Thumb Sucking

Along with favorite blankets, teddy bears, and nap time, thumb sucking can be one of the most comforting activities of childhood. According to a recent report, between 75% and 95% of infants suck their thumb, so chances are there’s a thumb sucker (or a former thumb sucker) in your family. Is this cause for worry?

In most cases, the answer is no. However, it’s important to pay attention to your child’s habits in case his or her behavior has the potential to affect overall oral health.

What is normal thumb-sucking behavior?

Most children begin sucking their thumbs or fingers from a very young age; many even start inside the womb. Sucking is a natural reflex for an infant and it serves an important purpose.

The activity often provides a sense of security and contentment for a young one. It can also be relaxing, which is why many children suck their thumb as they fall asleep.

According to the American Dental Association, most children stop thumb sucking on their own between the ages of two and four. They simply grow out of a habit that is no longer useful to them.

However, some children continue sucking beyond the preschool years (although studies show that the older a child gets, the lower the chances are of continuing the habit). If your son or daughter is still sucking when permanent teeth start to emerge, it may be time to take action to break the habit.

What signs should I watch for?

First, take note of how your child sucks his or her thumb. If the sucking is passive, with the thumb gently resting inside the mouth, it is less likely to cause damage.

If, on the other hand, the thumb sucking is aggressive, and places pressure on the mouth or teeth, the habit may cause problems with tooth alignment and proper mouth growth. Extended sucking affects both the teeth and the shape of the face and may lead to a need for orthodontic treatment in the future.

How can I help my child quit thumb sucking?

Should you need to help your child end the habit, follow these guidelines:

1. Always be supportive and positive. Instead of punishing your child for thumb sucking, give praise when he or she doesn’t.
2. Put a band-aid on your child’s thumb or a sock over the hand at night. Let your little one know this is not a punishment, but rather a way to help remember to avoid sucking.
3. Start a progress chart and let your youngster put a sticker up every day he or she doesn’t suck. If your child makes it through a week without doing it, he or she gets to choose a prize. When the whole month is full, reward your child with something great (a toy or new video game); by then the habit should be over. Making your child an active participant in treatment will increase the willingness to break the habit.
4. If you notice your child sucking when he or she is anxious, work on alleviating the anxiety rather than focusing on the thumb sucking.
5. Take note of the times your little one tends to suck (long car rides, while watching movies), and create diversions during these occasions.
6. Explain clearly what might happen to the teeth if he or she keeps thumb sucking.

Whatever your method, always remember that your child needs your support and understanding during the process of breaking the habit of thumb sucking.
