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.

Other than tooth decay, children don't encounter dental disease to the extent adults do. But injuries are another story: More than 5 million teeth are knocked loose each year, and a high percentage involve children. Roughly a third of these and similar children's injuries are sports-related.
April is National Facial Protection Month: Several oral and facial health organizations, including the American Association of Orthodontists, have joined together to raise awareness about the risks of injury to the face and mouth, especially among children. Many of these injuries have long-term consequences with lifetime treatment costs in the thousands of dollars.
But as the name implies, this awareness month is also about protection—what you can do to help your child avoid a costly and devastating dental injury. Top of the list: Have your child wear an athletic mouthguard during all contact sports activities (including practices).
The National Federation of State High School Associations mandates mouthguard wear for football, lacrosse, and ice and field hockey. But those aren't the only sporting activities where a mouthguard should be standard equipment: In fact, basketball has more orofacial injuries each year than any other sport. Generally, mouthguards should be worn for any sports activity that involves potential contact with other players or objects.
There is a variety of mouthguard choices, but most fall into two basic categories, “boil and bite” and custom-made. The former, readily available in retail sports stores, get their name from the procedure employed when first purchased to adjust their fit to an individual player. Out of the package, they should be soaked in hot or boiling water until softened, and then placed in the wearer's mouth to bite down on. After they cool, they'll retain that bite pattern.
Boil and bite guards are relatively inexpensive, but the fit isn't as precise as a mouthguard that is custom-made by a dentist. This can lead to comfort issues—and players are less likely to wear an uncomfortable mouthguard.
Custom mouthguards, on the other hand, have a more accurate fit, allowing them to be thinner and more comfortable. They also provide the highest level of protection against blows to the face and mouth. These are more costly than boil and bite guards, and younger athletes may need a replacement every few years to accommodate jaw growth development. But compared to the physical, emotional and financial cost of a dental injury, custom mouthguards are worth the investment.
A mouth or face injury can happen in an instant and result in damage that can have lingering effects for years. For the best protection, see that your star athlete has and wears a custom mouthguard.
Are you one of the millions Americans who wear a full or partial denture? If so, you know that proper denture fit and cleanliness keep your mouth healthy and functional. At Dr. Ron Williamson's office in Berkley, MI, patients learn denture care for bright, comfortable smiles.
What are dentures?
Worn by edentulous people for generations, dentures replace one, several or even all teeth on the upper and/or lower arch. Most people are familiar with the traditional partial made of a few acrylic teeth on a metal framework. Clasps or attachments hold it to remaining teeth.
Full dentures replace all teeth--either immediately, or after gums and bone have healed after dental extractions. Implant-supported dentures may be fixed or removable. Either way, they offer superior stability and strengthen the jaw bone, too.
When you come to his Berkley, MI, office, Dr. Williamson will create a denture plan right for your mouth, appearance and budget. A well-respected dental lab fabricates your appliance according to your dentist's instructions. Precision fit and quality materials ensure you of well-fitting denture which lasts with good care.
Many denture wearers don't care for their prosthetics carefully. The results are damaged dentures, poor fit and intra-oral conditions such as stomatitis, irritated gums, and impaired biting, chewing and speech.
So, it benefits you and your smile to have a daily denture routine. Here's what the ADA recommends:
- Clean your prosthetic daily with a quality denture soak, paste or powder. Use a soft toothbrush to remove plaque and stains.
- If you take your denture out at night, keep it in water to avoid warping.
- Apply a denture adhesive or wafer to maximize denture fit and stability as needed.
- See Dr. Williamson right away if you notice changes in denture fit, see deep stains or cracks or develop sores or any degree of redness and swelling.
- Use special dental implant floss and/or a WaterPik device to keep food particles from collecting around the junctures between implants and dentures.
Most dentures perform very well for the first five years, says the ADA, but may begin to deteriorate after that. Also, your mouth, and therefore denture fit, gradually change over time. So, be sure to see Dr. Williamson and his team twice a year for a check-up and cleaning. He'll examine the condition of your denture and let you know when a re-line or new appliance is needed.
A wonderful smile
Denture wearers definitely can have one. Just take care of your mouth and your denture every day. For questions or concerns about your dentures, please contact Dr. Ron Williamson at his Berkley, MI, dental practice: (248) 399-4455.
If you're the principal caregiver for an older person, you may have already faced age-related health challenges with them. Good preventive care, however, can ease the impact of health problems. This is especially true for their teeth and gums: with your support you're loved one can have fewer dental problems and enjoy better health overall.
Here are a number of things you should focus on to protect an older person's dental health.
Hygiene difficulties. With increased risk of arthritis and similar joint problems, older people may find brushing and flossing more difficult. You can help by modifying their toothbrush handles with a tennis ball or bicycle grip for an easier hold, or switch them to an electric toothbrush. A water flosser, a device that uses a pressurized water spray to remove plaque, may also be easier for them to use than thread flossing.
Dry mouth. Xerostomia, chronic dry mouth, is more prevalent among older populations. Dry mouth can cause more than discomfort—with less acid-neutralizing saliva available in the mouth, the risk for dental diseases like tooth decay or periodontal (gum) disease can soar. To improve their saliva flow, talk with their doctors about alternative medications that cause less dry mouth; and encourage your loved one to drink more water and use products that help boost saliva flow.
Dentures. If your older person wears dentures, be sure these appliances are being cleaned and maintained daily to maximize their function and reduce disease-causing bacteria. You should also have their dentures fit-tested regularly—chronic jawbone loss, something dentures can't prevent, can loosen denture fit over time. Their dentures may need to be relined or eventually replaced to ensure continuing proper fit and function.
Osteoporosis. This common disease in older people weakens bone structure. It's often treated with bisphosphonates, a class of drugs that while slowing the effects of osteoporosis can cause complications after certain dental procedures. It's a good idea, then, for an older person to undergo any needed dental work before they go on osteoporosis medication.
Keep alert also for any signs of dental disease like unusual spots on the teeth or swollen or bleeding gums. Visiting the dentist for these and regular dental cleanings, checkups and oral cancer screenings could prevent many teeth and gum problems.

You probably know practicing healthy dietary and lifestyle habits can help prevent tooth decay and periodontal (gum) disease. But good habits could also lower your risk for a more dangerous type of disease — oral cancer.
There are several risk factors for oral cancer, including those you can't do much about like your genetic makeup or unknown elements in the environment. But there are factors you can influence with your actions.
You're probably familiar with the links between tobacco use (both smoked and smokeless) and oral cancer. But excessive alcohol use could also increase your risk, as can risky sexual behavior that could expose you to human papilloma virus (HPV) 16.
And what you eat — or don't eat — could also influence your cancer risk. Research over the last half century has uncovered a link between diet and cancer. Cancer development seems to begin with damage to DNA, the genetic material that “tells” each of our cells what it is and what it does in the body. Substances called carcinogens found in the environment — including the foods we eat — can damage our DNA and open the door for cancer to development.
But some foods also contain elements that protect our DNA from carcinogenic damage. Some of these are known as antioxidants, which protect cells from unstable molecules called free radicals. You'll find antioxidants, as well as other protective substances like fiber, vitamins and lycopene in plant-based foods, particularly fruits and vegetables.
Eating a plant-based diet also means you'll eat fewer foods that contribute to the rise of free radicals like saturated fat, animal protein and nitrates (a chemical that occurs in some food processing). A healthy diet, along with quitting tobacco use and moderating alcohol consumption, will help not only preventing decay or gum disease, it will also drastically lower your risk for oral cancer.
