Dental amalgam—also known as “silver fillings”—has been used for nearly a hundred years to treat cavities. There are several reasons why this mixture of metals has been the go-to material among dentists: Malleable when first applied, dental amalgam sets up into a durable dental filling that can take years of biting forces. What’s more, it’s stable and compatible with living tissue.
But there’s been growing concern in recent years about the safety of dental amalgam, with even some wondering if they should have existing fillings replaced. The reason: liquid mercury.
Mercury makes up a good portion of dental amalgam’s base mixture, to which other metals like silver, tin or copper are added to it in powder form. This forms a putty that can be easily worked into a prepared cavity. And despite the heightened awareness of the metal’s toxicity to humans, it’s still used in dental amalgam.
The reason why is that there are various forms of mercury and not all are toxic. The form making headlines is known as methylmercury, a compound created when mercury from the environment fuses with organic molecules. The compound builds up in the living tissues of animals, particularly large ocean fish, which have accumulated high concentrations passed up through their food chain.
That’s not what’s used in dental amalgam. Dentists instead use a non-toxic, elemental form of mercury that when set up becomes locked within the amalgam and cannot leach out. Based on various studies, treating cavities with it poses no health risks to humans.
This also means there’s no medical reason for having an existing silver fillings removed. Doing so, though, could cause more harm than good because it could further weaken the remaining tooth structure.
The most viable reason for not getting a dental amalgam filling is cosmetic: The metallic appearance of amalgam could detract from your smile. There are newer, more life-like filling options available. Your dentist, though, may still recommend dental amalgam for its strength and compatibility, especially for back teeth. It’s entirely safe to accept this recommendation.
Howie Mandel, one of America’s premier television personalities, rarely takes it easy. Whether performing a standup comedy gig or shooting episodes of America’s Got Talent or Deal or No Deal, Mandel gives it all he’s got. And that intense drive isn’t reserved only for his career pursuits–he also brings his A-game to boosting his dental health.
Mandel is up front about his various dental issues, including multiple root canal treatments and the crowns on his two damaged front teeth. But he’s most jazzed about keeping his teeth clean (yep, he brushes and flosses daily) and visiting his dentist regularly for cleanings and checkups.
To say Howie Mandel is keen on taking care of his teeth and gums is an understatement. And you can be, too: Just five minutes a day could keep your smile healthy and attractive for a lifetime.
You’ll be using that time—less than one percent of your 1,440 daily minutes—brushing and flossing to remove dental plaque buildup. This sticky, bacterial film is the main cause of tooth decay and gum disease. Daily hygiene drastically reduces your risk for these tooth-damaging diseases.
But just because these tasks don’t take long, that’s not saying it’s a quick once-over for your teeth: You want to be as thorough as possible. Any leftover plaque can interact with saliva and become a calcified form known as calculus (tartar). Calculus triggers infection just as much as softer plaque—and you can’t dislodge it with brushing and flossing.
When you brush, then, be sure to go over all tooth areas, including biting surfaces and the gum line. A thorough brushing should take about two minutes. And don’t forget to floss! Your toothbrush can’t adequately reach areas between teeth, but flossing can. If you find regular flossing too difficult, try using a floss threader. If that is still problematic, an oral irrigator is a device that loosens and flushes away plaque with a pressurized water stream.
To fully close the gate against plaque, see us at least every six months. Even with the most diligent efforts, you might still miss some plaque and calculus. We can remove those lingering deposits, as well as let you know how well you’re succeeding with your daily hygiene habit.
Few people could keep up with Howie Mandel and his whirlwind career schedule, but you can certainly emulate his commitment to everyday dental care—and your teeth and gums will be the healthier for it.

One of the most common and anguish-filled birth defects is a cleft lip or palate (roof of the mouth). Not only do clefts disrupt the normality of a child’s facial appearance, they can also lead to problems with chewing, speech and the long-term health of teeth and gums.
A cleft is a tissue gap that occurs during fetal development, usually in the first trimester, in which parts of the baby’s face fail to unite. Why this occurs is not fully understood, but vitamin imbalances in the mother, exposure to radiation or other toxic environments, or infections are all believed to play a role.
Facial clefts are classified as either incomplete, in which there is some but not full tissue fusion, or complete, with no fusion at all. A cleft can be unilateral, affecting only one side of the face, or bi-lateral, affecting both sides. During infancy a cleft can adversely affect a child’s ability to nurse, and it sometimes disrupts breathing. As the child grows, speech patterns may be severely disrupted and their teeth and bite may not develop properly.
Fortunately, there have been dramatic advances in cleft repair over the past sixty years. It’s actually a process that can span a child’s entire developmental years and involve the expertise of a number of surgical and dental specialists. For a cleft lip, the initial surgical repair to realign and join the separated tissues usually occurs around three to six months of age; repair of a cleft palate (where the gap extends into the roof of the mouth) between 6 and 12 months.
Subsequent procedures may be needed in later years to refine earlier results and to accommodate the mouth’s continuing growth. At some point the treatment focus shifts to cosmetic enhancement (which can include implants, crown or bridgework) and periodontal health, to ensure gum tissues that support teeth and gums aren’t compromised by the effects of the cleft or its treatment.
At the end of this long process, something of a miracle may seem to occur: a young person’s once disfigured mouth transforms into a beautiful smile. It’s a chance for them to gain a normal life — and a new lease on physical, emotional and oral health.
