Reason for pain

tooth extractionindicates certainty, emphasis, etc.The wound may cause pain.The following is a list of the most common problems with the

In the extraction of easy-to-extract teeth, the wound is small and does not damage the tissue much,

The patient often feels no pain after the anesthesia wears off.

But for teeth that are hard to pull out,

This is because cutting the gums with a scalpel or cutting between the teeth and bone also increases the probability of tissue damage,

Pain often occurs after the anesthesia wears off.


During the extraction, though, the patient will not feel any pain because of the anesthesia,

After tooth extraction, pain may occur gradually as the anesthesia wears off.

Anesthesia dosage and duration of effect


By anesthesia due to tooth extraction,

The duration of anesthesia is approximately 1 hour and 30 minutes for a short person.

For the longest person, it is about 4 to 5 hours.

However, the duration of anesthesia depends on the amount of anesthesia administered and the patient's constitution.

When extracting a tooth that is wobbly or decayed and ragged,

The amount of anesthesia is almost the same as that used to treat normal tooth decay and periodontal disease.


Is there a lot of anesthesia for wisdom teeth extraction?


Like buried in the gums.When wisdom teeth are extracted, 1.5 to 2 times the normal amount of anesthesia is required.

In addition, people with hard or thick bones have difficulty with anesthesia,Inevitably, the amount of anesthesia will be higher.

The higher the dose of anesthesia, the longer the anesthesia generally remains in effect.


It is difficult to predict the magnitude and duration of post-extraction pain, though,

It is possible to take measures to prevent as much pain as possible.

Pain due to infection

5121498 s

Reason for pain

Minor oral surgery, not limited to tooth extractions, is bound to cause infection to a greater or lesser degree because the wound is contaminated with saliva.

This is because there are many bacteria in saliva.

When infection occurs, the patient's own immune system first resists the infection, but antibiotics further suppress the infection.

However, if the inflammation becomes larger than expected, it cannot be handled by one's own immune system or antibiotics.

This causes symptoms of pain and swelling.


Antibiotics are always prescribed when a tooth is extracted.

If the pain becomes worse (more severe)

In the case of mandibular extraction

Inflammation spreads from around the mandible to the throat,

In the worst case, inflammation can spread to the mediastinum (the space surrounded by the left and right lungs where the heart and other organs reside).

For extraction of maxillary teeth

It can spread from the maxillary sinus to the orbit (under the eye) and in the worst case, to the brain. (cellulitis)


The antibiotic may be changed to a stronger antibiotic or, in some cases, administered intravenously.

This is because it is more effective to have antibiotics in the body by intravenous infusion.

And in the worst case, inpatient management may be required.

How to prevent pain caused by infection

To prevent the infection from becoming severe.

People with low immunity or who have systemic diseases that put them at high risk of infection, such as diabetes mellitus,

It is recommended that prophylactic administration of antibiotics be given prior to tooth extraction to increase the blood level of antibiotics before extraction.

Potential for pain not only in the teeth, but also in the entire mouth, including gums and tongueThere are


Neuropathic pain is especially likely to occur after wisdom tooth extraction in the mandible.

Drug Therapy

Vitamins, steroids, ATP preparations, and herbal medicines

Block injection

Treatment aimed at relieving symptoms by blocking the stellate ganglion

Nerve suture surgery

Indicated when nerves are completely torn, for example


To reduce the probability of developing neuropathic pain,

CT scan before tooth extractionto determine the location of the roots and nerves of the teeth in three dimensions.

It is recommended that the tooth be extracted.


Because extraction is a surgical procedure, the postoperative period may be painful.

In the case of simple tooth extraction, though, it may not be accompanied by pain,

The possibility of pain is increased in the case of extraction of hard-to-remove teeth.

If pain occurs, it usually settles down in a few days,

Pain may be prolonged if infection, impaired blood flow, or neuropathic pain occurs.
