At our Glendale and Phoenix cosmetic dental office, we discontinued routine placement of silver-mercury fillings due to the concern about their mercury content, the natural appearance of white (composite fillings) and their ability to bond to natural tooth structure. The concern about the safety of the white fillings is the bisphenol A (BPA) that is a part of most plastics. Research has shown the BPA can leach out of plastics and create health risks. Dental composites contain BisGMA. This ether group is very stable and not susceptible to decomposition by conditions found in the oral cavity. Bis GMA does not break down into BPA.

Our smile gallery shows a small sample of the hundreds of patients we have helped have the smile and self confidence of their dreams.
