White pimple on gum above tooth
A white pimple on the gum above a tooth can be a draining dental abscess, although irritation or a harmless tissue change is also possible.
The short answer
A white pimple on the gum above a tooth may be a sinus tract draining infection from the tooth root, so it should be examined even if pain is mild. Other possibilities include a traumatic ulcer, blocked gland, or local gum irritation.
How can an infected tooth form a gum opening?
A dental abscess can create pus and pressure around the root apex, then drain through bone and gum into a small opening called a sinus tract. The involved tooth may be tender, discoloured, cracked, or previously filled, but symptoms vary.
What should you do about a white gum pimple?
Do not squeeze, puncture, or repeatedly press the spot. Rinse gently, keep brushing around it, and arrange an examination; the dentist may test the tooth, inspect the gum, and take a dental X-ray before treating the source.
When is a white gum pimple urgent?
Seek prompt care for toothache, swelling, fever, a bad taste, facial swelling, or difficulty opening the mouth. Breathing or swallowing difficulty is an emergency because infection can spread into deeper tissues.
What should you ask about the gum sinus tract?
Ask which tooth is causing the tract, whether the pulp is infected, and whether treatment involves root canal treatment, extraction, or drainage. Ask how the tooth will be restored after infection control.
Frequently asked questions
Can an abscess pimple disappear?
It may drain and flatten while the infection remains, so disappearance does not prove the tooth is cured.
Will antibiotics fix the tooth?
Antibiotics may be used in selected spreading infections, but the dental source usually needs specific treatment.
