Gum overgrowth around tooth causes evaluation and treatment options
Gum tissue growing around a tooth can reflect plaque inflammation, eruption changes, irritation, medication effects, or another lesion.
The short answer
Gum tissue growing around a tooth can reflect plaque inflammation, eruption changes, irritation, medication effects, or another lesion. The cause cannot be identified from appearance alone, so the tooth, gum pocket, bite, and nearby tissues need examination.
How might enlarged gingiva appear around a tooth crown?
The gingiva may look enlarged, rounded, red, or folded over part of the crown. A partially erupted tooth, trapped food, orthodontic appliance, rough restoration, or chronic plaque can keep the tissue irritated.
What can you do safely while arranging a gum examination?
Clean gently with a soft brush and an appropriately sized interdental tool, and avoid cutting, burning, or squeezing the tissue. Note when it appeared, whether it bleeds, and whether a tooth is erupting or painful.
When does swelling around a tooth need dental assessment?
Arrange care for a growing, painful, bleeding, ulcerated, firm, or persistent swelling, especially with pus, bad taste, fever, or a loose tooth. Rapid facial swelling or difficulty swallowing or breathing needs urgent attention.
What should you ask about the cause of the tissue growth?
Ask whether the tissue is inflamed gum, an eruption flap, medication-related enlargement, or a separate growth. Ask whether cleaning, an X-ray, gum treatment, removal of excess tissue, or referral is appropriate.
Frequently asked questions
Can swollen gum grow back over a tooth?
It can partly cover a tooth when inflammation or eruption changes enlarge the tissue, but the cause must be checked before treatment.
Will better brushing remove the overgrowth?
Cleaning may reduce plaque-related swelling, but calculus, an eruption flap, medication effect, or a separate lesion needs professional management.
