How Long Does Dental Numbing Last

After removing the wisdom tooth does not pass numbness of the lip and chin

Many of us do not like to go to the dentist, but there are situations when a visit to the doctor to postpone will not work, and one of them — the removal of the wisdom tooth. We go into the office, sit in the dental chair and wait for the injection of painkillers to somehow alleviate our suffering. The anesthesia will kick in and the surgery will begin. When it’s over, the dentist will give us recommendations for the care of the postoperative wound and let us go home.

It seems possible to exhale with relief, however, whaa t to do if after 2-3 hours the analgesic does not pass? After a couple of hours of numbness captures the lips, chin, and part of the cheek, there are tingling and discomfort in these areas. Do not panic, you have paresthesia (numbness) — a fairly frequent complication of the operation to remove the wisdom tooth.

How long does dental numbing last?

After removing the wisdom tooth Or Novocaine is injected, you are going to begin to feel numb after 5 to 10 minutes. The tingling sensation normally lasts 30 to 60 minutes.

Numbness after extraction of the wisdom tooth is a normal phenomenon. It may appear due to prolonged pressure on a certain area of soft tissues during manipulation. Under favorable circumstances, this phenomenon disappears within 1-10 days. Otherwise, persistent paresthesia develops, when the area of the head is numb and not felt by the patient for 2-3 weeks to six months.

What is paresthesia?

Paresthesia is the numbness of areas of the face, lips, cheeks, chin, tongue, due to damage to the jaw or facial nerve in the process of removing the wisdom tooth.

The syndrome can last from several days to several months or years. In any situation, the outcome is positive-numbness eventually passes completely.

Eight begins to erupt with about 20 years, and it is desirable to get rid of it immediately. The earlier the third molar is removed, the less likely the paresthesia. This is due to the fact that poorly settled teeth are easier to pull out, which means that the surgeon performs less traumatic manipulations that increase the likelihood of hitting the facial nerve.

Numbness will pass faster if the doctor prescribes UHF or electrophoresis. Also accelerate the recovery of the vitamin complex of the group there Is a list of homeopathic medicines that can accelerate the removal of obesity: Secale cornutum, Viscum and many others.

Good help means with the extract of gingko biloba. From folk methods – horse chestnut, a bark of viburnum, yarrow, primrose. In addition, it is advisable to visit a neurologist or neurostomatologic for the purpose of treatment.

Why there is a loss of sensitivity after removal of the wisdom tooth

In our body, there are 12 pairs of cranial nerves that Innervate the skull, facial muscles, salivary and lacrimal glands, jaws and teeth. Among them, 5 pair is a trigeminal nerve. It is divided into three branches: the orbital, maxillary and mandibular nerve. As the name implies, the maxillary nerve innervates the upper jaw, and the mandible — the lower jaw.

With the surgical removal of the wisdom tooth, the dentist-surgeon can accidentally damage the small branches of the maxillary or mandibular nerve. This causes paresthesia in those areas of the face that innervated these branches. As well paresthesia may appear due to postoperative swelling of the gums, inflammation of the periodontal tissues. In this case, the tissue swells and squeezes the nerve branches, which causes characteristic symptoms.


• HELP Often affects the lip area, the adjacent part of the cheek, chin.
• loss of sensitivity, similar to the action of painkillers;
• numbness;
• the feeling of “pins and needles»;
• burning;
• itch;
• loss of taste sensitivity.

ATTENTION paresthesia is quite common as a complication after tooth extraction. Normally, numbness passes within 1-2 weeks, you can reduce this period with the help of medication and physical therapy. However, if the discomfort continues for more than a month, you should contact your dentist-surgeon.

How to treat paresthesia (numbness) in the mouth

Vitamin therapy

Intake of vitamins B and C promotes healing of postoperative wounds, stimulates the immune and circulatory systems.

