Ulcer on gum above tooth
An ulcer above a tooth may be trauma, a mouth ulcer, or a draining dental infection, so its duration and nearby tooth symptoms matter.
What could an ulcer above your tooth indicate?
An ulcer above a tooth may be trauma, a mouth ulcer, or a draining dental infection, so its duration and nearby tooth symptoms matter.
What tissues are found in the gum above a tooth?
The gum above a tooth contains attached gum tissue over the tooth root and supporting bone. A shallow sore with a white or yellow centre can follow biting or brushing trauma, while a pimple-like swelling that releases fluid may be connected to infection around the root or gum pocket.
How can you care for an ulcer on the gum?
Keep the area clean with gentle brushing and rinse with plain water or a mild salt-water rinse. Do not pop, pierce, or burn the lesion, and avoid foods that repeatedly rub it; note its size, pain, discharge, and how long it has been present.
When should a dentist examine an ulcer above a tooth?
Arrange dental care for a sore that persists, returns in the same place, enlarges, or is linked with toothache, pain on biting, bad taste, or facial swelling. Seek emergency medical care if swelling affects breathing or swallowing or spreads quickly.
What should you ask about a sore above your tooth?
Ask whether the lesion looks traumatic, ulcerative, or related to a tooth root or gum pocket. Ask whether vitality testing, periodontal measurements, or a periapical X-ray is appropriate and what treatment will remove the underlying cause.
Frequently asked questions
Is a gum ulcer always an abscess?
No. Trauma and ordinary mouth ulcers can look different from a draining infection, so examination is needed when the cause is unclear.
Can a cavity cause a sore above the tooth?
Deep decay can allow infection to reach the pulp and tissues near the root, which may produce swelling or drainage on the gum.
