Crowns are a type or dental restoration which, when cemented into place, fully cup over the portion of atooth that lies at and above the gum line says Dr Salimi At Estetica. In comparison, fillings are dental restorations that fill in or cover over just a portion of a tooth. Since dental crowns encase the entire visible aspect of a tooth, a dental crown in effect becomes the tooth's new outer surface. A cosmetic dentist might recommend placing a dental crown for a variety of reasons but, in general, most of these reasons will usually fall within one of the following basic categories.
To restore a tooth to its original shape, to strengthen a tooth or to improve the cosmetic appearance of a tooth. Crowns can be made out of porcelain (meaning some sort of dental ceramic), metal (a gold or other metal alloy), or a combination of both. Since a dental crown that has been cemented into place essentially becomes the new outer surface for the tooth, it is easy to imagine how the placement of a crown can restore a tooth to its original shape. It's also easy to see how a dental crown can help to strengthen a tooth by way of being a hard outer shell that encases the tooth structure that lies within it. For both of these reasons, dental crowns are routinely made for teeth that have broken, worn excessively, or else have had large portions destroyed by tooth decay. It is conceivable that a dental filling, as an alternative, could be used as a means to restore a tooth's shape.
