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!

You may not always be able to tell if your child's bite isn't developing properly. Â That's why you should have them undergo an orthodontic evaluation around age 6 to uncover any emerging problems with tooth misalignment.
Still, there are some visible signs all's not well with their bite. As the primary (baby) teeth give way, the permanent teeth erupt sequentially around ages 6 to 8. As they come in, you should notice that each tooth fits uniformly next to each other without excessive gaps or, on the other end of the spectrum, not crowded together in crooked fashion. Upper teeth should also fit slightly over the lower teeth when the jaws are shut.
If their teeth appearance deviates from these norms, they may have a bite problem. Here are 4 abnormalities you should watch for.
Underbite or deep bite. As we mentioned, the front teeth should cover the lower teeth with the jaws shut. In an underbite, the reverse happens — the lower teeth are in front of the upper teeth. It's also a problem if the upper teeth cover the lower teeth too much (often referred to as “deeply”).
Open bite. This occurs when there's a gap between the upper and lower front teeth while the jaws are shut together. One possible cause is late thumb sucking, which can put undue pressure on the front teeth and cause them to develop too far forward while forcing the bottom front teeth further backwards.
Crossbites. This kind of bite occurs when some of the teeth don't fit properly over their counterparts, while others do. Crossbites can occur anywhere in the mouth, for example the upper front teeth fitting behind the lower front teeth while the back teeth overlap normally, or the reverse (front normal, back abnormal).
Misalignments and Abnormal Eruptions. Sometimes upper teeth may align too far forward, a situation known as protrusion. Conversely, lower teeth (or the jaw itself) may come in too far back (retrusion). Because a primary tooth might be out of position or not lost in the proper sequence, a permanent tooth might noticeably erupt out of its proper position.
If you notice any of these situations with your child's teeth see your dentist or orthodontist soon for a full examination. If caught early, we may be able to take action that will lessen or even eliminate the problem.
