What causes a coated tongue? i can't get rid of it. i have tried a tongue scraper, brushing my tongue, mouth wash, gargling with salt water. no luck.

Coated Tongue: I commend you for your concern about your Health! Coated tongue can be due to: • Smoking or other oral tobacco use • Alcohol use • Mouth breathing • Low roughage diet — eating mostly soft or mashed foods • Mechanical irritation from sharp tooth edges or dental appliances • Fever • Prolonged use of antibiotics that may cause oral yeast infection See Physician for Diagnosis and Treatment.

See DDS: What are your personal habits? Do you smoke, drink coffee all day long? A tongue scraper should be an adjunct in addition to brushing and flossing on a regular basis. Speak to your dentist if this is still problematic.
