Frequently Asked Questions
Fillings should be replaced when they crack, leak, fall out, or when new decay forms around them. Amalgam fillings last 10-15 years; composite fillings last 5-10 years on average.
Insurance typically covers replacement fillings when the old filling has failed. Some plans have a waiting period (2+ years) before covering replacement. Elective replacement may not be covered.
Elective replacement of intact amalgam fillings is not medically necessary. However, many patients choose white composite replacements for cosmetic reasons at their own expense.
