A white coating on the tongue can have several possible causes.
In many cases, debris, bacteria, and dead cells accumulate between the small projections on the tongue’s surface. Dry mouth, dehydration, smoking, and oral hygiene habits can contribute.
Gently cleaning your tongue with a toothbrush or tongue scraper may help reduce this type of coating.
However, not every white area is simply buildup. Persistent patches, soreness, burning, or changes that do not improve should be examined by a dental or medical professional.
Avoid aggressively scraping or attempting to remove areas that are painful or firmly attached.
Your dentist can examine your tongue and other oral tissues as part of a comprehensive dental assessment.
If you notice a persistent change in the colour, texture, or appearance of your tongue, mention it at your next appointment.
Port Moody Smile Dental provides comprehensive oral examinations that look beyond just the teeth and include the surrounding tissues of the mouth.
