There are many children that find thumb-sucking to be a very comforting act. It is estimated that about 75% to 95% of infants suck their thumbs, so you are not alone if your child starts sucking his or her thumb. In the majority of cases, you do not have anything to worry about if your child is sucking his or her thumb. When your child is sucking his or her thumb, you should watch the behavior to see if the thumb-sucking as the potential to affect your child’s oral health.

What Is Normal Thumb-Sucking Behavior?

Many children start sucking their thumb at a very young age and some even start sucking their thumb inside the womb. Sucking their thumb can provide a sense of security and contentment for a children. Some children find thumb sucking to be relaxing and suck their thumb when they fall asleep.

The majority of children will stop sucking their thumb on their own between the ages of two and four. The American Dental Association has released a study showing that most children stop sucking their thumb when the habit is no longer useful to them. If your child is still sucking his or her thumb when their permanent teeth start to erupt, you may want to take action to break the habit.

What Signs Should I Watch For?

First, you should watch how your child is sucking his or her thumb. If your child is sucking passively, with his or her thumb resting gently in the mouth, it is less likely that the habit will cause problems. If your child is an aggressive thumb-sucker and he or she is placing pressure on the mouth of teeth when sucking, the habit may cause dental problems. Continuing this habit for an extended amount of time can cause problems with the way that the teeth grow in and even with the shape of your child’s face.
