Bonding, white fillings, porcelain veneers, onlays and crowns require attention to detail. Research shows that sensitivity and bond failure often results from incomplete polymerization of the material. Polymerization is initiated by a high intensity light which if not maintained or updated will underperform. This is a common problem. We monitor the intensity using an electronic device on a weekly basis. In addition we just invested in the highest rated light emitting diode curing light on the market. This is not something most people would ever think of, but it is important.
