Wisdom Teeth Removal (Extractions)
Third molars, commonly referred to as wisdom teeth, are usually the last four of 32 teeth to erupt in the mouth, generally making their appearance between the ages of 17 to 21. They are located at the back of the mouth (top and bottom), near the entrance to the throat. The term “wisdom” stems from the idea that the molars surface at a time typically associated with increased maturity or “wisdom”.
Reasons to remove wisdom teeth
While not all wisdom teeth require removal, wisdom teeth extractions are most often performed because of an active problem such as pain, swelling, decay or infection, or as a preventative measure to avoid serious problems in the future. If impaction of one or more wisdom teeth is present and left untreated, a number of potentially harmful outcomes can occur, including:
- Damage to nearby teeth: Second molars (the teeth directly in front of the wisdom teeth) can be adversely affected by impacted wisdom teeth, resulting in tooth decay (cavities), periodontal disease (gum disease) and possible bone loss.
- Disease: Although uncommon, cysts and tumors can occur in the areas surrounding impacted wisdom teeth.
- Infection: Bacteria and food can become trapped under the gum tissue, resulting in an infection. The infection can cause considerable pain and danger.
- Tooth Crowding: It has been theorized that impacted wisdom teeth can put pressure on other teeth and cause them to become misaligned (crowded or twisted). This theory isn’t universally accepted by all dental professionals, and it has never been validated by any scientific studies.
Wisdom teeth examination
As with any dental procedure, your dentist will want to initially conduct a thorough examination of the wisdom and surrounding teeth. Panoramic or digital X-rays will be taken in order for your dentist to evaluate the position of the wisdom teeth and determine if a current problem exists, or the likelihood of any potential future problems. The X-rays can also show additional risk factors, such as deterioration or decay of nearby teeth. Early evaluation and treatment (typically in the mid-teen years) are recommended in order to identify potential problems and to improve the results for patients requiring wisdom teeth extractions.
Only after a thorough examination can your dentist provide you with the best options for your particular case.
What does the removal of wisdom teeth involve?
Wisdom teeth removal is a common procedure, commonly performed under local anesthesia. Intravenous (IV) sedation, or general anesthesia by an oral surgeon in an office surgery suite may be required for removal of impacted teeth. The surgery does not require an overnight stay, and you will be released with post-operative instructions and medication (if necessary), to help manage any swelling or discomfort.
