Dr. Chuck Le, the dentist of 7 Day Dental in Orange County, talks about tooth colored fillings (or white fillings). By contrast to silver amalgam fillings, white fillings expand and contract less so they don’t put stress on the tooth that can cause cracks. Also tooth colored fillings are bonded onto the tooth and make them stronger. Silver amalgam fillings are the old traditional way to fix tooth decay. Besides some negative effects, they have a tendency to expand and contract when exposed to heat and cold and that can cause a tooth to crack.
