–Procedures on surgical extraction of impacted wisdom tooth :
It has to take balance between the risks and benefits of the surgical extraction of tooth. In some cases, the impacted wisdom tooth is deeply embedded in the jaw bone and its roots are close to main nerve, surgical extraction may impose risk of damaging the nerve, leading to numbness of the mouth. Therefore, the decision on removal or not or when to remove the wisdom tooth is dependent on clinical situation.
The dentist will take radiographs to confirm the position and shape of the wisdom tooth, and explain to the patient on the situation, procedures and any risks. Usually, the procedures will be done under local anesthesia (numbness of mouth only), but in some cases, it may be done under general anesthesia or under sedation. The procedures should be painless.
There are five main steps:
- Raise the gum flap
- Remove the covering bone
- If needed, cut the tooth into few parts
- Rinse and clean the wound
- Close the wound with sutures, and stop the bleeding
One week after extraction, remove the sutures by the dentist who will check the healing of the wound. If the suture is of self dissolve type, then it is not necessary to remove the sutures by the dentist. However, it is still necessary to let the dentist to check the healing of the wound. In general, the wound will heal within 2 weeks.
