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.

ActressEmmaStoneRevealsHowThumbSuckingAffectedHerTeeth

It's no secret that many of Hollywood's brightest stars didn't start out with perfectly aligned, pearly-white teeth. And these days, plenty of celebs are willing to share their stories, showing how dentists help those megawatt smiles shine. In a recent interview with W magazine, Emma Stone, the stunning 28-year-old star of critically-acclaimed films like La La Land and Birdman, explained how orthodontic appliances helped her overcome problems caused by a harmful habit: persistent thumb sucking in childhood.

“I sucked my thumb until I was 11 years old,” she admitted, mischievously adding “It's still so soothing to do it.” Although it may have been comforting, the habit spelled trouble for her bite. “The roof of my mouth is so high-pitched that I had this huge overbite,” she said. “I got this gate when I was in second grade… I had braces, and then they put a gate.”

While her technical terminology isn't quite accurate, Stone is referring to a type of appliance worn in the mouth which dentists call a “tongue crib” or “thumb/finger appliance.” The purpose of these devices is to stop children from engaging in “parafunctional habits” — that is, behaviors like thumb sucking or tongue thrusting, which are unrelated to the normal function of the mouth and can cause serious bite problems. (Other parafunctional habits include nail biting, pencil chewing and teeth grinding.)

When kids develop the habit of regularly pushing the tongue against the front teeth (tongue thrusting) or sucking on an object placed inside the mouth (thumb sucking), the behavior can cause the front teeth to be pushed out of alignment. When the top teeth move forward, the condition is commonly referred to as an overbite. In some cases a more serious situation called an “open bite” may develop, which can be difficult to correct. Here, the top and bottom front teeth do not meet or overlap when the mouth is closed; instead, a vertical gap is left in between.

Orthodontic appliances are often recommended to stop harmful oral habits from causing further misalignment. Most appliances are designed with a block (or gate) that prevents the tongue or finger from pushing on the teeth; this is what the actress mentioned. Normally, when the appliance is worn for a period of months it can be expected to modify the child's behavior. Once the habit has been broken, other appliances like traditional braces or clear aligners can be used to bring the teeth into better alignment.

But in Stone's case, things didn't go so smoothly. “I'd take the gate down and suck my thumb underneath the mouth appliance,” she admitted, “because I was totally ignoring the rule to not suck your thumb while you're trying to straighten out your teeth.” That rule-breaking ended up costing the aspiring star lots of time: she spent a total of 7 years wearing braces.

Fortunately, things worked out for the best for Emma Stone: She now has a brilliant smile and a stellar career — plus a shiny new Golden Globe award!

KnowWhattodotoEaseYourChildOutoftheThumbSuckingHabit

Thumb or finger sucking is a normal activity for babies and young children — they begin the habit while still in the womb and may continue it well into the toddler stage. Problems with tooth development and alignment could arise, however, if the habit persists for too long.

It’s a good idea, then, to monitor your child’s sucking habits during their early development years. There are also a few things you can do to wean them off the habit before it can cause problems down the road.

  • Eliminate your child’s use of pacifiers by eighteen months of age. Studies have shown that the sucking action generated through pacifiers could adversely affect a child’s bite if they are used after the age of 2. Weaning your child off pacifiers by the time they are a year and a half old will reduce the likelihood of that occurring.
  • Encourage your child to stop thumb or finger sucking by age 3. Most children tend to stop thumb or finger sucking on their own between the ages of 2 and 4. As with pacifiers, if this habit continues into later childhood it could cause the upper front teeth to erupt out of position and tip toward the lip. The upper jaw also may not develop normally.
  • Replace your child’s baby bottle with a training cup around one year of age. Our swallowing mechanism changes as we grow; introducing your child to a training cup at around a year old will encourage them to transition from “sucking” to “sipping,” and make it easier to end the thumb or finger sucking habit.
  • Begin regular dental visits for your child by their first birthday. The Age One visit will help you establish a regular habit of long-term dental care. It’s also a great opportunity to evaluate your child’s sucking habits and receive helpful advice on reducing it in time.

While your child’s thumb or finger sucking isn’t something to panic over, it does bear watching. Following these guidelines will help your child leave the habit behind before it causes any problems.
