People have depended on dentures for generations—and they still do. That's because they work, both in restoring dental function and a smile marred by missing teeth.
But they have one major drawback related to bone health. That's because living bone has a life cycle: as older cells die, new ones form to take their place. The pressure generated when we chew stimulates this growth. But when this stimulus goes missing along with the teeth, the cell replacement rate slows and bone volume and density gradually diminishes.
Traditional dentures can't transmit this chewing pressure stimulus. And because they rest directly on the gum ridges, they can adversely affect the underlying bone and actually accelerate bone loss.
But implant technology potentially solves this bone loss problem with dentures by using implants rather than the gums to support them. It's a two-fold benefit: first, the implants relieve much of the irritation to the gums and bone caused by traditional dentures. Primarily, though, the implants themselves can slow or even stop continuing bone loss.
Most implants are made of titanium, not only because it's compatible with the body, but also because it has an affinity with bone. Over time bone cells grow on the titanium post imbedded in the jawbone. This process not only creates stability and durability, it can improve bone health.
In recent years dentists have incorporated implants with dentures to create two exciting treatment options. With one option, the dentist installs two or more implants in the jaw, to which a specially fitted removable denture can be attached. You would still have the ease of removing the denture for cleaning, while gaining greater stability and a reduced risk of bone loss.
The other option is a fixed denture (or bridge) attached permanently to implants. For this option, a patient's jawbone must be adequate and healthy enough to support at least four to six implants. A fixed denture is also often costlier and more complex than a removable denture, but it can feel more like real teeth. It also promotes better bone health too.
Although both options are more expensive than traditional dentures, they can pay dividends for long-term dental health. Implants could help you enjoy your new dentures and resulting smile for a long time to come.

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.”
Brushing and flossing are foundational to good oral health and an essential part of daily life. Practicing both these habits removes most disease-causing bacterial plaque from tooth and gum surfaces.
It doesn’t take much to manually perform them — a quality soft-bristle toothbrush, fluoride toothpaste and string floss. But what if you have a physical impairment that makes performing these tasks difficult to perform — or your mouth condition requires a little more “power” to adequately access and clean surfaces?
You do have power options for both brushing and flossing. Electric toothbrushes, of course, have been available since the 1950s. As with other technology, they’ve improved in quality and affordability over the last few decades. They’re available in various sizes, rechargeable or battery, and each with their own claims of cleaning ability.
The ultimate question, though, is: are they as effective at removing plaque as manual brushing? That’s been the subject of a number of comprehensive studies, including one conducted by the Cochrane Collaboration, a research organization. They evaluated a number of powered toothbrushes over various lengths of time. They concluded that some powered toothbrushes with a rotation-oscillation action had a statistically significant (though modest) reduction in plaque compared with manual toothbrushes.
As to flossing, admittedly it does take some dexterity to accomplish effectively. Traditional string flossing is also difficult if not impossible for people with braces or similar access restrictions to the teeth. An oral irrigator (or water flosser) is a viable alternative. Water flossers work by pulsating water at high pressure through special tips at the end of a handheld or countertop device. The pressurized stream penetrates between teeth and below the gums to flush away plaque.
Are water flossers effective? According to one recent study orthodontic patients were able to remove up to five times the plaque between teeth as those who used only a manual toothbrush.
When considering alternatives to your manual toothbrush or string floss, speak with us first. We’ll be happy to guide you toward the best form of brushing and flossing to do the most good in your situation.
When you visit us for your regular checkup we're examining more than your teeth and gums. We're also checking to see if you're having problems with soft tissues in and around your mouth.
Besides canker sores, rashes or other types of abnormalities, our exam may uncover strange looking lesions known as lichen planus on the inside of the mouth. These purple-tinted bumps or rash-like discolorations are named for their similarity in appearance to lichen fungi found on trees or rocks. Although these mouth sores may look odd, they're fairly rare and usually do not cause concern.
Most people don't even know they have lichen planus until it's discovered during a dental exam. If there are any symptoms, it's usually a feeling of roughness, tenderness or itching. They may increase your sensitivity to spicy or acidic foods, but rarely cause extreme pain. If they're located around the gums, you may also notice a little soreness after brushing or eating.
To confirm it is lichen planus, we need to perform a biopsy. During this procedure, we remove a tiny amount of the affected tissue and have it examined microscopically. We do this not only to determine the correct diagnosis, but also to rule out more serious problems like pre-cancerous lesions or oral cancer.
Thankfully, though, this worst case scenario is quite rare, and although the condition can't be cured, there are some things you can do to keep any discomfort to a minimum. If the lesions are irritating, we recommend using a soft toothbrush with gentle brushing action. You may also want to limit or avoid spicy or acidic foods like citrus, tomatoes, hot peppers and caffeinated drinks. Managing stress can also help. For some extreme conditions, we can prescribe a topical steroid to help relieve discomfort.
If you notice any of the above symptoms, be sure to contact us or point it out at your next appointment. Once we know what we're dealing with, we can take steps to treat you.

Although energy and sports drinks have different purposes, they have one thing in common: they often contain added citric and other acids to improve taste and prolong shelf life. Their high acid content can harm tooth enamel.
Although enamel is the strongest substance in the body, acid can dissolve its mineral content. And although saliva neutralizes acid after eating or drinking and helps restore lost minerals to the enamel, it may not be able to keep up if the mouth remains acidic for a prolonged period of time.
That could happen with both beverage types. While energy drinks have higher acid levels than sports drinks, both are high compared with other beverages.
A recent laboratory experiment studied the two beverages’ effect on tooth enamel. The researchers submerged samples of enamel in six different beverage brands (three from each category) for fifteen minutes, and then in artificial saliva for two hours to simulate mouth conditions. They repeated this cycle four times a day for five days.
At the end of the experiment the enamel in the energy drinks lost on average 3.1 % of their structure, while the sports drink samples lost 1.5%. Although energy drinks appeared more destructive, the acid in both beverages caused enamel damage. Although there are other factors to consider in real life, the experiment results do raise concerns about both beverages’ effect on dental health.
You can, however, minimize the potential harm to your enamel from energy or sports drinks. First, try other beverage choices lower in acid; water, for example, is a natural hydrator and neutral in pH. Try to only drink energy or sports beverages at mealtimes when your saliva is most active. And after drinking, rinse your mouth out with water to dilute any remaining acid.
And although it sounds counterintuitive, wait about an hour to brush your teeth after drinking one of these beverages. Your enamel can be in a softened state before saliva can re-mineralize it, so brushing earlier could remove tiny amounts of enamel minerals.
Taking these steps with energy or sports beverages could help you reduce the chances for enamel erosion. Doing so may help you avoid unnecessary damage to your teeth and overall dental health.
