Is Thumb Sucking Harmful?

Thumb sucking at an early age offers the benefit of comfort to a baby, but prolonged thumb sucking can have detrimental effects on your child's teeth and jaw, according to family dentist Dr. Frank Fruce, owner of Advanced Dental Arts in Fulton, NY. “Thumb sucking can cause skeletal changes and tooth malposition during development,” he says. He adds that if your child is finding it stressful to give up sucking his thumb, your dentist can help with a fixed oral appliance that can be used to assist with the transition.
