Why is wisdom tooth removal necessary?
1.Sinus Issues: Problems with wisdom teeth can lead to sinus pain, pressure, and congestion.
2.Damage to other teeth: That extra set of molars can push your other teeth around, causing jaw pain,and crowding of teeth.
3.Jaw damage: Cysts can form around the new teeth. If they aren't treated, they can hollow out your jaw and cause nerve damage.
4.Inflamed Gums: Tissue around the area can swell and may be hard to clean.
5.Cavities: Swollen gums can create pockets between teeth that help bacteria grow and cavities form.
6.Alignment: Impacted wisdom teeth can cause problems with crowding of other teeth and even make treatment to straighten other teeth necessary.
Evaluation of your wisdom teeth will be done upon your initial exam. Depending on the severity of impaction, your extraction is planned.
If the lower wisdom teeth are partially erupted but there is no sign of any decay or gum infection. Adjacent teeth are also healthy and intact. However, the x-rays showed that the roots of her wisdom teeth are tightly pressed against the nerve in the lower jaw. This nerve provides sensation to the lips and surgery to remove her lower wisdom teeth will carry a high risk of injury to the nerve which may, in the worst case scenario, result in a permanent numbness of the lower lips. As such, I recommended that leave the wisdom teeth alone and only remove them if they cause trouble.
The next option is not very commonly done but is a viable option for cases where the wisdom tooth is very close to the nerve and is painful. The crown can be cut off, leaving the root in the bone. This procedure, known as coronectomy, is gaining in popularity as the complication rate was found to be low. A study following 612 wisdom teeth that underwent coronectomy over five years found a complication rate of less than 1%. For patients with wisdom teeth that are pressed against the nerve, coronectomy is a viable option.
