You’ve been embarrassed for a while now by your yellowed, dull teeth. You’re ready for a change.
There’s a simple and cost-effective way to make that change: you can temporarily brighten your smile with teeth whitening, possibly at home. But before you try it, you should first have a dental examination to find out if whitening is the right choice for you.
First off, healthy teeth with outer enamel staining are the best candidates for whitening. Teeth and gums with tooth decay or periodontal (gum) disease should be treated first before undergoing whitening. A dental exam will uncover any health issues you may have with your mouth.
In the same vein, you’ll want to consider whitening carefully if you have dental work like veneers, crowns or implants. Unlike natural teeth, these non-biological materials won’t be affected by the bleaching agent. We can discuss any potential for color mismatch between your whitened natural teeth and your dental work during your examination.
A dental exam can also uncover one other crucial fact — what kind of tooth staining you have. There are two basic types: extrinsic, staining on the outside enamel as we’ve mentioned earlier; and intrinsic, staining that originates from inside a tooth. The whitening kits you purchase from a store and even some of the whitening techniques we use in the office only diminish extrinsic, not intrinsic staining. To address an intrinsically-stained tooth requires a much more involved, invasive clinical technique only performed by dental professionals.
Finally, a dental examination is a good discussion forum for helping you decide between a home kit and a clinical procedure. While DIY kits are effective for the most part, you won’t be able to precisely control the degree of brightness like we can. This could be important if you want a specific shade of whiteness, from a more subtle and natural shade to dazzling “Hollywood” bright. Shade control could also help minimize color mismatch with dental work.
In the end, we want to help you make the best choice for teeth whitening. Even if you decide to pursue whitening at home, we can offer you valuable advice on what to look for when you buy a kit and how to use it. That alone could help ensure you get the new, bright smile you desire!

Can you have healthy teeth and still have gum disease? Absolutely! And if you don’t believe us, just ask actor David Ramsey. The cast member of TV hits such as Dexter and Arrow said in a recent interview that up to the present day, he has never had a single cavity. Yet at a routine dental visit during his college years, Ramsey’s dentist pointed out how easily his gums bled during the exam. This was an early sign of periodontal (gum) disease, the dentist told him.
“I learned that just because you don’t have cavities, doesn’t mean you don’t have periodontal disease,” Ramsey said.
Apparently, Ramsey had always been very conscientious about brushing his teeth but he never flossed them.
“This isn’t just some strange phenomenon that exists just in my house — a lot of people who brush don’t really floss,” he noted.
Unfortunately, that’s true — and we’d certainly like to change it. So why is flossing so important?
Oral diseases such as tooth decay and periodontal disease often start when dental plaque, a bacteria-laden film that collects on teeth, is allowed to build up. These sticky deposits can harden into a substance called tartar or calculus, which is irritating to the gums and must be removed during a professional teeth cleaning.
Brushing teeth is one way to remove soft plaque, but it is not effective at reaching bacteria or food debris between teeth. That’s where flossing comes in. Floss can fit into spaces that your toothbrush never reaches. In fact, if you don’t floss, you’re leaving about a thirdÂ to half of your tooth surfaces unclean — and, as David Ramsey found out, that’s a path to periodontal disease.
Since then, however, Ramsey has become a meticulous flosser, and he proudly notes that the long-ago dental appointment “was the last we heard of any type of gum disease.”
Let that be the same for you! Just remember to brush and floss, eat a good diet low in sugar, and come in to the dental office for regular professional cleanings.

If you’ve lost some teeth you may eventually want to replace them with dental implants. Implants by far are the restoration of choice due to their life-likeness and durability. But those advantages don’t come cheaply — implants can be expensive especially for multiple teeth.
If you’re forced to wait financially for implants, you still have other intermediary options like a removable partial denture (RPD). The conventional RPD has a rigid acrylic base colored to resemble gum tissue supported by a metal frame with attached prosthetic (false) teeth at the missing teeth locations. They’re held secure in the mouth through metal clasps that fit over the remaining teeth.
But these conventional RPDs can sometimes be uncomfortable to wear and don’t always cover the bottom of the gum completely. If this is a concern, you might consider an alternative: flexible RPDs. The base of this RPD is made of a form of flexible nylon rather than acrylic plastic. They’re much more lightweight but still fit securely in the mouth with thin plastic extensions rather than metal clasps. The base can also be more easily formed to cover areas where gum tissue may have receded.
While flexible RPDs hold up better to wear and tear than their conventional counterparts, they must still be maintained like any other appliance. They can accumulate plaque (bacterial biofilm) responsible for tooth decay and periodontal (gum) disease, so daily thorough cleaning is a must. And if there fit becomes loose they can be more difficult to reline or repair than other types of dentures.
They also share a common weakness with other dentures — they can’t prevent and may even stimulate bone loss. As bone ages, old cells dissolve and new ones form to take their place. As we eat and chew our teeth transmit the forces generated through the teeth to the bone to stimulate it to grow. RPDs and other dentures can’t transmit this stimulus, so the bone replaces much slower to the point that the bone volume can diminish.
