Once upon a time, when you had a cavity, you went to the dentist and came back with a tooth filled with metal: the common silver (or, technically speaking, “dental amalgam”) filling. But today — driven by dental researchers' quest to find a better filling material, and by the desire of many people to avoid a mouth full of dull gray metal — there are other choices.
In recent years, metal-free, tooth-colored fillings have evolved into a well-established treatment method that's finding increasing use — not just in the front of the mouth, where it's most visible, but in the back too. To help understand the benefits of these new materials, let's start by looking at the structure of the tooth.
We usually think of teeth as being hard, sturdy and durable. But did you know that their crowns, or top surfaces above the gums, actually flex under the force of the bite? Understanding the composition and behavior of teeth has led researchers to develop newer and better materials for restoration. These include improved dental porcelains and composite resins which more closely mimic the natural teeth in both function and form: That is, they're strong and good-looking too.
What's more, using these materials for fillings may mean that you can get the same result with a more conservative treatment. How? It all comes down to tooth structure. To secure a traditional amalgam (silver) filling, a tooth often had to be shaped with “undercuts,” which helped hold the material in place. This meant the removal of a greater amount of tooth structure, potentially leading to chipping or cracking of the tooth down the road.
Enter composite resins. Bonding these materials to the underlying tooth doesn't require undercutting, so less of the healthy tooth is removed. That makes for a more robust tooth structure, with potentially greater longevity. Combine that advantage with the aesthetic appeal of a restoration that's hard to tell apart from natural teeth, and you've got a winning combination.
There are different options available for restorations with tooth-colored materials. These range from quick, single-visit fillings for small cavities, to the fabrication of more extensive replicas of the tooth for complicated restorations. Exactly which treatment is needed will depend on an individual's particular dental issue and the kind of results they desire. Whatever the case may be, we can listen to your concerns, answer your questions, and offer the best advice regarding your treatment options.

Fans of the classic bumbling-buddies comic film “Dumb and Dumber” will surely remember the chipped front tooth that Jim Carrey sported as simpleminded former limo driver Lloyd Christmas. Carrey reportedly came up with the idea for this look when considering ways to make his character appear more “deranged.” He didn't need help from the make-up department, however… He simply had his dentist remove the dental bonding material on his left front tooth to reveal the chip he sustained in grade school!
Creating a Bond
A dental cosmetic bonding involves application of a composite filling material that our office can color and shape to match the original tooth. Bonding material can be used to replace the lost portion of tooth or to seamlessly reattach the lost portion if it has been preserved and is otherwise undamaged. Little to no removal of existing tooth surface is needed. This is the quickest and lowest-cost option to repair a chip.
When a relatively large portion of the tooth is missing, a crown is often the better choice. It fully encases the visible portion of the remaining tooth above the gum line and is shaped and sized to match the original. It can be made of tooth-colored porcelain fused to metal crowns or all-ceramic (optimal for highly visible areas). A small amount of the existing tooth surface will be removed to allow the crown to fit over it.
A veneer can be used to hide smaller areas of missing tooth. This is a thin, custom-made shell placed on the front of the tooth to give it a new “face.” Some removal of existing tooth surface also may be necessary to fit a veneer.
A chipped tooth makes an impression, but generally not a flattering one. Nearly 20 years after “Dumb and Dumber” hit the theaters, the only thing Jim Carrey had to do recently to hint at a sequel for his nitwitted character was tweet a photo of that goofy grin!
