What You Need to Know About Wisdom Tooth Extraction and Impacted Wisdom Teeth

Wisdom tooth extraction is a common dental procedure that involves removing the third molars, commonly known as wisdom teeth. These teeth sit at the very back of the mouth, with two in each jaw for a total of four. When there isn't enough space, misalignment or impaction often results.

Due to lack of space, wisdom teeth can cause pain, infection and damage to neighboring teeth; because they're hard to clean, the risk of periodontal disease also increases. Misalignment, chronic infection or orthodontic treatment plans are the main reasons extraction becomes necessary. Symptoms include pain, swelling and tenderness in the gum area, and difficulty opening the mouth.

Diagnosis is made through a clinical exam and a panoramic X-ray. Extraction is performed under local anesthesia with specialized instruments; impacted teeth may require cutting the gum and bone. Pain management and infection-prevention instructions are given afterward.

An impacted wisdom tooth is one that fails to reach its normal position and remains within the jawbone or under the gum, usually due to insufficient space. This can lead to pain, inflammation and pressure on the roots of neighboring teeth. The extraction process includes a detailed exam, X-ray, local anesthesia, surgery and recovery care; being more complex, it should be performed by experienced practitioners.

After extraction, pain management, oral hygiene and follow-up visits are key parts of recovery. General anesthesia may be preferred in complex cases; leftover root fragments can cause infection or pain and may require additional surgery, and larger incisions may need stitches. Even a painless wisdom tooth may be recommended for removal to prevent future problems.
