Composite fillings made of composite resins have a more pleasing and natural tooth-like appearance. Due to the improvements that manufacturers have made in the strength of composite fillings, they now have the potential to be used for all teeth, including molars. They have the added advantage of requiring less tooth preparation and may not weaken the affected tooth as much as amalgam fillings. Since less preparation is required for a composite filling, this usually means that less healthy tooth structure has to be removed to place a composite filling.
More so than amalgam fillings, the success of composite fillings depends on your dentist’s technique. Additionally, composites also require the use of additional equipment and requires up to 50% more time than the amalgam filling procedure. These factors make up the higher costs associated with composite fillings. Often, because of the higher costs, a lot of dental insurance companies do not cover the additional costs associated with composite fillings.
