Cavities form when plaque, which is made-up of the bacteria in your mouth, develops into acids that stick to the enamel of your tooth and break down the surface.
Plaque can get stuck in the pits and grooves of the biting surfaces of teeth and on the smooth areas like the front and backs of teeth (or even in between the teeth). Usually plaque gets brushed away with your toothbrush, but when you forget to brush for several days, plaque can spread and result in a sensitivity within your tooth or actually reach the root and cause you pain.

Dentists like Dr. Davidson repair cavities by sealing the hole from the plaque with tooth-colored restorations. The older type of filling material, a metal alloy contains mercury and is not used often, but some patients still have these types of fillings in their mouths. After the decayed area is removed with a dental drill, the filling material is added to prevent the decay from spreading further into your tooth.
The older type, silver fillings, have been used for more than a century, but they are actually not made-up of pure silver. These dental amalgams are actually an alloy of mercury, silver, tin, and copper. The mercury combines with the other metals to make the compound strong and stable.
The advantages of silver fillings are that they are strong and inexpensive, but the disadvantages are quite numerous:
Fortunately, silver fillings can safely be replaced with tooth-colored restorations.
There are many advantages to tooth-colored restorations also called composite resins and onlays.
These tooth-colored restorations or resin onlays are not only aesthetically pleasing, but they are bonded to the teeth creating a tight, superior fit to the natural tooth. Such restorations can be used in instances where much of the tooth structure has been lost.
Since the resin used in tooth-colored restorations contain fluoride this also helps prevent decay. The resin wears like a natural tooth and does not require placement at the gum line, which is healthier for your gums!
The result is a beautiful smile!
You can have your silver fillings replaced with tooth-colored restorations (onlays). This process requires two appointments.
