Keloid on tongue piercing: what to know

Keloids are firm overgrown scars that extend beyond the original injury, but they are less straightforward to identify inside the mouth. A tongue-piercing swelling may instead be mechanical irritation, a local infection, a fluid-filled lesion, or a scar that remains within the piercing channel. Pain, heat, pus, foul taste, spreading redness, or fever raise concern for infection. Jewellery can rub against teeth and gums, and swelling can change how it sits. A healthcare professional should examine the tongue, piercing tract, and nearby mouth tissues.

Avoid touching or rotating the jewellery, smoking, alcohol-based mouth products, and foods that clearly worsen irritation. Follow professional piercing aftercare and keep oral hygiene gentle. Do not pop, cut, or inject the bump. If a clinician confirms abnormal scar tissue, possible options include a carefully selected steroid injection, cryotherapy, laser treatment, or surgery; treatment inside the mouth needs particular planning. See [Steroid Injection Into The Skin](/treatments/injectables/intralesional-steroid-injection/) and [Keloid Removal Surgery](/treatments/surgical-dermatology/keloid-excision/).

Get same-day medical advice for increasing tongue swelling, pus, fever, worsening pain, or difficulty eating and drinking. Seek emergency help for trouble breathing, inability to swallow saliva, rapidly enlarging swelling, or a muffled voice. These signs can reflect a serious oral infection or airway problem and should not be managed by waiting for a scar diagnosis.

Ask whether the swelling is scar tissue or infection, whether the jewellery should remain, how treatment could affect teeth and speech, and which symptoms require emergency help.
