One of the top concerns in public health today is exposure to the metallic element mercury within the environment. At abnormal levels, mercury can have a toxic effect on our nervous systems and cause other health problems.
These concerns over mercury have also increased attention on one material in dentistry that has included the metal in its makeup for over a century — dental amalgam for filling teeth. Amalgam is a metal alloy that can include, in addition to mercury, silver, tin, and copper. When first mixed dental amalgam is a moldable material used for fillings in prepared teeth. It then hardens into a durable restoration that can withstand biting forces.
While the use of amalgam has declined with the introduction of life-like colored fillings, it's still used for teeth like molars subject to high biting forces. With what we now know about the ill effects of mercury (which can make up to half of an amalgam mixture) is it safe to continue its use?
The American Dental Association has performed extensive research into amalgam safety. They've found that mercury is stabilized by the other metals in the amalgam. This prevents "free" molecules of mercury, the real source of harm to health, from escaping into the blood stream in the form of vapor. Although trace amounts of mercury vapor from the amalgam are released as a person chews, those levels are well below the threshold that could cause harm.
From a patient standpoint, the biggest drawback to dental amalgam isn't safety — it's the appearance of teeth it's used on. Silver fillings aren't considered attractive. And now there are viable filling alternatives that not only look like natural teeth but can withstand biting forces almost as well as amalgam. These materials include composite resins, mixtures of glass or quartz within resin, or glass and resin ionomers. Each of these has advantages and disadvantages depending on how and where they're applied.
After a thorough dental examination, we'll be able to advise you on what filling material will work best to produce the best result. And if we do suggest dental amalgam you can rest assured it will be a safe choice.

We’ve waged war for decades against tooth decay through oral hygiene and the increasing use of fluoride, nature’s “super weapon” against this disease. And yet, tooth decay remains a significant health problem.
One major reason is refined sugar found in many processed foods. In the 1970s researchers raised concerns about the fat content of many processed foods, so manufacturers began removing fat from their products — along with much of the flavor. To compensate, they added sugar. Today, three-quarters of approximately 600,000 food products contain sugar.
This has increased average individual consumption to 90 pounds of sugar annually. The World Health Organization says we should consume no more than 20 pounds annually, or about 6 teaspoons a day. A single can of soda contains 4 teaspoons, two-thirds of the daily allowance.
High sugar consumption is an obvious threat to dental health: decay-causing bacteria thrive on it. But the trend has also been linked to serious health problems like diabetes and heart disease.
Hopefully, changes in public policy will one day modify the addition of sugar in processed foods. In the meantime, you can take action for yourself and your family to create a more healthy relationship with this popular carbohydrate.
Shop wisely. Learn to read and understand food labels: steer clear of those containing sugar or large numbers of ingredients. Become acquainted with sugar’s many other “names” like corn syrup or evaporated cane juice. And maximize your shopping on a store’s outer perimeters where you’ll find fresh fruits, vegetables and dairy products, rather than the middle aisles with “boxed” processed items.
Avoid sugar-added drinks. Limit consumption of sodas, sports drinks, sweet teas or even juice to avoid added sugar. Make water or sugar-free beverages your go-to drinks. It’s much better to eat sugar naturally found in fresh fruits and vegetables, where fiber helps slow it’s absorption in the body, than to drink it.
Exercise. Depending on your condition, physical exertion is good for your overall health. It’s especially beneficial for your body’s ability to metabolize sugar. So with your doctor’s advice, exert your body every day.
It’s important to engender a proper relationship with sugar — a little can go a long way. Putting sugar in its rightful place can help you avoid tooth decay and increase your chances of greater overall health.

Energy drink makers would have you believe their products are a healthy rehydration choice for athletes while also giving them keener focus and renewed vitality. But before adding them to your sports regimen, you should also consider what effect these beverages could have on your teeth.
Energy drinks are similar in ingredients to sports drinks like Gatorade® and PowerAde®, which mostly consist of water, salts, vitamins, sugars and acids. In addition, energy drinks like Red Bull® and Monster Energy® add caffeine to boost energy.
Besides their sugar content, the main threat from a dental health perspective for both of these drinks is their acidity, which can severely erode tooth enamel. The irreplaceable loss of enamel significantly increases your risk of tooth decay and eventually tooth loss.
The threat of enamel erosion is especially pronounced whenever the mouth’s pH level falls below 5.5. The acidity of both sports and energy drinks falls well below this mark. In one experimental study samples of enamel exposed to a number of sports drinks lost an average of 1.5% of mineral content over five days; energy drinks more than doubled that loss at 3.1%.
Given the potential harm these beverages, especially energy drinks, can cause your teeth, you should exercise caution when consuming them. In fact, our best advice is for you to avoid energy drinks altogether, for your overall health as well as your teeth’s sake.
Unless you’re participating in a physically intense sport, water is your best source for hydration after exertion. Â If you do drink sports beverages, try to limit them to meal times when your saliva is most active to neutralize mouth acid. You can also rinse out your mouth with water after drinking to help further reduce mouth acidity.
As an athlete, you’ve trained your body to be at its optimum physical peak. Don’t let energy or sports drinks take the edge off your health, especially your teeth.
