RESTORATIONS
There are any number of ways in which your dentist can restore your teeth. Whether teeth are damaged, diseased, or decayed, a method exists to return the teeth to a normal appearance and function. These techniques range from the simple to the very complex, but are all designed to protect, repair, or replace your teeth.
Fillings
The most common form of restoration is the filling. The procedure itself is very simple. A local anesthetic is used to completely numb the area of the tooth to be filled. After the area has been anesthetized, any decay is removed and the tooth interior is shaped to accept the filling. The filling material is then pressed into place and shaped to create a natural surface contour. The filling material is then smoothed and polished. The materials used to fill teeth are silver amalgam or resin composites. Silver amalgam fillings are not as natural-looking as tooth-colored restorations, but they have a long history of strength and durability. Resin composite fillings are much more natural-looking, but can be somewhat more expensive than silver amalgam fillings.
Resin Composite Restorations
The procedure for a composite restoration is essentially the same as for a traditional amalgam filling. After the tooth has been cleared of decay and properly shaped, the interior is then etched with a mild acid solution to aid bonding to the composite filling material. In most cases, the tooth is banded, and the composite is applied in successive layers. Each layer in turn is hardened with a high-intensity light. When the cavity is completely filled, the surface of the restoration is shaped to match the contours of the original enamel. A composite restoration is extremely durable, and perhaps the most aesthetically satisfying option. Fillings in particular are subjected to tremendous forces during biting and chewing, and are in constant use. Over time they may simply wear out, and may have to be replaced. |
