Composite vs. Amalgam Fillings
Amalgam fillings were initially developed from a combination of silver shavings, zinc, copper, tin, and mercury as a low-cost alternative to gold restorations. Despite knowledge that mercury is hazardous to humans, amalgams gained popularity as dentistry became more available to the masses. Aside from their potential toxicity, amalgam/mercury fillings pose other risks. Amalgams are temperature-sensitive, expanding and contracting when they come into contact with hot and cold. This can cause hairline fractures and tooth sensitivity. Over time, an amalgam-treated tooth can weaken, often creating a liability to your long-term dental health. Amalgams on biting surfaces can change shape with biting and chewing impact. Tiny cracks in the material or between the filling and natural tooth structure can allow bacterial reinvasion, creating a bigger decay problem than you had at first. Additionally, metal fillings detract from the integrity of your smile and can damage your self-confidence.
Composite fillings are bonded with adhesive to your tooth structure, protecting against decay and strengthening the tooth. This bond can make a composite filling last for seven to ten years. Composite fillings provide long-term bacterial invasion protection, too. Once bonded, a composite filling won't wear down or change shape, despite the incredible forces of biting and chewing. Bacteria and food particles cannot enter the tooth. Because they're tinted to match your natural tooth color, composite fillings will blend seamlessly with your smile.
Porcelain onlays are highly esthetic and return structure, strength, and function to a tooth with extensive decay or damage. Porcelain's translucent quality reflects light similarly to tooth enamel, and because they are shaded to match your tooth, it's difficult to discern from the natural structure. A porcelain onlay will protect your tooth from further damage, and because it requires less reduction of your tooth, it is a conservative option when compared to a crown.
