Seeing your dentist to smooth down sharp teeth.Treatment: If you're chronically getting white spots due to trauma, the solution is to prevent the injuries to the tongue in the first place. Typically, these spots won't hurt, but if the trauma is more intense and acute, like if you bit down hard on your tongue, an ulcer may form, which can be very painful, says Nor. If you have teeth with particularly sharp edges, or if you have a habit of chewing the sides of your tongue, this can cause the tissue to grow a thicker protective layer, sort of like a callus on your foot, says Felipe Nor, DDS, PhD, clinical assistant professor of oral medicine at the University of Michigan School of Dentistry. You may not even know you have a habit of chewing on your tongue - some people do it at night, when they are asleep.
