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.
Did you make any New Year's resolutions this year? For many of us, these pledges reflect a sincere desire for self-improvement—whether it's in terms of our career, our personal lives, or our health. Yet it isn't always possible to keep every promise we make…and while exercising every day and cutting out desserts are worthwhile goals, they may also be very difficult to maintain. Fortunately, when you resolve to improve your oral health, there are some simple things you can do to help keep your smile looking healthy and bright.
Get Into the Oral Hygiene Habit
Got a minute? How about two minutes, twice a day? If so, you have time to brush your teeth properly. According to the American Dental Association (ADA), brushing twice daily with a soft-bristled brush that fits comfortably in your mouth—and replacing that brush every three to four months—is essential to good oral hygiene. The ADA also recommends flossing once a day to clean all the places where your brush can't reach—like in between teeth and under the gum line. Brushing and flossing are the best ways to maintain good oral hygiene at home.
Think Before You Drink
Here's another way to make a big difference in your oral health: Pass up those sugary and acidic drinks, and choose plain, refreshing water instead. We're talking about regular and diet soda, as well as fruit juice and those so-called “sports” or “energy” drinks. The sugar and acid in these drinks can spell disaster for your teeth: Sugar promotes the growth of bacteria that can cause tooth decay, while acid softens the hard enamel covering of your teeth, allowing cavities to get started. Water, on the other hand, satisfies your body's need for hydration without adding calories or harmful ingredients. That what makes it the best drink for your diet—and your oral health.
See Your Dentist Regularly
There are some jobs best left to the pros—like removing the hardened deposits called “tartar” from your teeth, and checking for tooth decay, gum disease and other oral health problems. We'll take care of all that at your routine dental checkup. Plus, you'll get a thorough cleaning and a chance to “brush up” on oral hygiene techniques that can help you keep your mouth healthy throughout the year.

When they’re introducing a new movie, actors often take a moment to pay tribute to the people who helped make it happen — like, you know, their dentists. At least that’s what Charlize Theron did at the premiere of her new spy thriller, Atomic Blonde.
"I just want to take a quick moment to thank my dentists," she told a Los Angeles audience as they waited for the film to roll. "I don’t even know if they’re here, but I just want to say thank you."
Why did the starring actress/producer give a shout-out to her dental team? It seems she trained and fought so hard in the action sequences that she actually cracked two teeth!
“I had severe tooth pain, which I never had in my entire life,” Theron told an interviewer from Variety. At first, she thought it was a cavity — but later, she found out it was more serious: One tooth needed a root canal, and the other had to be extracted and replaced with a dental implant — but first, a bone grafting procedure was needed. “I had to put a donor bone in [the jaw] to heal,” she noted, “and then I had another surgery to put a metal screw in there.”
Although it might sound like the kind of treatment only an action hero would need, bone grafting is now a routine part of many dental implant procedures. The reason is that without a sufficient volume of good-quality bone, implant placement is difficult or impossible. That’s because the screw-like implant must be firmly joined with the jawbone, so it can support the replacement tooth.
Fortunately, dentists have a way to help your body build new bone: A relatively small amount of bone material can be placed in the missing tooth’s socket in a procedure called bone grafting. This may come from your own body or, more likely, it may be processed bone material from a laboratory. The donor material can be from a human, animal or synthetic source, but because of stringent processing techniques, the material is safe for human use. Once it is put in place your body takes over, using the grafted material as a scaffold on which to build new bone cells. If jawbone volume is insufficient for implants, it can often be restored to a viable point in a few months.
Better yet, when grafting material is placed in the tooth socket immediately after extraction, it can keep most of the bone loss from occurring in the first place, enabling an implant to be placed as soon as possible — even before the end of a movie’s shooting schedule.
Will Atomic Blonde prove to be an action-movie classic? Only time will tell. But one thing’s for sure: When Charlize Theron walks down the red carpet, she won’t have to worry about a gap in her smile.
