Kicking the thumb-sucking habit is challenging but not impossible. The good news is any emerging dental problems created by thumb-sucking are reversible at their age.

As you may already know, thumb-sucking leads to dental problems. Your child is putting pressure on the roof of their mouth, upper jaw, and permanent teeth coming in. This may lead to mouth narrowing, crooked teeth, speech impediment, or protruding teeth (‘buck teeth’).

Peer pressure at school might encourage them to stop. At home, stay calm and patient. Praise them when they don't suck their thumb. Point it out when they do. Set activities for them to do that keep them busy. Ask them how they're feeling. Teach them how to cope with disappointment. Get them to dance, listen to music, or draw when they're feeling blue.

Thumb-sucking could be a coping mechanism for emotional distress. Use reinforcements such as treats or prizes when they don’t suck their thumb. If these methods don’t work, talk to your dentist. They may be able to help. Each child needs something different. A little outside support might go a long way.