To these drugs, there are a number of contraindications:

• diabetes;
• heart failure;
• pregnancy and lactation;
• reduced kidney function;
• heavy bleeding;
• uncontrolled increase in blood pressure;
• gastric or duodenal ulcer;
• childhood;
• hemorrhages in the retina, in the brain;
• severe arrhythmias;
• heart attack.


UHF-ultrahigh frequency therapy. The tissues are affected by an alternating current of ultrahigh frequency. UHF acts in two directions: thermal effect and oscillatory effect. Thermal effect relaxes muscle fibers, improves blood circulation in the affected area.

Oscillatory effect-is the impact on the body at the cellular level, as a result of the cleavage of amino acids from proteins in the place of exposure, creates an acidic environment that helps to resolve the inflammatory process.

Magnetic therapy-the impact of the magnetic field on the human body. As a result, swelling of tissues is reduced, pain is reduced, postoperative wound healing is accelerated, small branches of nerves are restored, blood supply to the affected area is improved.

Electrophoresis-a method of administering drugs through the skin using electrical impulses. When paresthesia is most often prescribed the introduction of vitamins b and C. However, do not forget about the physiotherapy effect of the electric current itself. It reduces inflammation, swelling of tissues, pain syndrome, relaxes muscles, has a calming effect, improves blood circulation, promotes rapid regeneration of damaged tissues.

Surgical treatment

If paresthesia does not pass more than 6 months and does not respond to conservative treatment.
Possible complication

The complication of paresthesia is further nerve damage, despite ongoing medication, physiotherapy, and surgical treatment. As a result, the entire sensitive part of the trigeminal nerve is affected and the person loses sensitivity in some areas of the face forever. Fortunately, this complication is extremely rare. In order to avoid further damage to the nerve, you should consult a doctor if numbness does not pass within 1 month.

Persistent paresthesia. With this disease, there is a chronic course of numbness. As a result, in a normal state, the pain syndrome does not manifest itself, but with hypothermia, trauma, emotional stress, physical overload, the pain resumes, then spontaneously passes a few days later.

Prevention of numbness

Observance of thorough hygiene of the oral cavity. With a negligent attitude to cleaning the surface of the operating wound, an infection can get into it, which will cause inflammation and compression of the branches of the trigeminal nerve.

Careful monitoring of blood pressure figures. With high blood pressure, the walls of the vessels are tense, the vessels expand and can injure the nerve passing between them.

Blood glucose monitoring. Low glucose levels can cause damage to small branches of the trigeminal nerve.
Healthy lifestyle. Compliance with the daily routine, regular exercise, and walks in the fresh air contribute to the stabilization of mental functions and normal activity of the nervous system.
Proper nutrition, excluding the use of canned, spicy, fried, too hot and too cold food. Timely access to a doctor if the symptoms of paresthesia are delayed.

Numbness of the lips, chin, corner of the mouth, part of the cheek after surgical removal of the wisdom tooth is a fairly common complication. In most cases, the sensitivity is restored within 7 -14 days, sometimes up to 1 month. If the sensitivity is not restored in 30 days, you should contact your surgeon-dentist, he will prescribe medication and physiotherapy. After the course of treatment, sensitivity is restored in 98% of patients.

How to treat paresthesia at home?

For the treatment of folk remedies, the patient is obliged to consult a specialist. How to treat paresthesia at home? Some decoction fees can be used to ease the condition and eliminate symptoms:

Take 2 parts of the bark of viburnum, nettle and parsley fruits and mix with violet, sweet clover and grass goldenrod (3 parts). 2 tablespoons collection pour 500 ml of water, boil for 5 minutes, to insist, to drink 1/2 Cup three times a day.

Mix celery root, Valerian and Dubrovnik herbs in 1 tablespoon, pour 600 ml of boiling water, infuse for 2 hours and add honey. Drink 100 ml twice a day.

For home treatment, you can also use horse chestnut or dietary Supplements, including the extract. The good effect gives therapy with yarrow and primrose.

