A dental infection may arise within a tooth, around its root, in a periodontal pocket, or in tissues around a partially erupted tooth. Pain, swelling, discharge, a bad taste, or tenderness can occur, but not every toothache is an infection and not every infection produces the same symptoms. An abscess is a localized collection of pus; infection-related concerns can also exist without an obvious visible collection.
Assessment identifies the source, checks whether the problem is spreading, and considers your medical history. Treatment may involve a tooth-preserving procedure, drainage, periodontal care, or extraction when appropriate. Antibiotics have a role in selected situations, but they do not replace the dental treatment needed to address the source. Rapidly spreading facial or neck swelling, breathing or swallowing difficulty, or serious illness requires urgent medical assessment rather than waiting for a routine dental visit.
