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.

ThumbSuckingOneofManyFactorstoConsiderWhenTreatingaPoorBite

It’s true — thumb sucking beyond age 4 can cause bite problems for permanent teeth. But prolonged thumb sucking is just one of a number of possible contributing factors for a bad bite (malocclusion). A dentist must identify all the factors involved when a bad bite is present — their involvement is essential for a successful treatment outcome.

A fairly benign habit for infants and toddlers, thumb sucking is related to an “infantile swallowing pattern” young children use by thrusting their tongues forward between the upper and lower teeth when they swallow. Around age 4, though, they usually transition to an adult swallowing pattern in which the tongue rests on the roof of the mouth just behind the front teeth. Thumb sucking stops for most children around the same time.

Thumb sucking beyond this age, though, can put increased pressure on incoming permanent teeth pushing them forward. This could lead to an “open bite” in which the upper and lower teeth don’t meet when the jaws are closed. The tongue may also continue to thrust forward when swallowing to seal the resulting gap, which further reinforces the open bite.

Before treating the bite with braces, we must first address the thumb sucking and improper tongue placement when swallowing — if either isn’t corrected the teeth could gradually revert to their previous positions after the braces come off. Besides behavioral incentives, we can also employ a thin metal appliance called a “tongue crib” placed behind the upper and lower incisors. A tongue crib discourages thumb sucking and makes it more difficult for the tongue to rest within the open bite gap when swallowing, which helps retrain it to a more normal position.

An open bite can also occur if the jaws develop with too much vertical growth. Like thumb sucking and improper tongue placement, abnormal jaw growth could ultimately cause orthodontic treatment to fail. In this case, though, surgery may be necessary to correct the jaw structure.

With all these possible variables, our first step needs to be a thorough orthodontic exam that identifies all the cause factors for your child’s specific malocclusion. Knowing if and how thumb sucking may have contributed to the poor bite will help us design a treatment strategy that’s successful.

MonitoringYourChildsThumbSuckingCouldHelpAvoidFutureBiteProblems

Although distressing to many parents, infants and toddlers sucking their thumb is a common if not universal habit. Most children phase out of it by around age 4, usually with no ill effects. But thumb-sucking continuing into late childhood could prove problematic for a child’s bite.

Thumb sucking is related to how young children swallow. All babies are born with what is called an infantile swallowing pattern, in which they thrust their tongues forward while swallowing to ensure their lips seal around a breast or bottle nipple when they nurse. Thumb-sucking mimics this action, which most experts believe serves as a source of comfort when they’re not nursing.

Around 3 or 4, their swallowing transitions to a permanent adult swallowing pattern: the tip of the tongue now positions itself against the back of the top front teeth (you can notice it yourself when you swallow). This is also when thumb sucking normally fades.

If a child, however, has problems transitioning to an adult pattern, they may continue to thrust their tongue forward and/or prolong their thumb-sucking habit. Either can put undue pressure on the front teeth causing them to move and develop too far forward. This can create what’s known as an open bite: a slight gap still remains between the upper and lower teeth when the jaws are shut rather than the normal overlapping of the upper teeth over the lower.

While we can orthodontically treat an open bite, we can minimize the extent of any treatments if we detect the problem early and intervene with therapies to correct an abnormal swallowing pattern or prolonged thumb sucking. For the former we can assist a child in performing certain exercises that help retrain oral and facial muscles to encourage a proper swallowing pattern. This may also help diminish thumb sucking, but we may in addition need to use positive reinforcement techniques to further discourage the habit.

To stay ahead of possible problems with thumb sucking or the swallowing pattern you should begin regularly taking them to the dentist around their first birthday. It’s also a good idea to have an orthodontic evaluation around age 6 for any emerging bite problems. Taking these positive steps could help you avoid undue concern over this common habit.

DontPanicTakeMethodicalApproachtoHelpYourChildStopThumbSucking

One of the most frequent concerns parents express to us is their child’s thumb or finger sucking habit. The good news, though, is that thumb sucking is a completely normal activity for babies and young children, and if they stop by age 4 it should have no adverse effects on their future bite.

In fact, there are positive aspects to thumb sucking: it provides babies with a sense of security, as well as a way to learn about the world. As a child grows and becomes more confident with their surroundings, the thumb sucking habit will fade and eventually stop: for most children this occurs between the ages of two and four.

If, however, the habit continues later in childhood, there is a chance the upper front teeth may be influenced to tip toward the lip during eruption and come into an improper position that could also adversely affect jaw development. The same concern exists for pacifier use — we recommend weaning a child off a pacifier by the time they’re eighteen months of age.

If your child still has a thumb or finger sucking habit as they prepare to enter school, it’s quite appropriate to work on getting them to stop. Punishment, shaming or similar negative approaches, however, aren’t the best ways to accomplish this: it’s much more effective to try to modify their behavior through reward, praise or some creative activity.

Another factor that may help is to begin regular dental visits around their first birthday. Regular checkups give us a chance to monitor the development of their bite, especially if thumb sucking continues longer than normal. We can also assist you with strategies to encourage them to stop thumb sucking or pacifier use.

Thumb sucking that continues later than normal isn’t a cause for panic, but it does require attention and action. Helping your child “grow” past this stage in their life will improve their chances of developing a normal and healthy bite.

TakePositiveActionwithYourChildsThumb-SuckingHabit

As a parent you’re concerned with a number of issues involving your child’s health, not the least of which involves their teeth. One of the most common is thumb-sucking.

While later thumb-sucking is a cause for concern, it’s quite normal and not viewed as harmful in infant’s and very young children. This universal habit is rooted in an infant swallowing pattern: all babies tend to push the tongue forward against the back of the teeth when they swallow, which allows them to form a seal while breast or bottle feeding. Infants and young children take comfort or experience a sense of security from sucking their thumb, which simulates infant feeding.

Soon after their primary teeth begin to erupt, the swallowing pattern changes and they begin to rest the tongue on the roof of the mouth just behind the front teeth when swallowing. For most children thumb sucking begins to fade as their swallowing pattern changes.

Some children, though, continue the habit longer even as their permanent teeth are beginning to come in. As they suck their thumb the tongue constantly rests between the front teeth, which over time may interfere with how they develop. This can cause an “open bite” in which the upper and lower teeth don’t meet properly, a problem that usually requires orthodontic treatment to correct it.

For this reason, dentists typically recommend encouraging children to stop thumb-sucking by age 3 (18-24 months to stop using a pacifier). The best approach is positive reinforcement — giving appropriate rewards over time for appropriate behavior: for example, praising them as a “big” boy or girl when they have gone a certain length of time without sucking their thumb or a pacifier. You should also use training or “Sippy” cups to help them transition from a bottle to a regular cup, which will further diminish the infant swallowing pattern and need for thumb-sucking.

Habits like thumb-sucking in young children should be kept in perspective: the habit really isn’t a problem unless it goes on too long. Gentle persuasion, along with other techniques we can help you with, is the best way to help your child eventually stop.