Possible complications of paresthesia

Tooth extraction can lead to common complications: bleeding, inflammation, and swelling of the gums, dryness of the hole, rupture of the bottom of the sinus of the upper jaw, stomatitis, fracture or dislocation of the lower bone of the skull, in the fossa may remain a fragment of the root. The main complication in the absence of paresthesia therapy is nerve damage, which subsequently numbs the skin. The disease may be accompanied by partial or complete loss of sensitivity of large areas of the face forever.

When conducting anesthesia there is a complication in the form of hematoma. The needle damages the blood vessel, causing blood to flow into the surrounding tissue. They are most likely to occur in vascularized regions. More often hematomas are formed with analgesia of the lower jaw.

Preventive measures

Prevention of paresthesia is reduced to the exclusion of factors that can contribute to the loss of sensitivity after surgery:

• refusal to drink alcoholic beverages;
• control of blood sugar levels;
• maintaining a healthy lifestyle;
• compliance with drinking regime;
• tracking changes in blood pressure;
• fractional food (4-6 times a day).

In most cases, the disease is a harmless violation of the functionality of the dental-jaw system, which does not require treatment. In some situations, it may be a sign of a serious chronic disease or organ pathology. If the problem delivers significant discomfort, you should visit a doctor who carries out the removal of the tooth, and then address to the neuropathologist.

Damage to nerve endings

Depends on what that numb lip after tooth removal
1. Damage to nerve endings

A symptom of decreased sensitivity felt as numbness of the lip after removal of the wisdom tooth provoked by damage to the nerve endings refers to complications after surgery. Numbness after removal of the wisdom tooth may be temporary or prolonged. In addition to this reason, there are cases of incorrectly administered anesthesia. To accurately determine the diagnostic case that led to an unpleasant symptom, such as numbness after tooth extraction, a medical examination of the patient is necessary.

The nervous apparatus of chewing elements is associated with the zone of sensitivity of the face and jaw. Therefore, when the damaging effect in the response zone is caused by pain and subsequent lack of signal.

But numbness of the chin after removal of the wisdom tooth is not always, but only in cases of traumatic impact on the sensitivity zone.

2. Depends on what that numb lip after tooth removal

The course of manipulation to extract the root can have such a result, regardless of whether it is carried out correctly or not. It all depends on the location of the nerves that are mutually related to the teeth, especially when the complex extraction of eights (wisdom teeth) takes place.

Difficult access to the inside of the chewing element creates conditions for damage or even grazing sensitive endings. The result is a numbness of the lips after tooth extraction.

The branching sensitive apparatus is located near the root tip. He often gets hurt during surgery. From the zone of its damage depends on the amount of reduction in response and the period of symptomatic manifestation, when after removal of the tooth does not pass numbness.

The branches of the nerve extending from the General part diverge into the zones of the right and left lower jaw. From the fact that they are damaged, there is a numbness of the chin after tooth extraction.

As a result, the phenomenon manifests itself in the form of an uncomfortable and unusual state of the lower face:

• reduction;
• or lack of response to all sorts of stimuli.

With the proper observance of the recommendations for the recovery period, the process itself is allowed, in cases of non-volumetric effects on the nervous apparatus.

In difficult situations, the treatment is supplemented by physiotherapeutic methods, with the internal introduction of b vitamins or after 6-12, in the presence of the presence of an unpleasant condition by surgery.

The level of complexity of operations, recovery period and the probability of complications depend on which jaw wisdom tooth is removed and how it is located.

The eight of the upper jaw rarely have a pathology of development, they are removed more often not for orthopedic indications, but because of the already developed deep caries.

Dentists are against the treatment of such teeth because they are poorly developed and located in an inaccessible place for treatment and cleaning. Extraction of a fully erupted tooth is easy, does not take much time and does not cause serious complications.

Removal of the wisdom tooth of the lower jaw is a traumatic operation, the complexity of which depends on its position. There are fully and partially impacted eights, dystopian, with curved roots in the form of a hook, etc.

