I Have a Red Velvety Patch in My Mouth — Is That Bad?

I Have a Red Velvety Patch in My Mouth — Is That Bad?

A red, velvety patch in the mouth is less common than white patches, and it needs more attention. Here is why.

A red, velvety patch in the mouth is called erythroplakia. Unlike white patches (leukoplakia), erythroplakia is less common but has a higher chance of containing abnormal or precancerous cells. This does not mean it is cancer, but it is a finding that should never be ignored.

• Possible causes include:
• Erythroplakia — a red patch that cannot be explained by injury or inflammation; about 50–70% of these show abnormal cells when biopsied
• Inflammatory conditions — lichen planus, geographic tongue, or allergic reactions can cause red areas
• Fungal infection — thrush can sometimes appear red instead of white
• Trauma — burn from hot food or irritation
• Hemangioma — a benign collection of blood vessels that looks reddish

What to Look For

• Usually not serious:
• Red area that appeared after eating hot or acidic food
• Heals within a few days
• Red patches that move or change location (like geographic tongue)
• Clearly related to an injury or burn

• Worth having checked:
• A red, velvety patch that does not go away after 2 weeks
• Patch with a mixed red-and-white appearance
• No clear cause (you did not burn or injure the area)
• Patch that bleeds easily when touched
• Area that feels slightly raised or different from surrounding tissue

When to See a Doctor

• See a dentist or ENT doctor promptly if:
• You notice a red, velvety patch with no clear cause
• The patch lasts more than 2 weeks
• It has a mixed red-and-white appearance
• It bleeds when you touch it
• You smoke, drink heavily, or have other risk factors
