A white-coated tongue is the body’s quiet alarm bell, often dismissed until it refuses to go away.
In many cases, it’s a buildup of dead cells, bacteria, and food particles trapped between
inflamed papillae—usually from rushed brushing and skipping the tongue entirely.
Dehydration makes things worse, starving the mouth of saliva, its natural cleansing system,
and allowing a stubborn white film to spread, especially at the back of the tongue.
