X-rays are so interwoven into dental care that we often don't think twice about them. Even so, we shouldn't take this invisible form of radiation lightly—regular exposure at high levels can affect the human body, especially in children.
The ability of x-rays to pass through tissue greatly improves our ability to diagnose tooth decay and other dental diseases. But x-rays can also potentially harm those same tissues. Because children are more sensitive to x-ray energy, they run a greater risk for cellular damage that could lead to cancer later in life.
In reality, though, these potential risks from x-rays are extremely low—so low, in fact, dental professionals regard their use as altogether safe for children. Here's why.
The ALARA principle. Dentists and other healthcare providers perform x-ray diagnostics based on a principle known as ALARA (“As low as reasonably achievable”). This means dentists only utilize x-rays to gain the most diagnostic benefit at the lowest amounts of radiation exposure. As such, ALARA guides both the development of x-ray equipment and the protocols involved in using them.
Equipment advances. Today's x-ray devices are safer and more efficient, restricting x-ray emissions to a single beam without scattering radiation into the environment. A child's radiation exposure is further lowered with the use of digital x-rays, which produce images in less time than conventional film. Because of these and other advances, children are exposed to less radiation during x-rays than what they typically receive in a day from the outside environment.
Safe practices. Following the ALARA principle, dentists are quite conservative in their use of x-rays in children. The most common means of x-ray is the bitewing, which captures images primarily of the back teeth that are more prone to decay. Bitewings, which require a lower x-ray dosage than a full mouth x-ray, are usually spaced at least six months apart or longer depending on a child's risk for dental disease.
The efficiency of modern radiographic equipment coupled with their judicious use has drastically reduced the amount of x-ray radiation to which a child may be exposed, thus lowering their risk of future health issues. The benefit for saving a child's teeth from disease is well worth their use.

Ashley Graham has a beautiful and valuable smile—an important asset to her bustling career as a plus-size model and television host. But she recently revealed on Instagram a “confrontation” between one of her teeth and a frozen oatmeal cookie. The cookie won.
Holding her hand over her mouth during the video until the last moment, Graham explained how she sneaked a cookie from her mom's freezer and took a bite of the frozen treat. Taking her hand from her mouth, she revealed her broken tooth.
Okay, maybe it wasn't an actual tooth that was broken: the denticle in question appeared to have been previously altered to accommodate a porcelain veneer or crown. But whatever was once there wasn't there anymore.
Although her smile was restored without too much fuss, Graham's experience is still a cautionary tale for anyone with dental work (and kudos to her for being a good sport and sharing it). Although dental work in general is quite durable, it is not immune to damage. Biting down on something hard, even as delicious as one of mom's frozen oatmeal cookies, could run you the risk of popping off a veneer or loosening a crown.
To paraphrase an old saying: Take care of your dental work, and it will take care of you. Don't use your teeth in ways that put your dental work at risk, tempting as it may be given your mouth's mechanical capabilities.
Even so, it's unwise—both for dental work and for natural teeth—to use your teeth and jaws for tasks like cracking nuts or prying open containers. You should also avoid biting into foods or substances with hard textures like ice or a rock-hard cookie from the freezer, especially if you have veneers or other cosmetic improvements.
It's equally important to clean your mouth daily, and undergo professional cleanings at least twice a year. That might not seem so important at first since disease-causing organisms won't infect your dental work's nonliving materials. But infection can wreak havoc on natural tissues like gums, remaining teeth or underlying bone that together often support dental enhancements. Losing that support could lead to losing your dental work.
And it's always a good idea to have dental work, particularly dentures, checked regularly. Conditions in the mouth can change, sometimes without you noticing them, so periodic examinations by a trained dental provider could prevent or treat a problem before it adversely affects your dental work.
We're glad Ashley Graham's trademark smile wasn't permanently harmed by that frozen cookie, and yours probably wouldn't be either in a similar situation. But don't take any chances, and follow these common sense tips for protecting your dental work.

The big day finally arrives when your braces come off. And there it is—your new, beautiful, straight smile! But on closer inspection you notice something else: tiny white spots on your teeth.
Those pale, chalky spots are called white spot lesions (WSLs). They occur when acid has contacted the tooth enamel for too long, dissolving essential minerals like calcium in those particular areas. The occurrences of WSLs during and after braces highlights a major challenge during orthodontic treatment—keeping your teeth clean.
Braces' wires and brackets tend to get in the way of brushing and flossing, making it easier to miss plaque—the bacterial film that produces acid—on tooth areas around the hardware. Those missed areas could in time lead to WSLs.
The main objective with WSLs is prevent them from occurring during braces wear as much as possible. To do this, you'll need to increase your time and effort brushing and flossing, especially around orthodontic hardware. You can make it easier, though, by using a few tools that often work better than regular toothbrushes and floss like interproximal toothbrushes, power brushes, floss threaders or water flossers.
You can also help lower your mouth's acidity by avoiding or limiting acidic foods and beverages, including juices, sodas, sports and energy drinks. And, by all means, keep up your regular dental cleaning schedule with your general dentist.
Should WSLs develop while you're wearing braces, don't panic. It's possible they'll diminish on their own, or at least not worsen. We can also foster re-mineralization of the enamel with applied fluoride, short bursts of laser light or a procedure called microabrasion that restores damaged areas below the enamel surface.
For more resistant WSLs, we can also inject a liquid tooth-colored resin into them that when hardened by a curing light can make those areas look translucent like normal enamel. We can also use other cosmetic solutions like bonding or veneers to improve your teeth's appearance.
Like other dental problems, dealing with a WSL is usually more successful if caught and treated early. So, check your teeth often while wearing braces, and if you notice anything unusual don't hesitate to call your dentist.
