Durability of Dental Fillings
The lifespan of your dental fillings will be directly affected by your oral hygiene. Generally amalgam fillings have a life expectancy of 12 years, whereas composite fillings have a life expectancy of 5-7 years. Technological advances have worked on making the dental composite more durable as the strength of composite resin has increased and can now be used for all tooth restorations, including molars. Composite resin materials also require less preparation time than silver amalgam and may not weaken the tooth as much as metal fillings. Meaning that less healthy tooth structure is removed when placing a composite filling. Yet, amalgam fillings still hold the longer lasting record with regards to dental fillings.
