Swollen gums Gum disease
Swollen gums are inflamed gums. Swelling all along the gumline usually means gingivitis; a swollen bump at one tooth is often a periodontal abscess or trapped food. Pregnancy, some medications and poorly fitting dental work also cause swelling. Swelling with pain, pus or fever needs a same-day visit.

What makes one spot swell?
A swollen bump beside one tooth is commonly a periodontal abscess: bacteria trapped in a deep pocket. It can drain and seem better, but returns until the pocket is treated. Gum pain and abscess.
How are swollen gums treated?
- Cleaning and daily brushing and flossing for gingivitis.
- Drainage and pocket treatment for an abscess.
- Medication review with the prescribing physician for drug-related overgrowth.
- Gum reshaping, often by laser, for overgrowth that remains.
Questions
Can swollen gums go down on their own?
