Crowns are a type of dental restoration permanently cemented. Crowns are used to rebuild broken or decayed teeth, to strengthen teeth, and as a means by which to enhance the cosmetic appearance of teeth. Crowns can be made out of porcelain/ceramic, gold alloy, or a combination of both. Dental crowns are often referred to as “dental caps”.
Cracked tooth – When a tooth is cracked, a filling will not seal the crack. A crown has to be placed over the tooth to hold it and the crack together. If a crown is not placed on the tooth, the tooth will become sensitive to chewing pressure, or will eventually break. It is important to crown a cracked tooth before it breaks, because in some cases a broken tooth cannot be crowned and must be extracted.
