Gum pimple or bump causes and treatment
A pimple-like gum bump may be a draining dental abscess, an irritated tissue tag, a cyst, or another lesion, and squeezing it can worsen injury.
The short answer
A pimple-like gum bump may be a draining dental abscess, an irritated tissue tag, a cyst, or another lesion, and squeezing it can worsen injury. Other possibilities include a periodontal abscess, irritation, a blocked minor salivary gland, cystic tissue, or a benign growth.
How can an infected tooth create a gum pimple?
A tooth-root infection can create pressure in bone and drain through the gum, producing a pimple that may release fluid while the tooth remains painful or even feels better. A gum abscess usually starts in the tissues beside a tooth and may be associated with a deep pocket, food trapping, or calculus.
What should you do with a pimple-like gum bump?
Do not pop, cut, or repeatedly press the bump. Keep the area clean with gentle brushing, rinse with lukewarm salt water if comfortable, and arrange an examination; the dentist may trace the tooth, test pulp vitality, probe the gum, and take dental imaging.
When is a gum bump an urgent dental problem?
Seek urgent care for spreading swelling, fever, severe pain, difficulty opening the mouth, swallowing, or breathing. Any bump that persists, enlarges, ulcerates, or bleeds needs assessment even without tooth pain.
What should you ask about the cause of a gum bump?
Ask whether the bump drains an infected tooth or gum pocket, whether imaging is needed, and whether treatment involves drainage, root canal treatment, periodontal care, extraction, or observation.
