-
Replacement crowns look attractive and natural, and match
the adjacent teeth.
-
The visible part of the tooth
above the gum line is called "the crown".
-
If
the natural crown is unattractive, decayed or damaged, it
can be
aesthetically
repaired with a "replacement
crown".
-
The dentist pares down the original tooth, takes an impression
of it, and sends it to a dental technician.
-
The technician uses the impression to make a cast of the
prepared tooth.
-
A plaster
cast is an exact copy of the prepared tooth and the adjoining
teeth.
-
A replacement
crown is made to fit the cast, and is sent back to the
dentist.
-
The dentist then
cements the replacement crown onto the prepared tooth.
-
Replacement
crowns are usually made of porcelain, or porcelain fused to
metal.
-
A temporary
plastic replacement crown will cover and protect the pared
down tooth until the permanent crown is ready to be cemented
onto it.
