Thumb Sucking

Thumb sucking is a natural reflex in babies and young children. Most children lose interest in thumb sucking and dummies at two to four years of age.

Children who continue to suck their thumb or fingers after their permanent teeth have appeared risk developing crooked teeth, particularly if the sucking is forceful or frequent. Also, speech defects may arise, especially with ‘s’ and ‘th’ sounds.

Gently encourage your child to give up thumb sucking. See your dentist for advice if your child cannot stop thumb sucking by the end of their first year at school. In rare cases, referral to a child psychologist may be helpful.
