Your dentist may recommend having a crown(s) in order to protect damaged cracked, or worn teeth. A dental crown is a tooth shaped cap, placed over a tooth to improve its appearance, and restore its shape, size and strength. The dentist will shape the tooth and take an impression which will be sent to a dental technician. The technician will construct a custom made crown which will be permanently cemented into place by the dentist at a subsequent appointment.In the interim phase a temporary crown will be constructed and fitted onto the tooth by the dentist. Crowns can be made from various types of material including an all porcelain, all metal or a porcelain and metal mix. Your dentist will discuss with you the most suitable option for your needs.
