White spots on the inner cheeks are commonly due to frictional keratosis (cheek biting), mild irritation after dental treatment, or normal anatomical variations like Fordyce spots. These are usually harmless, painless, and seen in many adults. Maintain good oral hygiene and avoid cheek biting. If the spots change in size, color, or persist beyond a few weeks, a dental examination is advised for confirmation.