The more inaccessible the tooth is, the longer the removal lasts, the more manipulations are performed, the rehabilitation period is worse and the probability of complications is higher. The patient should know what feelings after surgery are normal, and at what it is better to consult a doctor.


A slight increase in temperature to 37 degrees for three days-a normal phenomena after “pulling” the third molar. On the day of removal allowed value of 37.5 degrees, which is reduced by morning.

The gradual decline in temperature along with pain syndrome is a sign of the beginning of wound healing. Accurate diagnosis, when the temperature is a sign of complications of tooth extraction, can be established only by a specialist.

In case of its increase to 38 degrees longer than three days, you should immediately contact your dentist.

High temperature, as a consequence of the elimination of the eight, is manifested if there is:

• inflammatory process;
• allergic reaction;
• the presence of a foreign body in the wound;
• damaged tissue of the jaw;
• alveolitis;
• pinched nerve.


If you remove a correctly placed top eight (sometimes these are and bottom) and the seams do not overlap, then bleeding shouldn’t be.

A clot is formed in the hole, which must remain there. If much blood has gone, it is separated and washed off, which leads to the entry of infection into the wound and inflammation.

After a complicated surgery to remove impacted lower eight during the day is bleeding a little, all depends on the individual characteristics of the patient. Some blood coagulates instantly, others-does do not stop for a long time.

This type of surgery involves suturing the wound, as a large incision is made, from six to the edge of the eight. The blood clot lies under several salts of seams and will not fall out on its own, so you should be afraid only in case of heavy bleeding, the causes of which are:

• hot bath;
• Smoking (which liquefies the blood);
• sharp facial movements (from them it is better to refrain to wound healing);
• physical activity;
• the use of blood-thinning products and drugs.

In complex operations not suture the entire wound, leaving a small hole to drain the ichor. In the first and second day is considered the norm periodic pumping of fresh blood from under the top seam, especially during sleep.

From the third to the seventh day, and in some cases, and on the tenth, there is a moderate branch of ichor from the wound (not the holes) is the norm. Each patient has a different healing period.

What to do?

Although a small bleeding in the early days is the norm, the patient’s task is not to allow its transformation into abundant. Well contribute to blood clotting the following manipulations:

take a vertical position and apply to the wound a cold object from the freezer, for example, a pack of oil, through a waffle towel.

Do not press, the pack should barely touch the jaw. A little hold and give a rest to prevent frostbite and not to stiffen the throat. So to repeat until weakening bleeding.
dilute 3% hydrogen peroxide with cold boiled water in a ratio of 1: 1. Pour on the side of the wound and hold for a few seconds, then gently drain. Do not rinse or spit with force. Peroxide promotes coagulability and additionally has an antiseptic effect.

Buy in the pharmacy nettle grass in bags, prepare a concentrated infusion (according to the instructions), cool, slightly squeeze the bag, put it in place and tightly press the teeth.

It is important that the wound was sewn to the open hole after the usual removal is not applied. This method is best not to use unless absolutely necessary because non-sterile bag can bring infection.

Help with severe bleeding

If bleeding profusely and it was obvious that something went wrong, you need to call an ambulance or on their own (if not far to go) to go to the E. R. the maxillofacial Department, which is in every major hospital and operates around the clock.

There are times when neither is possible. In such a desperate situation, in addition to local methods of assistance, you need to take drugs inside. One of the following:

1. cold concentrated infusion of nettle, start with 1 tablespoon, if not helped, continue to drink.
2. Vicasol or any antihemorrhagic agent that promotes blood clotting.

Alveolitis is a dangerous complication after the removal of the wisdom tooth when the open wound becomes infected and inflamed. It manifests itself on 3-4 days after surgery. If left untreated, a few days later develops into the osteomyelitis-the defeat of the jaw bone.

What to do during the day after surgery?

In the wound, a tampon with hemostatic and antiseptic action is laid. You need to get it out after a period of time recommended by the doctor. Usually, it is from 5 to 20 minutes.

