What should I do about a white coating on my tongue?

White tongue coating may be caused by various factors, and the following measures can help alleviate it: 1. Maintain oral hygiene: Brush teeth twice daily, use dental floss or floss picks to clean between teeth, and use mouthwash to rinse the mouth. These practices help remove bacteria and debris in the oral cavity and reduce the formation of tongue coating. 2. Tongue cleaning: Gently scrape the tongue coating using a tongue scraper or the back of a toothbrush, moving from the base of the tongue forward. This helps remove bacteria and debris from the tongue surface and maintain tongue cleanliness. 3. Dietary adjustment: Pay attention to dietary choices and avoid excessive consumption of unhealthy foods such as greasy, spicy, or high-sugar items. Increase intake of fresh fruits and vegetables to support digestive system health. 4. Seek medical advice: If the white tongue coating persists or is accompanied by other uncomfortable symptoms, it is recommended to seek timely medical consultation for diagnosis and treatment by a professional healthcare provider.
