Thumb Sucking and Pacifier Habits: When to Worry and How to Help

Sucking on a thumb, finger or pacifier is a natural way for babies and toddlers to feel secure. For most children it is nothing to worry about, but habits that last too long can affect the teeth and jaws.

Is digit sucking normal?

Yes. Many babies suck their thumbs before they are even born, and most children give up the habit on their own between ages two and four.

When it can become a problem

Concern grows if the habit continues once permanent teeth begin to come in, usually around age six. Prolonged or forceful sucking can push the front teeth forward, create an open bite, narrow the upper jaw or change how the teeth fit together.

How to help your child stop

• Praise and reward your child on the days they don't suck, rather than scolding or punishing.

• Notice when it happens, such as when your child is tired, bored or anxious, and offer comfort or a distraction.

• Involve your child so that stopping feels like their own goal.

• Ask your pediatric dentist for help. We can explain the habit's effects to your child in a friendly way and discuss other options if needed.

What about pacifiers?

Pacifier habits follow similar guidance. Weaning is generally easier earlier than later, and many dentists recommend stopping by around age three.
