Can cheek biting cause cancer?

Accidental cheek biting won't cause cancer, but chronic, repeated biting can cause long-term irritation to the inner lining of your mouth. Try to avoid very spicy or highly acidic foods when you have a fresh bite wound, as it delays the healing process.

If accidental cheek biting caused cancer, half of us would be in trouble by now! I bite my cheek every time I try to talk and eat samosas at the same time. Don't worry, it's just a temporary ulcer, it will heal on its own.

I agree with the others, normal cheek biting does not cause cancer. If you have a sharp tooth causing constant cuts, just get it filed by a dentist.

Beta, in all my years, I have seen so many people panic over this. A simple cut from biting your cheek is completely harmless and does not lead to cancer. Just rinse your mouth with warm salt water, it will heal beautifully in two days.

I used to stress about minor mouth sores too, especially when my PCOS made me overthink everything. Simple cheek biting is safe, but if you have a sore that doesn't heal for more than two weeks, please consult a dentist just to be absolutely sure.

Let's be clear: occasional cheek biting is harmless. However, if you have a habit of chronic, severe cheek biting (morsicatio buccarum) that keeps creating open wounds, it can lead to thick white patches. Go see a dentist if you can't stop doing it.
