A crown , commonly known as a “cap”, resembles a natural tooth and covers the defective tooth so that it can regain normal function. The purpose of a crown is to protect and strengthens the tooth structure, thus giving the tooth a longer life.
THERE ARE THREE COMMON TYPES OF CROWNS:
All Porcelain (tooth colored)
Porcelain Fused To Metal
A tooth-colored crown from the inside and outside, that is used frequently for front teeth because it is not strong enough to bear the chewing load, as required by the back teeth. This type can fracture easily.
PORCELAIN FUSED TO METAL
A crown with a metal interior and a porcelain (tooth-colored) exterior, used when strength and natural appearance is required. It is usually recommended in the posterior teeth. The chance of fracture of the crown is minimal, however, the porcelain can chip off revealing the metal underneath.
A crown made entirely of gold. It has the most strength as compared to other types and is recommended for the posterior teeth, since they are not seen as much. Also, can be chosen for people who clench or grind their teeth, as this type of crown has the best durability. It has the least likely chance of fracture.
REASONS FOR CROWNS
Broken or fractured teeth
Tooth undergone root canal treament
