Composite “fillings” are a mixture of glass or quartz filler material combined with resin; the result is a tooth-colored filling. Composite fillings are highly durable and help the tooth structure resist fracture. They are most effective when used in small to mid-sized restoration, one that will need to withstand moderate chewing pressure. One major advantage of composite fillings is typically less tooth structure needs to be removed. Removing less tooth structure may result in a smaller filling. Composite fillings are “bonded” or adhered to the tooth cavity helping the restoration strengthen the tooth structure.
