Thumb sucking is a natural self-soothing reflex for infants that usually stops on its own between ages 2 and 4. However, if the habit persists after the permanent teeth erupt, it can cause dental misalignment, speech issues, or jaw problems. For persistent habits, some professionals may recommend bandaging the thumb, wearing specialized hand coverings at night, or using dental appliances.
