Some children persist in sucking their thumbs or fingers beyond their preschool years. For these children, the activity continues to be a source of comfort, relaxation, and security. It may even help them fall asleep at night. However, it's essential to be aware that in the long-term, a finger sucking habit is not healthy.
If your child's thumb or finger sucking habit is still present when the permanent teeth begin to come in, your child is at a higher risk of developing a bad bite. By the age of five or six years, you need to constructively and gently help your child stop the habit.
It's also a good idea to have a comprehensive evaluation at this time. Your pedodontist can assess if there are any habit related alterations to the alignment of your child's teeth or jaws, or if it is affecting their speech or swallowing patterns. They can also discuss habit control strategies with you, as well as follow your child's bite and facial development as they grow. If interceptive appliances or corrective orthodontic care are recommended, the timetable and best options in care will be explained in complete detail.
