How do dental crowns strengthen teeth?
The strengthening capability of dental crowns is related to the fact that they cup over and encase the tooth on which they are placed, thus serving as a splint which binds the tooth together. Dental crowns are a very important means by which a dentist can strengthen a tooth. In contrast, dental fillings, especially large ones, often have a weakening effect on the teeth in which they are placed. Dental fillings rely on a tooth’s remaining structure to hold and support them. Fillings, in general, don’t strengthen a tooth and don’t protect a tooth from the forces generated by biting and chewing.
