Dr Michael Kan and Dr. Celina Sim uses a number of advanced techniques to replace unsightly amalgam (mercury) fillings with beautiful, unnoticeable white fillings. White fillings are superior because they don’t expand or crack teeth as amalgam does. White fillings (composite materials or porcelain) and CEREC provide the highest quality filling. There has been considerable debate over recent years regarding the safety of mercury fillings, with the majority of dentists now in agreement that the use of white fillings is safer and superior to amalgam.
