What is the direct answer?

What does this question mean?

A single-tooth swelling is different from generalized gum redness because the nearby tooth, root, filling, or pocket may be involved. A small draining bump can be the outlet of an abscess even when pain is limited.

What can you do next?

Clean gently around the tooth with a soft brush and interdental cleaner, avoid squeezing the lump, and note tooth sensitivity, bite pain, discharge, or recent dental work. Arrange an examination so the dentist can test the tooth and measure the surrounding gum.

When should you seek dental care?

Seek prompt care for worsening swelling, spontaneous pain, pain on biting, pus, fever, or facial swelling. Breathing or swallowing difficulty and swelling near the eye require urgent attention.

What should you ask the dentist?

Ask whether the swelling is caused by the gum margin, a periodontal pocket, decay, or the root canal system. Ask whether probing, a vitality test, or an X-ray will guide treatment.

Frequently asked questions

Can trapped food cause a lump above one tooth?

Yes, repeated food impaction can inflame the gum, but a persistent lump needs evaluation for decay or infection.

Will salt water remove the swelling?

A gentle rinse may soothe irritated tissue, but it cannot remove calculus, decay, or infection inside a tooth.
