A Dental Crown is basically a cap that is placed on a tooth, to cover it and recover its shape, size, resistance and improve its appearance, when losing it due to extensive dental caries, fracture of the dental piece or after a root canal.
Dental Crowns, once cemented, completely cover the tooth and remain above the gum line.
A Dental Crown is necessary to protect a weak tooth from a possible fracture. It is also necessary to restore a broken tooth or a tooth that is severely worn, to cover misshapen or badly discolored teeth.
They can also be used to create a replacement for a missing tooth. This is done with a bridge, which covers the space of the missing tooth and requires at least three crowns. Two of those crowns will be placed on the neighbor teeth of the missing one; these healthy teeth are known as Abutment teeth. The two Abutment teeth with crowns become supports for a third crown placed between them; that third crown is known as the pontic. Crowns can be made of different materials: metal, porcelain-covered metal, resin, aesthetic materials such as zirconia or lithium disilicate, or all-ceramic.
HOW DOES THE CROWN FEEL?
The average duration of dental crowns is between 5 and 15 years. The lifespan of a Crown depends on the amount of “wear and tear” it is exposed to, if good oral hygiene practices are followed correctly, and personal mouth-related habits such as bruxism (teeth grinding), chewing ice, nail biting and using teeth to open containers aren’t done.
Although a tooth with a dental crown does not require any special care, it must be remembered that the fact that a tooth has a crown does not mean that it is protected against decay or gum disease. Therefore, good oral hygiene practices should be continued, including brushing teeth at least twice a day, flossing daily, especially around the crown area where the gum meets the tooth.
