A white tongue is often your body’s way of signaling that something in your oral or overall health needs care.
Common Causes of a White Tongue
1. Poor Oral Hygiene
Not brushing your tongue allows bacteria and food particles to build up, forming a visible white film.
Tip: Brush your tongue gently every day or use a tongue scraper to remove the coating.
2. Dehydration or Dry Mouth
A dry mouth decreases saliva, which normally cleanses the tongue. Less saliva means bacteria and debris collect more easily.
Tip: Drink plenty of water and chew sugar-free gum to stimulate saliva production.
3. Oral Thrush (Yeast Infection)
Oral thrush is caused by an overgrowth of Candida yeast. It can create a thick white coating that may be accompanied by:
-
Soreness or burning sensation
