct indication for the use of general anesthesia (with rare exceptions). Surgery is painless with the correct selection of local anesthetic. Therefore, you should not strive for general anesthesia and put unnecessary drug burden on the body.

Expert opinion

Emir Romanovich Omerelli

Maxillofacial surgeon, implantologist

Experience: more than 13 years

Impacted wisdom teeth are a “popular” reason for patients to visit dental clinics. In approximately half of all cases, the eighth teeth erupt with problems, and retention is the most common. It is interesting that the age of patients can be different - from 18 years to deep retirement age. It all depends on how much the impacted tooth bothers the patient. However, the sooner the problem is solved, the less problems an unerupted tooth will cause.

After surgery, it is very important to follow the precautions recommended by your doctor: you must refrain from eating for two hours after tooth extraction. For a couple of days, the food consumed should be warm - not too hot and in no case cold. It is necessary to chew on the side opposite to the operation site. You should also avoid physical activity for a while. You can brush your teeth, but as carefully as possible so as not to damage the sutures. Do not forget about the need to take antibiotics and medications that restore the body’s immune system - they will be prescribed by your doctor.

Other jobs

Instruments used during surgery

When performing complex extractions, the surgeon may need the following instruments:

• forceps – for extracting a tooth or its elements if they can be grasped. There are different shapes: straight, curved, S-shaped;
• elevator - for loosening entire dental units or their roots in the alveolus;
• excavator - for removing fragments from a deep root fracture;
• scalpel - for cutting soft tissues;
• drill or chisel - for sawing (splitting) large elements of the root or coronal parts with a very dense bone structure.

How is the procedure performed?

Before starting the procedure, the dental surgeon takes into account all the individual characteristics of the patient: age, allergic reactions, chronic diseases, etc. After making sure that the procedure can be carried out, the doctor begins excision.

Stages of excision of the hood:

• X-ray diagnostics.
• Local anesthesia.
• Gum incision.
• Washing the wound.
• Applying a therapeutic bandage.

After surgery, the doctor schedules a follow-up appointment to examine the wound. As a rule, the gums heal in about ten days. If the process is delayed, this may be a symptom of complications.

Stages of surgery

The G8 extraction protocol implies a strict sequence of certain stages:

• diagnosis of the clinical situation. It is carried out by the surgeon when the patient comes for an appointment. First, the doctor conducts a visual examination, determining the extent of damage to the tooth and surrounding tissues. Next - mandatory radiography for an objective assessment of the current condition. The image allows you to clarify the details of the clinical case: the number of roots, possible interweaving, angle of inclination. If necessary, the examination is supplemented by orthopantomography (obtaining an image in 3D format);
• determination of the type of anesthetic and its dose. Questioning the patient about the presence of allergic reactions to any medications;
• injection of an anesthetic drug into the surgical area. The mechanism of action of the anesthetic is as follows: the substance acts on the nerve, it stops transmitting impulses to the brain. As a result, after 5 to 10 minutes a person stops feeling pain in the place where the medicine was injected. After some time (up to 6 hours), it stops working, the transmission of nerve impulses is restored;
• the operation itself. Typically lasts from 30 minutes to one and a half hours. Complex removal involves cutting the gums with a scalpel and stitching them together upon completion of surgical procedures. An incision into the gum tissue allows the surgeon to reach the root system. Then the doctor, using a drill and/or chisel, saws (splits) the molar into several parts and takes it out in separate pieces. If necessary, the roots are taken out in the same way. After all parts are removed, the hole is treated with an antiseptic, and the incision is sutured with surgical threads;
• At this point the operation ends, the surgeon gives the patient recommendations on oral care.

Note: extraction can only be performed by a qualified dental surgeon in a medical institution in compliance with aseptic and antiseptic standards.

When to carry out the procedure and when to refrain from it

Indications for the procedure:

• strong pain;
• the appearance of putrid odor from the mouth;
• discharge of pus from the gums;
• swelling, bleeding and soreness of the gums;
• general weakness, elevated body temperature, dizziness and nausea (such symptoms are a sign of intoxication of the body).

Contraindications:

• mucosal infections (stomatitis, herpes, gingivitis, periodontitis);
• infectious diseases of the upper respiratory tract (sore throat, pharyngitis, laryngitis, etc.);
• exacerbation of chronic diseases.

Possible complications

Successfully performed surgery and following the doctor’s recommendations minimize the risk of complications. But they are still possible. This:

• severe pain that continues for several days;
• heavy bleeding from the surgical wound;
• inflammatory process (characterized by swelling of the gums, cheeks, and a significant increase in temperature);
• osteomyelitis of the jaw;
• loss of sensitivity in some areas of the face (parasthesia). Possible if the facial nerve is damaged.

Attention! All of the above symptoms are a good reason to immediately consult a doctor. Waiting “for it to resolve on its own” is unacceptable; this can lead to serious consequences, including sepsis.

Causes of rotting

In the first place is fear. It is the irrational fear of the dentist, which is difficult to control, that makes us put off visiting the doctor. Often to the point where it is no longer possible to save the tooth. No matter what facts they give us, no matter how much we persuade ourselves, phobias do not lend themselves to rational arguments.

But this is far from the only reason.

General diseases

Our body is a single system. Discord in one place leads to problems in another. Thus, diseases of the gastrointestinal tract cause dental problems.

Infections, fungal diseases, even hormonal imbalances often lead to inflammatory processes in the mouth.

Ecological problems

In regions where drinking water is of poor quality, dental problems are 3-4 times more common. The same picture is observed where there are large industrial enterprises. Increased amounts of toxic microelements in the environment harm overall health and negatively affect teeth.

Diet

There are foods that provoke the growth of bacteria in the oral cavity, which means they contribute to tooth decay. Yes, that same sugar, but not only that. Acids formed during the fermentation of carbohydrates are the main enemies of enamel.

Lifestyle

Addictions of any kind are not good for dental health. Cigarettes, drugs, alcohol are a direct path to problems.

This also includes restrictive diets. Vegetarians, vegans, and Keto fans need to carefully ensure that the body receives all trace elements and vitamins.

Oral diseases

Inflammatory processes in the mouth are a haven for bacteria. Therefore, it is important to regularly carry out sanitation and ultrasonic cleaning of teeth. Periodontal disease, periodontitis, stomatitis, gingevitis, cheilitis require special treatment, which is better not to delay.

Oral hygiene

This is perhaps the easiest way to destroy teeth. All that’s left to do is brush and floss twice a day. 90% of the population does this, but not as carefully as we would like. There are special teeth cleaning schemes. They involve treating surfaces from all sides and for a certain time. Unfortunately, now

90% are those who brush their teeth for less than 1 minute.

Genetic predisposition

Alas, often all preventive measures are not able to help keep teeth safe and sound. Healthy, strong teeth, just like bad ones, are inherited.
