Often a person may have a "gummy" smile where the teeth appear to be short. The teeth may actually be the correct length, but are covered by too much gum tissue. This may be corrected by Dr. Hyatt doing crown lengthening procedures that reshape both the gum and the underlying bone tissue. This establishes the proper proportions of the tooth's width to height. This greatly improves appearance. Crown lengthening may also be needed when a tooth is broken or decayed below the gum level. This area must be exposed so the tooth can accept a filing or a crown.
