FAQ
Pain & SymptomsWhy Is My Gum Swollen Around One Tooth?
Quick Answer
Swelling around a single tooth is usually caused by a dental abscess, gum infection, or food trapped under the gum. See a dentist promptly — especially if you have pain or fever.
Detailed Explanation
Localized gum swelling around one tooth has several causes. A periapical abscess (infection at the tooth root) causes swelling at the gum near the affected tooth. A periodontal abscess (gum infection) creates a painful swelling in the gum tissue. Food or debris trapped under the gum can cause localized inflammation. A cracked tooth can allow bacteria to enter and cause infection. In all cases, the swelling indicates an active infection that requires professional treatment. Do not attempt to drain the swelling yourself. Rinse with warm salt water for temporary relief and see a dentist as soon as possible. Antibiotics alone will not resolve a dental abscess — the source of infection must be treated.
