For over one hundred and fifty years the only real option for filling teeth was using a silver amalgam filling. The fact these contained mercury was concerning to many. To allay those fears, once these fillings are hard, no mercury leaches out or effects us.
In our office today we exclusively use composite resin filling material for restoring most cavities. This is a tooth-colored material that is like a putty and placed then shaped and finally light cured to achieve its hardened form. It’s then smoothed, further shaped and polished. One other option as mentioned on the Cerec page is to scan the prepped tooth and mill a perfectly fitting restoration that is then bonded into place. These tend to last longer though there is an added cost.

Whether you catch a remote control with your tooth or you just want to close off some space between two front teeth composite is often an option.
