Crowns for the teeth can be of various kinds depending on their use and make:
Depending on the material of the crown, they are of the following types:
The most realistic-looking tooth replacements are the translucent all-ceramic crowns. If your front tooth is broken or cracked, or if it is severely damaged and cannot be fixed with a veneer, an all-ceramic crown may be your best option for restoration.
Dental technology has advanced to the point where it can now offer materials like zirconia, E-max, and many more. Zirconia crowns are three times more durable than regular porcelain ones. It allows for the blending and matching of hues, translucency, and tones for a realistic appearance.
These are the conventional crowns used by dentists for the back teeth. They are made of stainless steel and are very durable. A few reports suggest side-effects such as corrosion and leaching of metal crowns, but conclusive results are rare.
These are crowns made of acrylic resin. They are usually fixed for an interim period, hence they are not durable. However, you can eat regular food with them.
PFM, or Porcelain Fused to Metal, crowns combine the benefits of both the standard dental materials: the durability of metal and the esthetics of porcelain. They are cost-effective and also rehabilitate your smile.
