Metal-free fillings : Composite VS Ceramic (Onlays)
Metal-free fillings have largely replaced the old mercury fillings in most part of the world. The last amalgam filling I did was in 2000 ! I don't do them anymore, as their toxicity for the human body and the environment is highlighted through research. Additionally, metal fillings expand and contract with temperature changes, stressing the tooth and causing fractures. As we don't know where the fracture line will occur, it is at the level of prevention to change old amalgam filling if the risk of cracks looks obvious. It is always better, cheaper on the long run to do the dental treatment before the problem occurs.
Which material is best for me?
Modern Composite and ceramic are both fantastic products. They are both here to restore your tooth structure that you lost because of a chip, crack or decay. Dental bonding uses tooth-colored resin (a durable plastic material), applied and hardened with a special light, to "bond" the material to your tooth. They are done in one session, in the mouth directly. Usually, we use them when the cavity isn't too large, if we screen a decay early-on. They last less than ceramic onlays but they are cheaper.
On the other hand, Porcelain fillings are long term solutions. Once the cavity is prepared, an impression is taken and the ceramist, in his laboratory creates a block of ceramic that will replace the missing structure. They bond with your tooth for added strength, match perfectly to your tooth color. Their seal is better, reducing tooth decay
Untreated cavities, leaking old fillings lead to prolonged pain and an increased risk of further tooth decay, which can lead to more involved, costly, and time-consuming dental treatment.
If you do have a cavity then metal-free fillings are for you. They're used to replace old, leaking metal fillings. Additionally, if you currently have metal fillings we can replace them with natural-looking tooth colored fillings. No more unsightly silver or black fillings.
Who is a good candidate for metal-free fillings?
Only your dentist can determine if non-metal fillings are the best option for you. However, generally, anyone with minor tooth decay or anyone who wants to replace an existing metallic filling can be a candidate for tooth-colored fillings. Especially if you want to enhance your smile, you can replace your old amalgam fillings with resin fillings for a healthly new look.
