Advantages of Composites
The benefits of composite fillings include:
Unlike metal or amalgam (silver) fillings, composite fillings look like a natural tooth. Dr. Marra can blend the color to match your other teeth. This makes composites ideal for front teeth, where an amalgam filling would be unattractive. Composites can be shaped to resemble a real tooth.
Composite fillings bond with the tooth, offering support to a tooth weakened by decay. In addition, less tooth needs to be removed to prepare for the composite filling as compared to an amalgam filling. Tooth material should be preserved whenever possible as it may be useful in future restorations.
Amalgam fillings are more likely to expand and contract when exposed to hot and cold foods, leading to cracks. The insulating qualities of composite fillings offer more protection from destructive temperature swings.
Composite fillings are durable and resistant to fracture in small- to mid-size fillings. When composite fillings were first introduced, they weren’t strong enough for back teeth where grinding and chewing exerts more force. However, in the past decade, the durability of composites has improved.
In addition to filling cavities, the composite material can repair chipped, broken, or worn teeth.
