For many children, thumb sucking is a source of comfort. This is normal and nothing to worry about, as long as they stop by about age 4. However, if your child continues sucking their thumb and you need help helping them break the habit, our dentists in Tuscumbia, Alabama, are here to help! We encourage you to contact SRD on 5th at 256-712-4005 today for more information and to schedule a visit with our SRD on 5th team.
