Composite Resins: Strengthen Your Smile
If you’re embarrassed about your smile because of decay or dark fillings in your teeth, you may be a good candidate for composite resins. A silicon dioxide-filled, tooth-colored plastic mixture, composite resins can restore teeth to an attractive, healthy state. Composite resins represent several advantages over traditional silver, or amalgam, fillings.
Because composite resins are not made of metal, we can blend and mix shades to find the perfect color to match your natural teeth. Also, composite does not cause expansion and contraction of the tooth which can lead to root canal—this was common with old amalgam (silver) fillings. The shade matching with composite fillings means only you and your dentist will know you have fillings.
Another pro is that the tooth/composite bond actually supports the remaining tooth structure, deterring breakage and insulating against temperature changes. Medium and small composites can last ten to fifteen years – that’s as long as amalgams. Best of all, composite resins allow us to keep more of your natural tooth structure intact than amalgams.
We believe in conservative dentistry – the more natural tooth structure you keep, the better teeth you’ll likely have in the future.
Some patients may experience mild and temporary post-placement sensitivity from composite resin fillings. Dr. Glerum places special densensitizing medication under the fillings to avoid this.
The only caution we usually mention is that coffee, tea, and other staining foods and beverages may discolor your composites over time. Dr. Glerum places a clear plastic sealant over the filling to maintain its beautiful white shade longer.
