Thumb Sucking – Breaking the Habit Early

Many children suck their thumbs or fingers because the habit makes them feel safe and secure. Many children who suck their thumbs quit the habit on their own between the ages of 2 and 4 years.

However, if the child continues to suck on the thumb after three years of age, problems with their biting can arise. You can look for thumb sucking prevention devices online at

For example, some children who suck their thumb develop what is known as an open bite. This is a condition where there is an open space between the upper and lower teeth when the child bites.

Not only can this habit of thumb sucking cause problems with the alignment of your teeth, it can also cause unwanted changes to your jaw.

What to do if your child persists thumb sucking

Use positive reinforcement

If your child doesn't suck his thumb, offer a compliment or even a small snack to add a tale of when they go to bed or go to the park.

Identify all possible triggers

If your child sucks his thumb in response to stress or boredom, determine where the problem lies. If stress is the trigger, comfort your child with an extra hug.

Remind your child

Many children suck their thumbs without thinking about the habit. Instead of arguing, criticizing, or making fun of your child when you see them sucking their thumb, carefully remind your child to suck their thumbs so they can stop without feeling embarrassed.
