Used where teeth are heavily filled or badly broken
down - unlike veneers, crowns cover all surfaces of
the tooth. This treatment involves shaping of the original
tooth so that a crown will fit over it, the taking of
impressions and making the crown at the laboratory.
Crowns can be made from porcelain bonded to white gold,
totally out of porcelain or the newer zirconium based
crowns. These new all ceramic crowns are equally as
strong as the metal based crowns and having no metal
in them they are much more natural looking and do not
leave a black line at the gum margin as seen in so many
conventional metal based crowns.
