Best dental clinic near me | 🦷 Can Sharp or Broken Teeth Cause Oral Cancer? Understanding the Connection Sharp or broken teeth can repeatedly irritate the tongue, cheeks, or gums, causing recurring ulcers, sores, or discomfort. Although there is no proven direct link between sharp teeth and oral cancer, persistent irritation or a non-healing oral lesion should not be ignored. A mouth ulcer, lump, red or white patch, or sore that does not heal within two weeks requires professional evaluation. If you are searching for oral cancer screening in Chennai or a dentist for a non-healing mouth ulcer near me, early consultation is important. At Dr. Akkshaya Dental & Aesthetics in Adambakkam, Chennai, we provide comprehensive oral examinations to identify unusual changes and guide you toward appropriate care.
