X-rays are an important diagnostic tool in dentistry because of their ability to penetrate and pass through body tissues. Because they penetrate at different speeds depending on tissue density (shorter and thus darker on exposed film for soft tissues, longer and lighter for hard tissues like bone or teeth), we’re able to detect decay which appear as dark areas on x-ray film.
Without x-rays, the early detection and diagnosis of dental problems would be quite difficult. But despite its obvious benefits, it’s still a form of released energy that exposes patients to a certain amount of radiation. Since the potential health risk from radiation depends on the amount released (the dosage) and for how long and often a person is exposed, we must determine if the dosage and frequency from dental x-rays is a cause for concern.
It’s a common misconception to view any radiation exposure as dangerous. The truth is, however, we’re all exposed daily to radiation from the natural environment — about 2 to 4.5 millisieverts (the dosage measurement for radiation exposure) a year, or about 10 microsieverts (one-thousandth of a millisievert) every day.
In comparison, radiation exposure from routine dental x-rays is a fraction of this if measured over time. A set of four bitewing images of the back teeth produces 4 microsieverts of radiation, less than half the average daily exposure. One of the most comprehensive x-ray sets, a full mouth series of 18-20 images using “D” speed film, results in an exposure of 85 microsieverts, equaling about a week of normal radiation exposure.
These thoroughly researched rates help demonstrate that regular dental x-rays are relatively safe. What’s more, x-ray technology has continued to advance since first used in the mid-20th Century. With innovations in film and digital processing, today’s equipment produces only 80% of the radiation exposure of earlier machines. In effect, we’ve increased our capabilities to more accurately detect and diagnose issues through x-rays, while lowering the amount of radiation exposure.
Of course, a person’s annual exposure rate may differ from others. If you have concerns for yourself or your family about x-ray radiation exposure, please feel free to discuss this with us. Our primary goal is to improve your oral health without undue risk to your health in general.

Chronic stress is like a tea kettle on the boil—all that “steam” has to go somewhere. We often do this through behaviors like biting our nails, binging on comfort food—or grinding our teeth. That latter habit, however, could have a detrimental effect on teeth, including excessive enamel wear or even fractures.
Also known as bruxism, teeth grinding is the forceful and often involuntary contacting of teeth that often generates abnormally high chewing forces. While not considered a relatively big problem with young children, it can be if you’re an adult. While there could be other causes, chronic stress is often a prime factor for adults with bruxism.
While teeth grinding can occur during the day when you’re awake, it often occurs at night during sleep and may be associated with other sleep disorders like snoring. Although you might not be consciously aware of a grinding episode as it happens, you may notice its effects the next morning, including sore jaws or headaches. Over time, your dentist may begin noticing its effects on your teeth.
So, how can you lessen teeth grinding? For starters, if you’re a tobacco user, quit the habit. Many studies indicate tobacco users report twice the incidence of teeth grinding as non-users. Excessive caffeine, alcohol or drug use can also contribute.
People have also found it helpful to address chronic stress through a number of relaxation techniques like meditation, more relaxing bedtime preparation, bio-feedback or therapy to “de-stress.” Although there’s not a lot of empirical evidence for these techniques’ effectiveness, there’s much anecdotal data from people who’ve found stress relief from them.
There’s also a dental treatment using an occlusal guard that, while not stopping bruxism, can help prevent dental damage. Usually worn during sleep, the custom-made guard fits over the teeth of one jaw, usually the upper. Its high impact plastic prevents the teeth from making solid contact, thus reducing the biting force. You may also be able to reduce bruxism effects through dental work and orthodontics,
You and your dentist can explore the options to find the right treatment strategy for you. By taking action now, you may avoid much more extensive—and expensive—problems with your teeth down the road.

Academy Award-winning actress Kathy Bates knows how important it is to present your best face to the world — and one of the most important features of that face is a beaming smile. But there came a point when she noticed something was a little off. “I've always had good teeth, but it seemed to me as I was getting older that they weren't looking as good,” Kathy explained in a recent interview with Dear Doctor magazine.
That's when she decided it was time to take action. Kathy had orthodontic treatment when she was in her fifties, and she keeps her smile bright with tooth whitening treatments. She uses a kit provided by her dentist with a safe, effective whitening solution.
Of course, a bright, healthy smile looks great anywhere — whether you're on the red carpet or “off the grid.” And you don't have to be a Hollywood star to have professional whitening treatments. In fact, teeth whitening is one of the most popular and affordable cosmetic treatments modern dentistry offers.
The basic options for professional teeth whitening include in-office bleaching or take-home kits. Both types of dentist-supervised treatments offer a safe and effective means of getting a brighter smile; the main difference is how long they take to produce results. A single one-hour treatment in the office can make your teeth up to ten shades lighter — a big difference! To get that same lightening with at-home trays, it would take several days. On the plus side, the take-home kit is less expensive, and can achieve the same results in a bit more time.
It's important to note that not all teeth can be whitened with these treatments. Some teeth have intrinsic (internal) stains that aren't affected by external agents like bleaches. Also, teeth that have been restored (with bonding or veneers, for example) generally won't change color. And you can't necessarily whiten your teeth to any degree: Every tooth has a maximum whiteness, and adding more bleach won't lighten it beyond that level. Most people, however, find that teeth whitening treatments produce noticeable and pleasing results.
What about those off-the-shelf kits or in-the-mall kiosks? They might work… or they might not. But one thing's for sure: Without a dentist's supervision, you're on your own. That's the main reason why you should go with a pro if you're considering teeth whitening. We not only ensure that your treatment is safe — we can also give you a realistic idea of what results to expect, and we will make sure that other dental problems aren't keeping you from having a great-looking smile.
How often does Kathy Bates see her dentist for a checkup and cleaning? “I go about every four months,” she noted. “I'm pretty careful about it.” And if you've seen her smile, you can tell that it pays off.
