When cavities, fractures or trauma damage teeth a filling may not be able to fix the situation. When a majority of the tooth is gone, something more solid and whole is needed to fix the problem. That is when crowns (caps) or onlays (a restoration that replaces a lot of tooth structure) are used. With CEREC 3D we can make some crowns and onlays in the office while you wait. That means no second appointment and no temporary. They are natural looking and as hard as your natural teeth. CEREC restorations can not be used in all situations and we will always chose what treatment is in your best interest.
