The main goal of a crown is to be able to ensure that the healthy tooth structure that’s left after damage, decay, or an infection is preserved and protected from further problems. The best way to protect the tooth is to encapsulate it with a dental crown, which will cover the entire visible portion of the tooth all the way to the gum line where it is then cemented to the tooth. A crown can make you feel more confident smiling, biting and chewing.
