Crowns are restorations that cover or cap teeth
that are badly damaged or poorly maintained, restoring them to their
natural size, shape and colour. The crown is created to look like
your natural teeth and not only helps appearance but can also save
a tooth that might otherwise be lost and can correct general bite.
Typically porcelain crowns are placed when a significant
amount of tooth structure is lost and when placing a filling would
jeopardize the integrity of the tooth or compromise the aethetics
or strength.

New materials, including the OPC crowns (Optimal
Pressable Ceramic) are extrememly strong and durable crowns make
completely of porcelain and bonded to the tooth. The name for these
is Empress Crowns. These types of crowns are becoming more and more
popular because they are more esthetic, and have NO metal underneath
which can sometimes give a "grey" or "black"
margin "shine-through" at the gumline.
