Current Dental Restoration Materials
- Amalgams - Known as a Silver filling, amalgams are composed of a mixture of components including mercury. I would not put these in my family's mouth and therefore choose not to use this restorative option in my office.
- Plastics - Plastic fillings look good at first, but do not have enough compressive strength. They expand at a different rate than the tooth which can contribute to temperature sensitivity. They wear away much faster than teeth and can bend when you chew on them and have the potential to leak. Since dentists started using them, the root canal rate has increased.
- Gold - Yellow Gold is an old material. It works well because it is tough and the expansion coefficient is almost the same as the tooth. It is difficult to prepare and it requires careful lab procedures to produce a tight casting. Almost nobody uses it now as it looks yellow. Few people are interested in a yellow tooth.
- Ceramics - Creamis are strong and long lasting. They are bonded directly to your tooth and expand and wear similar to natural teeth.
CEREC creates a ceramic restoration for you that is milled in our office while you watch! There are no dark lines at the gum and the natural colour is unmatched by any lab made material.
