Don’t ignore your discoloured tongue. Tongue discolouration can be a sign of deeper issues like diabetes and oral cancer. Here are the causes of tongue discolouration.

Causes of discolouration:

– Fever and dehydration.

– Oral thrush, a condition that also causes white patches, burning and bad taste.

– Tobacco use, poor oral hygiene, malnutrition

– Leukoplakia and medication.

See your dentist for an examination and cleaning of your teeth and tongue. Always rinse your mouth after consuming staining foods like wine and grapes.
