Tongue Injury

By David F. Murchison, DDS, MMS, Clinical Professor, Department of Biological Sciences; Clinical Professor, The University of Texas at Dallas; Texas A & M University Baylor College of Dentistry

Traumatic injury is the most common cause of tongue discomfort. The tongue has many nerve endings for pain and touch and is more sensitive than most other parts of the body. The tongue is frequently bitten accidentally but heals quickly. A sharp, broken filling or tooth can do considerable damage to this delicate tissue. Shallow sores (ulcers) heal fairly quickly, and those caused by trauma usually do not persist more than 3 weeks.
