With all the new tooth-colored fillings for cavities, it's easy to overlook metal amalgam. While this mainstay of dental care for over a century might not be as attractive as composite resins or glass and resin ionomers, it still has the advantage of strength and durability.
Amalgam is a stable metal alloy usually made up of silver, tin, copper and mercury. The metals are proportioned and mixed precisely to guard against “free” mercury molecules, which could pose a health hazard. The mixture is pliable at first, but then sets hard once molded into the prepared area of the tooth.
Besides strength, amalgam's other advantages include low cost, high resistance to wear and biocompatibility (not toxic to the body or allergy-producing). At the same time, it can require more tooth structure removal to accommodate a filling and cause higher sensitivity to temperature for a while after installation. Its main disadvantage, however, is appearance — it's now considered unacceptable from an aesthetic point of view to use it in visible areas like the front teeth.
Because of this, materials resembling natural tooth color are coming into vogue, especially as their strength improves. Still, dental amalgam continues to play a useful role, especially in less visible back teeth with higher chewing forces.
One past concern about dental amalgam is the inclusion of mercury in the alloy. As mentioned before, mercury is hazardous in a “free” form when not knit microscopically with other metals; as such it can emit a vapor that could enter the bloodstream and damage the nervous system. But after several studies by various organizations, the American Dental Association has concluded amalgam's precise mixture prevents the mercury from taking this form: although some vapor is given off during chewing it's far too low in concentration to pose any danger.
Dental amalgam continues to be an effective choice for fillings. Whether it's the right choice for you will depend on the type and location of a tooth to be filled, and whether durability is a higher concern than appearance. If we do recommend an amalgam filling, you can be assured it's a safe and lasting choice.

Although preventable, the occurrences of tooth decay are all too common. Yet decay doesn’t appear out of the blue: certain mouth conditions set the disease in motion.
Here are a few signs of such conditions to watch for — they could be telling you you’re at higher risk for tooth decay.
Visible plaque. Plaque is a thin film of bacteria and food accumulating on tooth surfaces and a prime haven for causing periodontal disease. If you actually see it — a crusty, yellowish film — that means there’s a large, unhealthy amount of it. It’s essential to remove it daily through diligent brushing and flossing and more thorough office cleanings at least twice a year.
Poor saliva flow. One of this bodily fluid’s functions is to neutralize mouth acid, usually thirty minutes to an hour after we eat. If saliva flow is inadequate, though, acid levels may remain high and endanger the enamel. “Dry mouth” can occur from a number of causes, including some medications and chemotherapy treatments. It’s important to alleviate the cause if possible by changing medications or stimulating saliva flow through other means.
Tooth shape and appliances. Largely determined by heredity, your teeth contain unique, tiny grooves known as pits and fissures that could harbor plaque. Certain appliances like retainers, braces or night guards can inhibit saliva flow and cause your teeth to retain more plaque. It’s important then to adjust your hygiene efforts to offset these anatomical or treatment factors.
Acid-producing conditions. Diseases like gastro-esophageal reflux disease (GERD) or eating disorders can introduce stomach acid into the mouth that is highly erosive to tooth enamel. It’s imperative for you or a family member to control these conditions through medication, dietary changes, or — in the case of eating disorders — behavioral therapy.
Eating habits. Sugar and other carbohydrates are a ready food source for bacteria. Likewise, acidic foods and beverages (like coffee, tea, and sports or energy drinks) can cause high acid levels for too long. Cut back on eating and drinking these foods and beverages, especially as snacks, to reduce acid levels that could lead to decay.

You know the basics for a healthy mouth: daily oral hygiene and regular dental checkups. But there are other elements unique to you that also factor into your oral care: the mouth and facial structure you inherited from your parents (like a poor bite) and your past history with dental disease. Both of these help define your individual risk factors for potential dental problems.
That’s why you need a treatment strategy personalized to you to achieve the best health possible for your teeth and gums. We create this plan by using a detailed and thorough 4-step process.
Step 1: Identify your unique risk factors. To find your risk factors for dental disease, we carefully assess your history and other areas of oral function and health: the soundness of your supporting bone and gum structures; your teeth’s structural integrity and any effects from decay, enamel erosion or trauma; functional issues like a poor bite, a jaw joint disorder or a grinding habit; and problems with appearance like disproportional gums.
Step 2: Prioritize risk factors and form the treatment plan. Once we’ve identified your individual risk factors, we assess how each could impact you and whether any require immediate treatment. Any current dental disease should be treated immediately to minimize and prevent further damage. Depending on severity, other issues like bite problems or unattractive teeth may be scheduled for later treatment.
Step 3: Execute the treatment plan. With our priorities in place, we then proceed with treating your teeth and gums, the most pressing needs first. Throughout this step, our goal is to bring your oral health to the highest level possible for you.
Step 4: Monitoring and maintaining health. Once we’ve achieved an optimum level of health, we must remain vigilant about keeping it. So we monitor for any emerging problems and perform preventive treatments like clinical cleanings to help maintain that healthy state. This also means regularly repeating our 4-step process to identify and update any new, emerging risks and incorporate them into our treatment strategy.
While this process may seem overly methodical, it can actually result in more efficient and cost-effective treatment. It’s the best way to ensure good health for your teeth and gums throughout your lifetime.
