If your tongue is white, this is a clear sign that you may be suffering from a variety of health conditions, some mild and others potentially more serious. A white tongue can occur for several reasons, ranging from poor oral hygiene to an underlying health condition. Understanding the causes and seeking appropriate treatment can help resolve the issue and prevent complications.

1. Poor Oral Hygiene: The most common cause of a white tongue is poor oral hygiene. When you fail to brush your tongue or clean your mouth properly, bacteria, dead cells, and food particles can accumulate on the surface of the tongue. This buildup leads to a white coating, especially on the back of the tongue. Regular brushing and flossing, along with using a tongue scraper, can help prevent this condition.
