Crowns or "caps" are oral health restorations that are custom fabricated, bio-compatible reinforcement that fits right over top of the tooth or teeth. Often, crowns may be required to cover broken fillings, chipped, fractured, or sensitive teeth. Crowns can also be used cosmetically to improve the appearance of discolored, malpositioned, or malformed teeth.
Dental crowns are made from durable tooth coloured porcelain ceramic products that are specifically designed to enhance your overall smile or to blend in with your own natural teeth. There are certain indications that might suggest that you require a crown are for a large filling that now is larger than the actual tooth. The tooth structure has become too weak to support the filling. Other reasons you may need a crown is that there is extensive damage caused by tooth decay, discolorations and compromised esthetics, and tooth fractures. Furthermore, after a root canal, teeth can become more brittle and more likely to break or fracture. A crown could be used to protect the tooth. In addition, missing teeth can be replaced with a dental bridge, with the neighboring teeth being used as support for the replacement teeth.
As well as providing the necessary strength and protection, crowns can also improve the aesthetic appeal of your teeth.
