MinimizingX-RayExposureRisksinChildrentoMaximizeBenefits

X-ray diagnostics have revolutionized our ability to detect early or hidden cavities, paving the way for better dental care. But x-ray exposure also increases health risks and requires careful usage, especially with children.

A form of invisible radiation, x-rays penetrate and pass through organic tissue at varying rates depending on the density of the tissue. Denser tissues such as teeth or bone allow less x-rays to pass through, resulting in a lighter image on exposed film; less dense tissues allow more, resulting in a darker image. This differentiation enables us to identify cavities between the teeth — which appear as dark areas on the lighter tooth image — more readily than sight observation or clinical examination at times.

But excessive exposure of living tissue to x-ray radiation can increase the risk of certain kinds of cancer. Children in particular are more sensitive than adults to radiation exposure because of their size and stage of development. Children also have more of their lifespan in which radiation exposure can manifest as cancer.

Because of these risks, we follow an operational principle known as ALARA, an acronym for “As Low As Reasonably Achievable.” In other words, we limit both the amount and frequency of x-ray exposure to just what we need to obtain the information necessary for effective dental care. It’s common, for example, for us to use bitewing radiographs, so named for the tab that attaches the exposable film to a stem the patient bites down on while being x-rayed. Because we only take between two and four per session, we greatly limit the patient’s exposure to x-rays.

Recent advances in high-speed film and digital equipment have also significantly reduced x-ray exposure levels. The average child today is exposed to just 2-4 microsieverts during an x-ray session — much less than the 10 microsieverts of background radiation we all are exposed to in the natural environment every day.

Regardless of the relative safety of modern radiography, we do understand your concerns for your child’s health. We’re more than happy to discuss these risks and how they can be minimized while achieving maximum benefits for optimum dental health. Our aim is to provide your child with the highest care possible at the lowest risk to their health.

ChristieBrinkleysTipsonToothWhitening

Christie Brinkley's world-famous smile has graced the covers of countless magazines for over 30 years. In fact, in her own words from an interview with Dear Doctor magazine, the supermodel said, “I think my smile was really my passport to success in the modeling industry.” And while most of her smile's appeal comes naturally, Christie does give it a boost with good oral hygiene, regular dental checkups and tooth whitening. As Christie says, “When it comes to teeth, keep it as natural as possible. Do not go overboard on whitening. You want your teeth to compliment your face…your friends should not be required to wear sunglasses when you smile!”

Aside from some potential minor side effects such as tooth sensitivity, whitening teeth through bleaching is a relatively inexpensive way to brighten your smile conservatively and successfully. There are three common methods, as described below:

  • An external or vital approach where “vital” (living) teeth are bleached through direct contact to the tooth's surface.
  • An internal or non-vital approach where the tooth is whitened from the inside during a root canal treatment.
  • A combination approach in which both internal and external bleaching techniques are used.

But what causes teeth to become discolored?

Tooth discoloration can be caused by a traumatic blow to your teeth resulting in nerve tissue (pulp) death. However, there can be many other causes: consuming or using products that stain the teeth such as coffee, tea, cola, tobacco products and red wine, to name just a few. Aging is another factor, as it results in changes in the mineral structure of the tooth as the enamel, the outermost layer, loses its beautiful and youthful translucency. Other causes include exposure to high levels of fluoride; tetracycline, an antibiotic, administered during childhood; inherited developmental disorders and jaundice in childhood; and tooth decay.

The good news is that we routinely brighten smiles through tooth whitening. To learn more about brightening your smile, continue reading the Dear Doctor magazine article “Teeth Whitening.” Or if you are ready to have your teeth professionally whitened, contact us today to schedule an appointment so that we can conduct a thorough examination and discuss your whitening treatment options.

Dentures Are Coming Holland MI

How much do you really know about Revolutionary War hero and famous disturber-of-the-peace Paul Revere? Take this quiz and find out! True or False:

  1. Paul Revere cried “The British are coming!”
  2. Paul Revere rode to Concord, Massachusetts.
  3. Paul Revere practiced dentistry.

The first two answers are false: Revere, like most colonists, considered himself British at the time (but might have said “the regulars” are coming); and he never made it as far as Concord, though one of his midnight-riding companions did. The last statement, however, is true: When things got slow in his regular trade of silversmithing, Revere hung out a shingle to broadcast his skills as a dentist.

“Paul Revere can fix [teeth] as well as any surgeon dentist who ever came from London, he fixes [dentures] in such a manner that they are not only an ornament but of real use in speaking and eating,” his advertisement in a Boston newspaper is supposed to have read. Revere specialized in fitting dentures made of metal and walrus ivory in his patient’s mouths. (There is no record, however, that he ever worked on George Washington’s false teeth.)

The practice of dentistry has come a long way since 1776. But the ideal set of dentures — one that’s both aesthetically pleasing and fully functional — remains a valid goal today. But now, instead of going to a metalworker, you’ll visit a denture specialist: your dentist.

We understand that dentures need to have a perfect, comfortable fit so they can do their work. That’s why we take the time to make an individual mold of your mouth as the first step of the process. Then we choose prosthetic teeth in the shape, size and shade that’s right for you. When everything is satisfactory, the dentures will be custom-fabricated in a dental laboratory using high-quality materials that are lifelike and durable. Finally, we will make sure that your new dentures look, feel and function the way they should.

If you have older dentures that no longer fit as they should, come in to our office for a check-up. It’s sometimes possible to repair or re-line dentures; in other cases, it’s best to have a new set made. Ill-fitting dentures aren’t just uncomfortable — they can also lead to oral infections and nutritional difficulties.

For more information about dentures or denture repair, please contact our office to schedule a consultation. You can learn more in the Dear Doctor magazine articles “Loose Dentures” and “Removable Full Dentures.”
