Because white fillings are not made of metal, we can blend and mix shades to find the perfect color to match your natural teeth. This means only you and your dentist will know you have fillings. Another pro is that the tooth/composite bond actually supports the remaining tooth structure, deterring breakage and insulating against temperature changes. Medium and small composites can last seven to ten years. That's as long as the tried and true amalgams. Best of all, white fillings allow us to keep more of your natural tooth structure intact than amalgams. We believe in conservative dentistry; the more natural tooth structure you keep, the better teeth you'll likely have in the future.
