Have you ever noticed your tongue looking whitish, coated, or patchy? While many people think it’s harmless or just caused by poor oral hygiene, a white tongue can actually be a warning sign of underlying health issues. It’s your body’s way of signaling that something may not be working properly—either in your mouth or elsewhere in your body.
Understanding the possible causes and taking early action can help prevent more serious health problems and maintain overall wellness.
