1. Persistent Sores That Won’t Heal
We all get canker sores or bite our tongues occasionally. These usually heal within 7–10 days.
The Warning Sign: A sore, ulcer, or irritation on the lip, tongue, or inside of the mouth that does not heal after two weeks.
What to look for: A crater-like spot that might have a red or white border. It may bleed easily when touched.
2. Red or White Patches (Leukoplakia and Erythroplakia)
Changes in the color of the soft tissues in your mouth are significant indicators.
Leukoplakia: Thickened, white patches that cannot be scraped off. While often benign, some can be precancerous.
Erythroplakia: Flat, bright red patches. These are less common but have a higher likelihood of being precancerous or cancerous than white patches.
Mixed Patches: Some areas may have both red and white speckling (erythroleukoplakia).
3. Lumps, Thickenings, or Rough Spots
Run your tongue along the inside of your cheeks, gums, and under your tongue.
The Warning Sign: Any lump, bump, crusty area, or rough spot that feels different from the surrounding tissue.
What to look for: A hard mass on the jawbone or a thickening of the cheek tissue. It might feel like a small pea under the skin.
4. Unexplained Bleeding
Bleeding gums are often associated with gingivitis, but spontaneous bleeding without brushing or flossing can be a sign of something more serious.
The Warning Sign: Bleeding in the mouth that occurs without an obvious cause (like aggressive brushing or a known injury).
