CEREC 3D (Chairside Economical Restorations of Esthetic Ceramic) CEREC 3D is a high tech computer imaging technology we use to design, manufacture and install crowns (caps), fillings and veneers.

This software captures the original shape, indentation, height and width of the original tooth and rebuilds the tooth with a ceramic substance – a non-metallic restoration which is bonded to the existing or remaining tooth structure.

What all that means is your repaired tooth looks as natural as it did new without the old dark metallic colouring of previous fillings and crowns.
