Hidden Dangers in Your Mouth: A Gentle Guide to the Early Signs of Oral Cancer (And How to Protect Your Smile)

A few years ago, my dentist was doing my regular cleaning. She paused. Looked closer at the inside of my cheek. Then she asked a question that made my stomach drop: "How long has this white patch been here?"

I didn't know. I'd never noticed it. It didn't hurt. It didn't bleed. It was just... there.

1. Sores or Ulcers That Don’t Heal: A common canker sore or accidental bite usually heals within 10 to 14 days. A sore that lingers, bleeds easily, or keeps coming back in the exact same spot warrants a professional look.
2. Persistent White or Red Patches:
