Sucking is a natural reflex and infants and young children may use thumbs, fingers, pacifiers and other objects on which to suck. It may make them feel secure and happy or provide a sense of security at difficult periods. Since thumb sucking is relaxing, it may induce sleep.

How is thumb sucking and pacifiers harmful for a child’s teeth?

Generally, thumb sucking and pacifier habits will only become a problem if they go on for a very long period of time. Many children stop these habits on their own, but if they are still sucking their thumbs or fingers when the permanent teeth arrive, a mouth appliance may be recommended by your pediatric dentist to prevent further issues.