To reduce future edema, on the way home from the clinic, attach a cooling package to the cheek chill (sold at the pharmacy, costs about 10 rubles). The fact is that it is better to start cooling the sore spot as soon as possible.
On the first day, it is mandatory to take non-steroidal anti-inflammatory drugs. Many surgeons recommend drinking Nise before beginning to move away anesthesia.

Do not expose yourself to stress and physical activity, recommended bed rest.
On the first day to use only liquid food (not even porridge).
After each meal, make baths of the oral cavity with a salt solution to wash out the remnants of food and sanation of the wound, and then infusion of chamomile, which relieves inflammation.

In the mouth is typed in the appropriate solution and kept for a certain time. Rinsing is prohibited as it may damage the clot on the wound or cause bleeding.

Recommendations on nutrition for the entire period of rehabilitation. Such a diet is observed to have the stitches removed and a few days after:

All dishes should be passed through a blender and have a mushy consistency. It is impossible to make chewing movements, it will lead to divergence of seams and deterioration of rehabilitation.
1. Food should be at room temperature.
2. Spicy foods and spices are prohibited.
3. It is necessary to choose a high-calorie and most useful diet, because during this period the body needs strength, if a week to drink one kefir, healing will be delayed.
4. No drinking.

Paresthesia after tooth extraction

The operation to remove the “wise” organ is quite painful for a person, despite the use of local anesthesia. Patients often tell the dentist 1-2 days after the procedure that they do not feel parts of the jaw, tongue, cheek. Paresthesia after pulling the wisdom tooth manifests itself as a symptom of a failure of the internal systems of the body and indicates the problem that caused it. Nerve impulses between the Central nervous system and a particular organ give different signals, and the body does not understand how to react to them.

The loss of susceptibility may extend to one or both sides of the dentition. The degree of violations can be mild or severe, the possibility of pain related to neurological problems is not excluded.

Causes of occurrence

Complications with the use of local anesthesia occur most often through the fault of the doctor. When manipulating it touches the nerve of the lower bone of the skull. This happens when the nerve is close to the tooth or the root has an abnormal slope, which is why it is required in most cases to perform the removal of the unit. Paresthesia occurs for a number of other reasons:

• profuse bleeding;
• severe pain after surgery;
• General swelling of the gums;
• a wrong arrangement of the eight (especially in the bottom row);
• specialist grazing of the lingual nerve.

After the extraction of the organ, the loss of susceptibility to palpation is noted in 7% of cases, most often elderly people and women complain about it. The tendency to the disease is in some groups of patients suffering from different pathologies:

• oncology;
• osteochondrosis;
• disorders of the cardiovascular system;
• neurological disease;
• poisoning of the body and dysfunction of the endocrine system;
• diabetes;
• problems of the gastrointestinal tract;
• incorrect functioning of ENT organs;
• a common deficiency.


When the wisdom tooth is removed, many patients note that the sensitivity of certain areas of the face has disappeared. If the sensations do not disappear within a few days, then paresthesia is diagnosed. The presence of the disease is determined by the following symptoms:

• tongue and lip numbness;
• changes in taste reactions;
• itching or tingling in the chin area;
• frequent salivation;
• deformation of facial expressions;
• involuntary lip biting, tongue biting;
• the absence of paralysis.

The feelings of each person with local anesthesia are different. In some patients, tissue immunity persists for a long time, affecting the organs of the front part of the body completely or their individual parts. Other patients complain of discomfort only in the lower part of the face, including the chin. This causes discomfort, but it can be eliminated.


If the specialist touched the nerve, it will be restored in the patient for 1-2 weeks. To speed up the process, the doctor prescribes special procedures. When the problem bothers a person for a month or longer, the dentist can prescribe drugs and direct the patient to physiotherapy. Also, the patient should consult a neurologist or neurostomatologic. A tingling feeling is the first sign that the body’s functions are beginning to return to normal.

A radical solution to the problem is surgery. The operation is performed by a maxillofacial surgeon but is performed only in cases where tissue susceptibility has not recovered after 1-2 years.
