I filled my tooth last year but every time theres little pain i feel, theres also something developing on my gum closer to the tooth on the top ?

Dentist can check: The gums around a tooth can get inflamed, called gingivitis. A dental cleaning can help. If there is a swelling or lump, there might be an abscess too. One's regular dentist can figure out what's going on. An online video consultation won't solve this issue; in-person dental care is needed.

Unclear: You may have a developing abscess, a high filling, a fracture, a gum infection problem. Please return to your Dentist for reevaluation.
