Wisdom Teeth Impaction and Oral Surgery


Dentist Finder

Certain dental procedures such as those needed in cases of wisdom teeth impactions cannot be entirely avoided. However, these procedures are undertaken using local and general anesthesia to ensure ease and comfort.

This article explains different types of teeth impactions, how surgical procedures can be used to rectify each situation and what to expect before, during and after surgery.

Wisdom teeth

The third molars, popularly known as wisdom teeth, appear between the ages of 16 and 24. In many cases they need to be taken out because the size of the jaw is not enough to hold extra molars.

Discrepancies such as hypodontia and supernumerary wisdom teeth can occur in the development of wisdom teeth.

Hypodontia is a condition in which the wisdom teeth are missing due to their failure to develop.

A supernumary tooth is an extra tooth that develops in addition to the normal 32. Extra teeth can cause crowding and lead to poor oral hygiene.

Teeth impactions

Impacted wisdom teeth can be of a number of types, depending on how they develop out of the gum line, relative to normal teeth.

Mesioangular impaction, where the tooth is angled forward, is the most common type of wisdom teeth impaction.

Vertical impaction happens when the formed tooth does not fully erupt (or emerge) though the gum line.

Distoangular impaction happens when the tooth angles backwards.

Horizontal impaction occurs when the tooth develops at a full 90 degree angle forward. It develops sideways rather than normally upward.

Each type causes its own associated problems. But all of these can be rectified by oral surgery.

Bony impaction vs. soft tissue impaction

Impactions can also be divided into two categories depending on their location.

Bony impaction occurs when the wisdom teeth are housed in the jawbone, rather than in the soft tissue of the gums.

Soft tissue impaction occurs when eruption of wisdom teeth happens outside the jawbone, but without coming out of the gum line.

Operculum and treatment

At times, wisdom tooth does not erupt fully though the gums. It creates an extension of soft tissue of the gum over the biting surface of the tooth, called an operculum. The operculum can get irritated while chewing on food and become infected leading to pericoronitis. This condition causes intense pain, swelling, redness and gives out a bad smell. It also makes it difficult to open the mouth.

Teeth covered with operculum are hard to clean with regular brushing. They are best cleaned using cleaning techniques available at a dental clinic.

If the operculum cannot be taken out, extraction of the wisdom tooth is recommended. The other option is a treatment called operculectomy to remove the operculum. But, it is a risky procedure and is not a recommended treatment anymore in oral surgery.

Before tooth impaction surgery

As pre-operational procedure, the oral surgeon would examine the X-rays taken by the dentist. He would then carry out a physical examination of the mouth to feel the impacted tooth. If the oral surgeon feels that infection is present in the tooth, he would recommend immediate treatment. If he feels that the case of the impacted tooth is not an emergency case, he may plan the operation to fit the schedule of the patient.

Surgical procedures

Oral surgery can be done in a dental clinic or in the hospital under general anesthesia. This depends upon whether the wisdom tooth is impacted or not.

The surgery will involve making a cut in the gum to reach the impacted wisdom tooth. On normal situations, the surgeon may just use dental tools to remove the impacted tooth. In some cases, surgery may involve removing pieces of the jaw. The gum will then will be stitched up and gauze used to pack the area to reduce bleeding. The surgery could take anything between one to four hours, depending on complexity of impaction.

After tooth impaction surgery

After the tooth is removed, you will most likely be asked to bite down softly on a piece of gauze for 30 to 45 minutes to limit bleeding. You can expect some pain and swelling, but it will usually subside in a few days. If there is prolonged swelling, severe pain, bleeding or fever, you should call your dentist.
