ThumbSuckingandTongueThrustingCouldCauseaPoorBite

There are many things to be concerned about with your infant. Thumb sucking shouldn't be one of them—at least not yet. Practically universal among young children, the habit normally fades by age four with no real harm.

If it persists beyond that age, however, it can lead to a poor bite (malocclusion). Late thumb sucking may also have a connection with another problem—the inability of a child to transition from an infantile swallowing pattern to an adult pattern.

A baby while swallowing thrusts their tongue forward to help create a seal around a breast or bottle nipple during nursing. This normally changes about age 4, though, to a positioning of the tongue against the roof of the mouth when swallowing. But if they don't transition and continue to thrust the tongue forward, it can place undue pressure on the front teeth and cause them to develop too far forward.

The result may be an open bite, in which a gap exists between the upper and lower teeth even when the jaws are shut. An open bite can also happen with late thumb sucking, but instead of the tongue, their thumb presses against the teeth.

As to thumb-sucking, parents should encourage their child to stop the habit beginning around age 3, if they haven't already begun to do so. The best approach is to use some form of positive reinforcement such as praise or treats. The sooner the habit ceases after age 4, the lower their risk for developing an open bite.

You may also need to be alert to continued tongue thrusting while swallowing, which may still continue even after they no longer suck their thumb. In that case, your child may need orofacial myofunctional therapy (OMT), a series of exercises directed by a trained therapist to retrain the muscles involved with swallowing. This therapy could further help a child properly transition to an adult swallowing pattern.

Open bites can be corrected orthodontically later in life. But by being alert to your child's oral habits, as well as the way they're swallowing, you and your dentist may be able to intervene and eliminate or at least lessen the development of this type of problem bite.

EncourageYourChildtoStopThumbSuckingAroundAge3

One of the biggest concerns we hear from parents is about their child's thumb sucking habit. Our advice: if they're under age 4, there's no need for concern — yet. If they're older, though, you should be concerned about the possible effect on their bite.

Thumb sucking is a universal habit among infants and toddlers and is related to their swallowing pattern during feeding. As they swallow, their tongue thrusts forward to create a seal with the lips around the breast or a bottle nipple. Many pediatricians believe thumb sucking replicates nursing and so has a comforting effect on infants.

Around age 4, though, this swallowing pattern begins to change to accommodate solid food. The tongue now begins to rest at the back of the top front teeth during swallowing (try swallowing now and you'll see). For most children, their thumb sucking habit also fades during this time and eventually stops.

But for whatever reason, some children don't stop. As the habit persists, the tongue continues to thrust forward rather than toward the back of the top front teeth. Over time this can place undue pressure on both upper and lower front teeth and contribute to the development of an open bite, a slight gap between the upper and lower teeth when the jaws are shut.

While late childhood thumb sucking isn't the only cause for an open bite (abnormal bone growth in one jaw is another), the habit is still a prominent factor. That's why it's important that you start encouraging your child to stop thumb sucking around age 3 and no later than 4. This is best accomplished with positive reinforcement like rewards or praise.

If they've continued the habit a few years after they should have stopped, we may also need to check to see if their swallowing mechanism has become stunted. If so, we may need to use certain exercises to retrain their tongue to take the proper position during swallowing.

While you shouldn't panic, it's important to take action to stop thumb sucking before it becomes a long-term problem. A positive, proactive approach will help avoid costly orthodontic problems later in their lives.
