X-ray imaging is such an intricate part of dentistry, we usually don't think twice about it. Without it, though, the fight against dental disease would be much harder.
At the same time, we can't forget that x-rays are a form of electromagnetic radiation that can penetrate human tissue. It's that very quality and the difference in the absorption rate between denser bone and teeth and softer diseased tissue that makes disease diagnosis possible.
But this same penetrative power can potentially harm the tissues it passes through. For that reason when practicing any form of x-ray diagnostics, dentists follow a principle known as ALARA, an acronym for "As Low As Reasonably Achievable." In lay terms ALARA means getting the most benefit from x-rays that we can with the lowest dose and exposure time possible.
While practicing ALARA with x-rays is important for patients of any age, it's especially so for children who are more sensitive to radiological energy given their smaller size and anatomy. We can't use the same settings, dosages or exposure times with them as with an adult.
To protect children, dentists have developed techniques and protocols that lessen their exposure time and rate, while still providing usable images for diagnosing disease. The bitewing is a good example of safe and effective pediatric x-ray imaging.
A bitewing is a plastic device holding exposable film that patients bite down on and hold in their mouth while x-raying. The x-rays pass through the teeth and gums and expose the film behind them on the bitewing. Using a bitewing we can capture a set of two to four radiographs to give us a comprehensive view of the back teeth, while exposing the child less radiation than they normally receive daily from background environmental sources.
This and other advances in equipment and digital imaging greatly reduce the amount of radiation patients receive during x-rays. If, though, you're still concerned about your child's x-ray exposure, talk with your dentist who can explain in more detail the x-ray safety protocols they follow. Just like you, they want your child to be as safe as possible while still benefiting from the diagnostic power of x-rays.

A root canal treatment is a highly effective way to save a deeply decayed tooth. Sometimes, though, complications make it difficult or even impossible to perform the traditional procedure. In those cases, we may need to use a different option.
Tooth decay becomes an imminent threat to a tooth's survival if it works its way into the pulp, the innermost layer of a tooth. It's only a short advancement from there into the roots by way of the root canals.
In a typical root canal treatment, we access the pulp by drilling a small hole in the biting surface of a back tooth or the back side of a front tooth. We remove all the tissue within the pulp and fill it and the root canals with a special filling to prevent re-infection. After sealing the access hole, we cap the tooth with a crown to further protect it.
Although root canal treatments have a high success rate, re-infection can still occur. Often, a second root canal will save the tooth from the new infection.
In some cases, though, using the traditional procedure might do more harm than good. It's possible we may find extra canals previously undetected branching out from the primary canal at the root end. Canals can calcify and narrow, making them extremely difficult to fill. Subsequent dental work may also prove troublesome: we would have to take the restoration apart, which could further weaken the tooth.
The alternative is a procedure known as an apicoectomy. Instead of accessing the pulp through the crown, we access the root end through the gum tissue. We then focus on removing infected tissue at the tooth's root end, along with a tiny amount of the root tip. We then place a small filling at the end of the root canal (essentially plugging it up) to prevent further infection. We may also perform grafting to encourage bone growth in any voids left by the procedure.
Endodontists, specialists in root canals, have the advanced training and specialized equipment to perform an apicoectomy. With their expertise, they may be able to save your tooth with this specialized procedure when a root canal treatment won't work.

If you're well past your teen years, you probably have several reasons for not straightening your crooked smile: the expense, the time and the embarrassment of being a 30-, 40- or 50+- something wearing braces. But we have five reasons why adult orthodontic treatment can be a smart choice: Tom Cruise, Kathy Bates, Carrie Underwood, Danny Glover and Faith Hill.
That's right: Each of these well-known entertainers and performers—and quite a few more—underwent treatment to improve a poor dental bite. And not as teenage unknowns: Each on our list wore braces or clear aligners as famous adults (the paparazzi don't lie!).
Here are a few of the reasons why these celebrities chose to change their smile through orthodontics—and why you can, too.
Age isn't a factor. Straightening misaligned teeth isn't reserved only for tweens and teens—there are a growing number of adults well into their middle and senior years undergoing orthodontic treatment. As long as your teeth are relatively sound and your gums are healthy, it's altogether appropriate to undergo bite correction at any age.
A boost to your dental health. Gaining a more attractive smile through orthodontics is in some ways an added benefit. The biggest gain by far is the improvement straightening your teeth can bring to your long-term health. Misaligned teeth are more difficult to keep clean of dental plaque, which can increase your disease risk. They also may not function as well as they should while chewing food, which can affect your digestion.
Traditional braces aren't the only way. If the thought of displaying all that hardware makes you cringe, it's not your only option. One of the most popular alternatives is clear aligners, custom plastic trays that are nearly invisible on your teeth—and you can take them out, too. Another method growing in popularity are lingual braces: All the hardware is behind the teeth and thus out of sight. And you can, of course, opt for traditional braces—just ask Tom Cruise!
Oh, yes—a new smile! Orthodontics was truly the first “smile makeover.” It can improve your appearance all by itself, or it can be part of a comprehensive plan to give you an entirely new look. While the gains to your health are primary, don't discount what a more attractive smile could do for you in every area of your life.
The best way to find out if orthodontics will work for you is to visit us for an initial exam and consultation. Just like our A-list celebrities, you may find that orthodontics could be a sound investment in your health and self-confidence.
