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. Â 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.

A recent episode of “America’s Got Talent” featured an engaging 93-year-old strongman called The Mighty Atom Jr. The mature muscleman’s stunt: moving a full-sized car (laden with his octogenarian “kid brother,” his brother’s wife, plus Atom’s “lady friend”) using just his teeth. Grinning for host Howie Mandel, Atom proudly told the TV audience that his teeth were all his own; then he grasped a leather strap in his mouth, and successfully pulled the car from a standstill.
We’re pleased to see that the Atom has kept his natural teeth in good shape: He must have found time for brushing and flossing in between stunts. Needless to say, his “talent” isn’t one we’d recommend trying at home. But aside from pulling vehicles, teeth can also be chipped or fractured by more mundane (yet still risky) activities — playing sports, nibbling on pencils, or biting too hard on ice. What can you do if that happens to your teeth?
Fortunately, we have a number of ways to repair cracked or chipped teeth. One of the easiest and fastest is cosmetic bonding with tooth-colored resins. Bonding can be used to fill in small chips, cracks and discolorations in the teeth. The bonding material is a high-tech mixture of plastic and glass components that’s extremely lifelike, and can last for several years. Plus, it’s a procedure that can be done right in the office, with minimal preparation or discomfort. However, it may not be suitable for larger chips, and it isn’t the longest-lasting type of restoration.
When more of the tooth structure is missing, a crown (or cap) might be needed to restore the tooth’s appearance and function. This involves creating a replacement for the entire visible part of the tooth in a dental lab — or in some cases, right in the office. It typically involves making a model of the damaged tooth and its neighbors, then fabricating a replica, which will fit perfectly into the bite. Finally, the replacement crown is permanently cemented to the damaged tooth. A crown replacement can last for many years if the tooth’s roots are in good shape. But what if the roots have been dislodged?
In some cases it’s possible to re-implant a tooth that has been knocked out — especially if it has been carefully preserved, and receives immediate professional attention. But if a tooth can’t be saved (due to a deeply fractured root, for example) a dental implant offers today’s best option for tooth replacement. This procedure has a success rate of over 95 percent, and gives you a natural looking replacement tooth that can last for the rest of your life.
So what have we learned? If you take care of your teeth, like strongman Atom, they can last a long time — but if you need to move your car, go get the keys.
