Although highly preventable, total tooth loss continues to affect millions of people worldwide, harming their nutrition, health and social standing. In the United States alone, a quarter of adults between 65 and 74 suffer from total tooth loss.
Fortunately, there are a number of ways to restore lost teeth, including fixed bridgework and dental implants. These fixed solutions, though, can put a strain on finances; implants in particular require a minimum amount of bone in the jaw, which may not be present in people with extensive tooth loss. In these cases, removable dentures, time-tested and affordable, are a viable option.
While the technology is simple, adaptable and effective, creating custom-fitted dentures is a painstaking process. It begins with an impression mold of the patient’s jaw ridges that once supported the natural teeth. A dental lab technician uses the impression to fashion a life-like plastic resin base, making sure the final dimensions won’t interfere with the patient’s cheeks, lips, and jaw movement.
The prosthetic (artificial) teeth, each chosen to match the patient’s facial structure and past appearance, are then carefully positioned on the base. Teeth positioning on each denture arch must also balance with the opposing arch to assure a good bite. Once delivered, the dentist may make other adjustments to assure they fit comfortably within the patient’s mouth.
Dentures also require regular care and maintenance to ensure a continuing good fit and an overall healthy mouth. Your gums will still be susceptible to disease, so cleaning and maintaining both your dentures and the mouth’s soft tissues is an ongoing necessity.
The lack of natural teeth can also lead to more bone loss, which can cause the dentures to lose their accurate fit and make them uncomfortable to wear. To remedy this, we can add more resin material to the dentures to refit them or, in extreme cases of poor fit, create a new denture to match current gum contours. Alternatively, we can install a few dental implants that will support the denture instead of the gum ridges, which would inhibit further bone loss.
To learn whether dentures could be a good option for you, we’ll first need to conduct a thorough examination of your mouth. It could be this original tooth replacement system will bring back the teeth and smile you’ve lost.

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.

Fans of the legendary rock band Steely Dan received some sad news a few months ago: Co-founder Walter Becker died unexpectedly at the age of 67. The cause of his death was an aggressive form of esophageal cancer. This disease, which is related to oral cancer, may not get as much attention as some others. Yet Becker's name is the latest addition to the list of well-known people whose lives it has cut short—including actor Humphrey Bogart, writer Christopher Hitchens, and TV personality Richard Dawson.
As its name implies, esophageal cancer affects the esophagus: the long, hollow tube that joins the throat to the stomach. Solid and liquid foods taken into the mouth pass through this tube on their way through the digestive system. Worldwide, it is the sixth most common cause of cancer deaths.
Like oral cancer, esophageal cancer generally does not produce obvious symptoms in its early stages. As a result, by the time these diseases are discovered, both types of cancer are most often in their later stages, and often prove difficult to treat successfully. Another similarity is that dentists can play an important role in oral and esophageal cancer detection.
Many people see dentists more often than any other health care professionals—at recommended twice-yearly checkups, for example. During routine examinations, we check the mouth, tongue, neck and throat for possible signs of oral cancer. These may include lumps, swellings, discolorations, and other abnormalities—which, fortunately, are most often harmless. Other symptoms, including persistent coughing or hoarseness, difficulty swallowing, and unexplained weight loss, are common to both oral and esophageal cancer. Chest pain, worsening heartburn or indigestion and gastroesophageal reflux disease (GERD) can also alert us to the possibility of esophageal cancer.
Cancer may be a scary subject—but early detection and treatment can offer many people the best possible outcome. If you have questions about oral or esophageal cancer, call our office or schedule a consultation. You can learn more in the Dear Doctor magazine article “Oral Cancer.”
