What is a "tooth crown"?
There are a variety of factors that may contribute to the
deterioration of teeth over the course of time. Age, tooth decay,
defective fillings, improper bites and chewing patterns all play a
role in the eventual wearing down and cracking of teeth. Dental
crowns can reverse the effects of time by covering the entire
visible surface of a tooth with enamel and porcelain to both
strengthen the tooth and increase its durability. Crowns also
improve the appearance of worn down and damaged teeth. Your dentist
can tell you which problem areas in your mouth might be helped by
the placement of a crown.
Crowns come in three basic types: gold, ceramic and ceramic veneered
gold crowns. Gold is by far the most durable material and is
normally used in molars where the action from chewing can be most
damaging. However, ceramic and porcelain veneered crowns are very
popular as they can be made to closely resemble natural tooth color.
Advancements in composite resin materials and bonding technology
have also limited the need for metallic crown anchors that hold the
crown in place by the two adjoining teeth. However, in situations
where appearance is not an issue, gold anchors can still provide the
most durable and precise fit.
