What are some common tongue problems?

Common tongue problems include black, hairy tongue, burning tongue or glossodynia, and traumatic injuries to the tongue, says MedlinePlus. Children biting their tongue accidentally is a fairly common injury, says Seattle Children's Hospital. Most of these injuries heal by themselves.

Black, hairy tongue is a benign condition where dead cells accumulate on the tongue, says Mayo Clinic. They are stained a dark color from food, coffee, tobacco, yeast or bacteria. This condition often resolves on its own without medical treatment.

As its name implies, burning tongue disease presents as a feeling that the patient's tongue is burning or has been scalded, says Mayo Clinic. The mouth may also be dry and the sense of taste altered.
