The Advantages of Composite Resin Fillings
There is some controversy over the safety of amalgam or silver fillings. The concern focuses on the small amount of mercury that is contained in these restorations. While the ADA has deemed silver fillings safe, some dentists prefer to maintain an amalgam-free practice. These dentists provide tooth-colored, composite resin fillings instead.
What is Composite Resin?
Composite resin is a combination of plastic and powdered glass that replicates the natural look of teeth. Composite resin fillings are tooth-colored, so dentists often use it to make cosmetic improvements to imperfect or damaged teeth.
When treating a cavity, the dentist removes the decay and prepares the tooth to receive the filling. Layering the material and applying a curing light to each layer assures a strong and durable bond. The material is shaped to mimic your previously healthy tooth.
Benefits of Composite Resin over Amalgam
Some benefits of tooth-colored resin fillings are:
- They can be color matched to natural teeth for a uniform smile.
- They require less drilling, so more tooth structure is preserved.
- They harden faster than amalgam.
- They bond to the tooth better, providing superior strength and function.
- They can be repaired if damaged.
- Other Uses for Composite Resin
This material also treats minor dental flaws and can be used as a more economical alternative to porcelain veneers. It is also often used to craft temporary crowns.
