Many people still have silver fillings in their mouths from years past; we can replace them with more aesthetically pleasing composite resins (white fillings). Silver fillings are not particularly pleasing to the eye, and we know that by unavoidable design, silver fillings ultimately result in a weaker tooth structure because they react to heat. As the metal heats and cools, it expands and retracts to create new pockets for bacteria to enter. We use composite filling materials at our office that don’t react to heat like traditional silver fillings and are just as strong as silver fillings.
Composite fillings are actually bonded to your tooth structure instead of being held in place by mechanical retention like silver fillings; with age, the metal of a silver filling expands, contracts, and can split or crack the surrounding tooth structure.
