What should you know about gingival oral lichen planus?

[Lichen Planus](/conditions/lichen-planus/) is an inflammatory condition that can affect skin, nails, and the lining of the mouth. On the gums, it may cause white lace-like lines, redness, peeling, tenderness, or burning with spicy, acidic, or rough foods. Some people also have cheek or tongue involvement. Skin disease may cause [Itchy Skin](/symptoms/itchy-skin/) or [Skin Bumps](/symptoms/skin-bumps/), but mouth findings can occur without obvious skin changes. Similar gum soreness can also come from infection, allergy, trauma, or medication reactions, so appearance alone is not enough for diagnosis.

Use a soft toothbrush and gentle, non-abrasive toothpaste. Avoid tobacco, alcohol-containing mouthwash, and foods that repeatedly trigger burning. Keep dental appointments so plaque, gum health, and any persistent sore area can be checked. A clinician may prescribe [Topical Corticosteroids](/treatments/medical-dermatology/topical-corticosteroids/) applied inside the mouth; more extensive disease may prompt discussion of [Oral Corticosteroid Treatment](/treatments/medical-dermatology/oral-corticosteroid-therapy/). Use prescribed medicine exactly as directed and report thrush-like coating or worsening pain.

Arrange review for gum peeling, bleeding, persistent soreness, difficulty eating, or symptoms that do not settle. Seek prompt dental or medical assessment for an ulcer, lump, thickened patch, unexplained bleeding, or a mouth area that changes or fails to heal. Urgent help is appropriate if swelling affects swallowing or breathing.

Could the gum pattern be oral lichen planus or another condition? Is a mouth examination or biopsy needed? How should I apply treatment around brushing and meals? Do my medicines or dental products need review?
