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!

EncourageYourChildtoStopThumbSuckingbyAge4

There's something universal about thumb sucking: nearly all babies do it, and nearly all parents worry about it. While most such worries are unfounded, you should be concerned if your child sucks their thumb past age of 4 — late thumb sucking could skew bite development.

Young children suck their thumb because of the way they swallow. Babies move their tongues forward into the space between the two jaws, allowing them to form a seal around a nipple as they breast or bottle feed. Around age 4, this “infantile swallowing pattern” changes to an adult pattern where the tip of the tongue contacts the front roof of the mouth just behind the front teeth. At the same time their future bite is beginning to take shape.

In a normal bite the front teeth slightly overlap the bottom and leave no gap between the jaws when closed.  But if thumb sucking continues well into school age, the constant pushing of the tongue through the opening in the jaws could alter the front teeth's position as they erupt. As a result they may not fully erupt or erupt too far forward. This could create an open bite, with a gap between the upper and lower teeth when the jaws are closed.

Of course, the best way to avoid this outcome is to encourage your child to stop thumb sucking before they turn four. If, however, they're already developing a poor bite (malocclusion), all is not lost — it can be treated.

It's important, though, not to wait: if you suspect a problem you should see an orthodontist for a full evaluation and accurate diagnosis. There are even some measures that could discourage thumb sucking and lessen the need for braces later. These include a tongue crib, a metal appliance placed behind the upper and lower incisors, or exercises to train the tongue and facial muscles to adopt an adult swallowing pattern. Often, a reward system for not sucking their thumbs helps achieve success as well.

Thumb-sucking shouldn't be a concern if you help your child stop before age 4 and keep an eye on their bite development. Doing those things will help ensure they'll have both healthy and straight teeth.

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.
