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.

As a member of the best-selling pop group Spice Girls, Mel C (AKA Sporty Spice) enjoyed her share of musical superstardom. At the band’s peak in the Nineties, the young singer’s signature look featured baggy sweatpants, an assortment of tattoos, a nose stud and a gold-capped incisor, front and center in her mouth. Today, Melanie Chisholm is still singing — but now she’s a mom, an amateur triathlete… and that gold tooth is just a memory. Not only that, her smile looks more evenly spaced and whiter than it did when she was referred to as the “tomboy” of the group.
What happened? In our view, it all boils down to changing tastes — plus a little bit of help from dental professionals. As the “wannabe” singer proves, there’s no single standard when it comes to making your teeth look their best. Your own look is unique to you — and your smile can reflect that individuality.
For example, crowns (caps) are substantial coverings that may be placed on teeth when they are being restored. They are available in three types: gold, all-porcelain, or porcelain-fused-to-metal. The latter two are tooth-colored, while the gold is — well, shiny like gold bling. Which one is right for you? In many cases, it’s your choice.
Likewise, dental veneers — wafer-thin shells that can correct cosmetic issues by covering the surface of your teeth — can be made in a variety of shades. Their hues may range from natural ivory to Hollywood white, and everything in between. What’s the best color for you? Only you can say.
Some people opt for a “smile makeover” that uses small irregularities in the spacing and color of teeth to create a more “natural” look. Other folks want a perfectly even, brilliant white smile that dazzles the eye. Still others are looking to match or restore the smile they once had — perhaps even re-creating a signature gap between the teeth. As long as there are no other dental issues involved, the choice is yours.
So if you’re unhappy with your smile — or if you feel it doesn’t reflect the person you “wannabe” — why not talk to us about a smile makeover? Just call our office to schedule a consultation.
