A wisdom tooth can become uncomfortable when surrounding tissues are inflamed, when decay affects the tooth, or when another problem develops nearby. Food trapping around a partly erupted tooth may contribute, but a painful second molar, a jaw problem, or another condition can feel similar. The location of the pain is a starting point for assessment rather than proof of the diagnosis.
Treatment addresses the immediate cause and considers whether the problem is likely to recur. Some situations need local care and review; others lead to a discussion about extraction or referral. Antibiotics are not automatically the first or only treatment for every painful wisdom tooth. Swelling, difficulty opening, and general illness affect urgency, while breathing or swallowing difficulty or rapidly spreading swelling requires urgent medical assessment.
