A crown, also referred to as a cap, is made to protect the crown, or top, of the tooth. A crown may be a better option when a tooth has a large filling that extends beyond the middle of the tooth. When a tooth is broken down to the gum line, the crown of that tooth may also need to be built-up. A crown build-up uses a material (metal or resin) to heighten the tooth and provide additional strength. A crown can also be an option when there a space between two teeth. Crowns may be made of several types of material, the most common being porcelain or ceramic. Dr. Wright chooses the highest quality porcelain to restore all of patient's teeth to ensure a comfortable fit.
