Spots on the tongue

Spots on the tongue can be caused by a variety of conditions. They can range from small, white spots to large, red patches. They may be raised or flat, and can have a rough or smooth texture. Spots may develop suddenly or gradually over time. Some are temporary and may resolve on their own, while others may require medical attention. Common causes of spots on the tongue include bacterial or fungal infections, irritation from certain foods, and vitamin deficiencies.
