The dental piece by means of a crown, must be recessed, that is to say, carved, sculpted in height of 2.5 to 3mm. And all around.
Depending on the size or shape of the piece, it will be represented between 0.8 mm in the neck of the tooth flush with the gum and 2.2 mm in the body of the piece. With an average 1.5mm. all around. While it is carving, the defective enamel, cavities, spots, filtered fillings etc. are eliminated.
If the cavities are very deep, the gaps will be filled with adhered composite paste.
The carving is done with anesthesia, it is painless. When the anesthesia is gone, the tooth will not have pain at all.
The Crown is held in place by adjustment, friction and cementation, and in some cases also adhesion.
