Infection: Most are minor and will subside with local incision and drainage, and antibiotics. The whole course of antibiotics should be completed.
Tooth root fracture: The roots may be retrieved or left in situ. The dentist may decide to leave the root in situ if there is no pathology or if the root is very close to the nerve or at an unfavourable anatomical site.
Dry socket: This occurs when blood clot is dislodged from the extraction site and bone is exposed in the early healing stage. It is usually seen in women on oral contraceptive pills and smokers. If you experience a constant throbbing pain that lasts for many days, contact the dentist.
Numbness or altered sensation: An impacted lower wisdom tooth may be close to the nerve. When the nerve is injured during extraction, it will usually heal. Bruising of the nerve may cause numbness, tingling and loss of feeling in teeth, lips, cheeks, tongue, chin and gum and it may be temporary or permanent.
Displaced tooth: In some cases, an impacted tooth may be displaced into the sinus and the different spaces around the jaw.