That’s why it’s best to consider any RPD as a temporary solution until you can obtain an implant for a more permanent and bone-friendly option. In the meantime, though, an RPD can provide you with a great solution for both form and function for missing teeth.
If you would like more information on RPD choices, 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 “Flexible Partial Dentures: An Aesthetic Way to Replace Teeth Temporarily.”
September is National Gum Care Month. Did you know that advanced periodontal disease is the number one cause of tooth loss among adults? Periodontal disease refers to any disease that affects the structures that hold the teeth in place, including gums, ligaments and bone. In its earliest stage, called gingivitis, the gums become inflamed. When it progresses to periodontitis, both soft and hard tissues that hold the teeth in place are affected, threatening the integrity of the teeth. Some people are more susceptible to periodontal disease than others. Here are some common risk factors:
Poor oral hygiene. Plaque buildup is the primary cause of gum disease. When life gets busy, we may be less diligent about our oral care. This allows bacteria in the mouth to form a biofilm (plaque), which causes inflammation of the gums.
Heredity: Some people are genetically more predisposed to gum disease. Look at your family history. Have any of your relatives had gum disease or lost their teeth?
Pregnancy. Gums are sensitive to hormone fluctuations, and it is not uncommon for pregnant women to experience an inflammation of the gums known as “pregnancy gingivitis.” Gingivitis — characterized by red, swollen gums that bleed easily — is the beginning stage of gum disease.
Age: The chance of developing gum disease increases with age. Over 70% of Americans 65 and older have periodontitis, an advanced form of gum disease, according to the U.S. Centers for Disease Control and Prevention. This may be influenced by other diseases, medications that cause dry mouth, or other causes of plaque buildup.
Diet: Eating too many simple carbohydrates (those found in sugar, white bread, white rice and mashed potatoes, for example) is linked to chronic inflammation in the body, which increases the risk of gum disease.
Smoking: Smoking is a significant risk factor for the development and progression of gum disease. Since nicotine constricts blood vessels, smokers may not see the typical symptoms such as red, puffy, bleeding gums, so the disease may cause damage before smokers realize there is a problem with their gums.
Diabetes: Uncontrolled diabetes puts you at higher risk of periodontal disease. Not only can diabetes make gum disease worse, gum disease can make diabetes symptoms worse.
Our aim is not to scare you but to help you become aware of factors that can increase your risk of gum disease. Many of these factors are not under your control. However, you can do your part to prevent gum disease by staying on top of the things you can control. Let us know about any new medications you are taking, eat a balanced diet rich in complex carbohydrates and other nutrients and, if relevant, manage your diabetes and explore programs that will help you quit smoking.
Fortunately, good oral hygiene and regular professional cleanings can turn early gum disease around, so if you have any of the risk factors that contribute to periodontal disease, be extra diligent about your oral hygiene routine. And make sure you come in for regular dental checkups and cleanings. If you show signs of gum disease, we may recommend that you come in for more frequent cleanings.
Over the last century and a half millions of people have had a tooth cavity filled with “silver” amalgam. Perhaps you’re one of them. The use of this effective and durable filling has declined in recent years, but only because of the development of more attractive tooth-colored materials.
At the same time there’s another issue that’s been brewing in recent years about this otherwise dependable metal alloy: the inclusion of mercury in amalgam, about half of its starting mixture. Various studies have shown mercury exposure can have a cumulative toxic effect on humans. As a result, you may already be heeding warnings to limit certain seafood in your diet.
So, should you be equally concerned about amalgam fillings — even going so far as to have any existing ones removed?
Before taking such a drastic step, let’s look at the facts. To begin with, not all forms of mercury are equally toxic. The form causing the most concern is called methylmercury, a compound formed when mercury released in the environment combines with organic molecules. This is the form certain large fish like salmon and tuna ingest, which we then ingest when we eat them. Methylmercury can accumulate in the body’s tissues where at high levels it can damage various organ systems.
Dental amalgam, on the other hand, uses elemental mercury. Dentists take it in liquid form and mix it with a powder of other metals like silver, tin and copper to create a pliable paste. After it’s placed in a prepared cavity, the amalgam hardens into a compound in which the mercury interlaces with the other metals and becomes “trapped.”
Although over time the filling may emit trace amounts of mercury vapor, it’s well below harmful levels. You’re more likely to encounter “un-trapped” mercury in your diet than from a dental filling. And scores of studies over amalgam’s 150-year history have produced no demonstrable ill effects due to mercury.
Although it now competes with more attractive materials, amalgam still fills (no pun intended) a necessary role. Dentists frequently use amalgam in less visible back teeth, which encounter higher chewing pressures than front teeth. So, if you already have an amalgam filling or we recommend one to you, relax — you’re really in no danger of mercury poisoning.
