3. A Lump or Thickening
Any new lump, bump, or thickening in your cheek, lip, tongue, or neck that persists should be checked. It might not hurt—that doesn’t mean it’s harmless.
4. Difficulty Swallowing or Chewing
If you feel like food is getting stuck, or if swallowing becomes painful or difficult, don’t assume it’s just a sore throat.
5. Persistent Sore Throat or Hoarseness
A sore throat that lingers for weeks, or a change in your voice that doesn’t improve, can be a sign of cancer in the throat or voice box.
6. Numbness in the Mouth or Lips
Unexplained numbness or loss of feeling in any part of your mouth, lips, or tongue can indicate nerve involvement.
7. Ear Pain on One Side
Persistent ear pain without hearing loss can sometimes be referred pain from a tumor in the mouth or throat.
8. A Change in How Your Teeth Fit Together
If your dentures suddenly don’t fit, or if you notice changes in your bite, it could indicate swelling or a mass in your jaw.
9. Loose Teeth with No Obvious Cause
