Composite Resins

For a Clean, Strong Smile

If you have decayed, disfigured, or discolored teeth, we can restore them to an attractive, healthy state by applying a composite resin. A composite resin is a silicon dioxide-filled tooth-colored ceramic mixture that Dr. Carano uses to improve teeth both structurally and cosmetically. Generally, resin placement requires four simple steps: preparation, layering, shaping, and polishing.

Preparing, Layering, & Shaping
Once we've identified the teeth that need to be filled, we simply prepare them by drilling out any decay and cleaning all surfaces with a specialized cleaning agent. Next, Dr. Carano layers the composite onto the teeth, hardening each layer with a special light. When the layering process is finished, Dr. Carano carefully works with the composite, shaping it to fit the tooth and mimic the original dentition. He then polishes it, preventing staining and early wear. Depending on the size of the filling and location of the composite, this placement process may require 10 to 20 minutes longer than what's needed for a traditional silver filling.

Stress, Strain, & Decay
You may not realize it, but each bite you take puts up to 900 pounds of pressure per square inch on the surface of that tooth. Over the years, this kind of pressure can easily cause silver amalgam fillings to change their shape and contour, crack, and possibly create fractures in the tooth as well. Then, decay can creep into the fracture lines and under the loosened filling as well. However, the bond formed between the tooth and a composite resin isn't susceptible to these problems. In fact, it's such a strong bond that the new material actually lends strength to that tooth for the rest of its life, preventing breakage and providing temperature change insulation.

Shapes, Shades & Endurance
There are other important advantages to receiving composite resins as opposed to traditional silver fillings. Dr. Carano is an expert craftsman and as such is able to precisely blend composite shades and shapes so as to match the original teeth nearly perfectly. So your smile is actually improved, rather than compromised. Finally, average- and small-sized composites have been shown to last as long as silver fillings--seven to ten years.

Sensitivity, Stains & Prices
Occasionally, patients experience post-placement sensitivity after receiving their composite(s). However, this will generally pass. Also, the composite shade may darken slightly from tea, coffee or other staining types of foods and beverages. However, if you anticipate this being a problem, Dr. Carano can prevent it by placing a clear plastic coating over the composite. A final consideration may be cost: composites typically run one-and-a-half to two times the price of a traditional silver filling, with insurance covering up to the price of the silver filling and you being responsible for the difference. However, insurance companies will likely increase coverage as composites continue to improve.
