What Does a White Tongue Mean?
A white-coated tongue usually occurs when the tiny nodules on your tongue, called papillae, become inflamed or overgrown. This traps bacteria, dead cells, and debris, causing the tongue to appear white.
According to the Mayo Clinic, the most common causes include:
- Dehydration
- Poor oral hygiene
- Mouth breathing
- Smoking or tobacco use
- Fungal or bacterial infections
- Certain medical conditions (such as diabetes, autoimmune diseases, and digestive disorders)
👉 Key Stat:
Up to 25% of adults experience noticeable tongue discoloration during some point in their lives (American Dental Association, 2023).
