Turn Those Ugly Metal Fillings Beautiful White
Did you ever wish your teeth would look like they used to, before they were filled with all of those silver-mercury fillings? Many patients have found that wish a reality, with a magic wand waved in one visit changing those dull, ugly unnatural looking metal fillings to flawless, white teeth. And the magical filling material that makes it all happen is composite resin.
Composites are some of the strongest materials in use today. These versatile materials are used in the aircraft industry to fabricate the bodies of ultra-fast jet fighters, by NASA in the design components for space vehicles and satellites as well as by dentistry for tooth filling material. When used for teeth, composite is a tooth-colored mixture of specialized polymer resins filled with microscopic ceramic particles. Composites are used to fill cavities, and for cosmetic improvements of the smile by changing the color of the teeth or reshaping disfigured teeth.
How is a composite placed?
Following the preparation of the tooth, we place the composite in layers, much as an artist or sculptor creates a perfect work of art. Once placed, a specialized blue light is used to harden each composite layer. When the process is finished, the composite goes through a final shaping and polishing to prevent staining and wear.
How long does it take to place a composite?
For a skilled dentist, it takes the same amount of time to place a composite filling as a silver-mercury filling. Placement time depends on the size and location of the cavity. Placement time also depends on the cosmetic needs of the particular tooth.
What are the advantages of composites?
Strength and esthetics are the main advantages. These materials are incredibly strong and have the ability to duplicate the strength of tooth structure. Because composites bond to the tooth to support the remaining tooth structure, it helps to prevent breakage and insulate the tooth from excessive temperature changes. In addition, we can blend shades to create a color identical to that of the actual tooth.
