Often when insufficient tooth structure remains for a routine filling, a tooth requires a crown (cap) for proper restoration of chewing. First, local anesthetic is gently placed next to the tooth. A core buildup, or base, is placed for strength, and the tooth is prepared by removing a small amount of material on all sides. A temporary crown is made that same day and placed with temporary cement. In 2-3 weeks, a permanent white crown is tried in and cemented. The final crown blends beautifully with your smile and is extremely strong. The crown acts to hold together and protect the remaining tooth underneath.
