A crown is necessary when a tooth is damaged due to decay (cavities) or trauma and cannot be repaired with a filling. Crowns are made from different materials, but porcelain crowns are the most popular because they are the most natural looking. A crown, sometimes called a cap, is used to build up tooth structure so that it can function as a natural tooth. At Calm Dental we artistically craft every crown, so that it will blend in flawlessly with the rest of your teeth. As part of a smile makeover, you might also want to replace your old metal crowns with porcelain crowns. This will restore the original beauty and strength to your smile.
