RadiationExposurefromDentalX-RayImagingIsntaCauseforConcern

Your dental care would be much more limited without our ability to see “below the surface” with x-ray imaging. But since x-rays passing through the body are a form of radiation, could your exposure from them be hazardous to your health?

It depends on exposure dosages and, of course, the amount you have been exposed to over your lifetime. But, decades of research have demonstrated that exposure to dental x-rays during your regular office visits are only a fraction of the radiation you normally encounter from the natural environment every year.

X-rays have the ability to pass through body tissues, but at different rates for soft tissue like skin and muscle and hard tissue like bone. This effect creates shadows on exposed film; the differentiation is in such detail that a trained technician can interpret not only internal structures, but defects such as fractured bone or, in the case of dentistry, signs of tooth decay and bone loss from gum disease.

But like other energy sources in our environment, x-rays do emit radiation that in high doses can be dangerous to living tissue. The amount of exposure is measured in millisieverts (mSv), a unit that allows for comparison of doses from different sources of radiation. Scientists have calculated that we’re normally exposed to between 2 and 4.5 mSv every year.

By contrast, a single digital periapical image taken of a tooth is equal to 1 microsievert (μSv), or one thousandth of an mSv; a full mouth series (between 18 and 20 images) creates an exposure of 85 μSv, or 85/1000 of one mSv. In addition, advances in technology have further reduced the radiation exposure from x-ray imaging. For example, digital imaging has reduced exposure during full mouth x-rays from seven to ten days of equal exposure from normal background radiation to half a day, and with no loss in image quality.

In effect, dental x-rays pose little to no risk for patients. Still, understanding that x-ray imaging does expose patients to radiation, dentists follow certain protocols and safety precautions. For example, dentists will place a lead apron around their patients’ chest area during an x-ray exposure.

As your dentist, we’re happy to address any concerns you may have about x-ray radiation exposure. But rest assured, the x-ray devices used in your dental care, so necessary in the fight against tooth decay and other diseases, are safe and reliable.

If you would like more information on the use of x-ray technology and safety, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine article “X-Ray Frequency and Safety.”

HowTaylorHicksKeepsHisSmileBright

Like many who have risen to the top tier in show business, singer Taylor Hicks found that he needed a few things (besides talent, of course) to really succeed: a willingness to seek out opportunities and work hard; a unique and energetic stage presence; and a bright, appealing smile.

“Everyone wants to have a great smile,” Hicks recently told Dear Doctor magazine. “In my business, it’s one of the most important things. A lot of what I do is smiling and having fun, being in front of the camera and taking pictures.”

To help him keep his smile sparkling, Hicks opts for in-office whitening treatments from his dentist. These treatments are a safe, quick and effective way to lighten teeth by 3 to 8 shades in a single one-hour visit. Best of all, you don’t have to be an American Idol winner or a Las Vegas headliner to take advantage of them — in fact, we offer them right here in our own office.

Why choose in-office treatments instead of take-home trays (or over-the-counter products)? While each system can be effective at lightening teeth to some degree, the in-office method offers several distinct advantages. For one, it’s the fastest way to get your teeth as bright as they can be; the same lightening that can be achieved in one office visit could take a week when done at home, using custom-made trays and dentist-supplied bleaching solutions — and several weeks with over-the-counter products! So if your time is limited, in-office treatment is the way to go.

Plus, in-office treatments are performed under our direct supervision. That means we can safely use the most powerful whitening gels, and achieve the maximum control over the result. This can be important when you have crowns or replacement teeth such as implants, which Hicks has. Artificial crowns don’t whiten like natural teeth, so it’s important to get just the right degree of lightening to produce an evenly bright smile.

The bottom line, of course, is the result: a dazzling white smile. “In entertainment, a big, pearly white smile makes a difference,” Hicks said. But you don’t have to be an entertainer to enjoy the benefits of a brilliant smile — we do it for plenty of “regular folks” too.

So if your smile could use a little brightening, why not call us and schedule an appointment for whitening treatment? You can learn more in the Dear Doctor magazine articles “Teeth Whitening” and “Important Teeth Whitening Questions Answered.”

ldquoPreplessrdquoPorcelainVeneersAreTheyRightForYou

Designing a better smile sometimes requires a change in the size, shape, or color of your teeth. Porcelain laminate veneers (thin layers of dental ceramic material) enhance your appearance by replacing the natural enamel on the outside of your teeth. A veneer is physically bonded to the surface of a tooth, in essence, becoming part of it.

Traditionally, a small amount of the natural tooth enamel is drilled away to allow room for the veneer. But today, in some circumstances, it is possible to use an approach where enamel reduction or preparation is not necessary because the veneers can be bonded directly onto the tooth's natural surface. These are called “Prepless” or “No-prep” veneers, and are used to create aesthetically pleasing and natural looking restorations. An advantage of the prepless procedure is that the process is reversible so that you can give your new smile a “test drive.”

You may be a good subject for Prepless veneers if:

  • Your smile is narrow because the teeth in the sides of your smile are positioned inward and do not show from a frontal view.
  • There is spacing between your teeth, and the teeth appear too small.
  • You have a fairly common genetic condition in which one or both of the teeth directly next to the two upper front teeth are very small and peg-shaped.
  • There is an imbalance between the size of your lips and teeth (large lips and small teeth), which are not in proportion to show off your best smile.

Prepless veneers are probably not for you if:

  • Your teeth are not aligned properly in your bite.
  • Your teeth are very crowded, resulting in poor facial profile.
  • Your teeth are already relatively large or positioned forward.

In these cases you may need to have some form of orthodontic treatment to move your teeth into better position. Sometimes veneers can be used to create an illusion of proper tooth alignment, but some amount of tooth reduction may be required.

We can assess whether prepless veneers are right for you. There is no substitute for an expert dentist's talent and expertise with the various cosmetic techniques available today. These skills combined with a thorough diagnostic evaluation, and a clear understanding of your goals, are the keys to providing you with a successful and beautiful smile.
