A crown is a tooth-shaped cap that completely encases the tooth’s visible portion.
There are several reasons why someone could need a crown:
To repair a tooth that has been shattered, damaged, or chipped.
To give a weakening tooth more strength
When a tooth has rotted to the point that a filling isn’t possible.
To make teeth more appealing to the eye
To fix a tooth that had a big filling that was potentially failing.
To strengthen and seal a tooth after a root canal
Different types of dental crowns
The following are the most frequent materials used in tooth caps:
Ceramic: Porcelain or zirconia that has been tinted to match the surrounding
teeth.
Metal alloys: These include gold, platinum, palladium, and non-precious metals;
they can be “white” (silver-colored) or “yellow” (yellow-colored) (gold-colored).
Some people choose gold crowns because they prefer the way gold teeth look
(read more about other gold dental swag here).
PFM (porcelain-fused-to-metal): a hybrid of the two, with ceramic fused to an
inner metal crown.
Resin/composite crowns are less expensive and last less time than other types;
they can be used as temporary crowns while you wait for a permanent crown.
