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.

Dinnertime is a great opportunity to enjoy not only your meal, but also the company of friends and family. But a temporomandibular joint disorder (TMD) can drain the pleasure from these dining experiences if the mere act of chewing is a painful ordeal.
Besides curbing pleasure while dining, eating difficulties caused by TMD can also affect your health: You may find yourself limiting your choices to only those that cause the least amount of discomfort. But those restricted choices may deprive you of a balanced diet essential to overall well-being.
But there are ways to reduce your discomfort and enjoy a greater abundance of healthy foods, as well as your dining experience. Here are 3 tips to make eating easier if you have TMD.
Prepare your food. Easing TMD discomfort starts while you're preparing your food to cook. First off, remove the tougher peel or skin from apples, potatoes or similar fruits and vegetables. And, be sure to chop foods into small enough pieces to reduce how much your jaws must open to comfortably chew your food.
Choose “wetter” cooking methods. One of the best ways to soften foods is to moisten them, either during the cooking process or by adding it in some form to the dish. Use braising techniques when you cook as much as possible. And try to incorporate sauces or gravies, especially with leaner meats, for added moisture.
Modify your eating habits. Food prep is only one aspect of a more comfortable dining experience with TMD—you can also benefit from modifying how you eat. Concentrate on taking smaller bites of food and slow down your chewing motion. You should also limit how much you open your jaw while chewing to keep it within your comfort range as much as possible.
With a little experimentation, you can find the right balance between a wide variety of foods and more comfortable eating. If you have TMD, using these tips could help mealtime become a delightful—and more nutritious—experience.

You could have an unattractive smile because of a chipped tooth or one slightly out of alignment. Or, it could be both of the above, plus some heavy staining to boot. Correcting each flaw individually might require a combination of different methods like orthodontics or porcelain crowns, which can take an extended period of time to complete.
But you may be able to correct numerous smile flaws with just one method—and in no more than a couple of treatment visits. It's called direct veneers.
Unlike regular veneers, direct veneers don't require a dental technician to craft a thin porcelain shell to bond over teeth. Rather, a dentist applies a tooth-colored material called composite resin to the problem teeth and "sculpts" an entirely new look that can correct multiple dental flaws at one time.
The dentist usually begins the process by creating a model ("wax-up") of proposed changes based on physical impressions of the jaw and teeth. Both dentist and patient can study the model and modify it if necessary, when finalizing the treatment plan.
At a subsequent appointment, the dentist prepares the tooth surface for bonding by removing a thin layer of tooth enamel, then shapes the teeth to better accommodate the composite resin. This tooth prep is similar to that done with traditional veneers, so it's permanent—the teeth will require some form of restoration from then on.
After applying an etchant and a bonding agent, the dentist applies the composite resin in small amounts, hardening each layer with a special light before applying the next one. With each subsequent layer, the dentist sculps the composite material to eventually resemble the wax-up model.
After completing the composite application, the dentist then uses hand tools and a dental drill to complete shaping, as well as an abrasive strip between teeth to aid future flossing. After just a few hours, the transformation is complete.
Direct veneers are durable, but not to the same extent as regular veneers or other cosmetic enhancements. They can also pick up stains over time, and may require re-treatment at some point. Still, direct veneers are a cost-effective way to improve the appearance of teeth with multiple flaws that could radically change your smile for the better.
