Plaque on the tongue

Plaque on the tongue is a common symptom of oral health issues. It appears as a white, yellow, or gray film on the tongue, which can vary in thickness. Plaque can develop due to poor oral hygiene, dry mouth, or the use of certain medications. It can also be caused by certain medical conditions, such as diabetes or HIV. Plaque can manifest as a burning sensation, bad taste, or difficulty swallowing. If left untreated, plaque can lead to more serious issues such as periodontal disease.
