Crown Lengthening for a Restoration

Your dentist or periodontist may also recommend a dental crown lengthening procedure to make a restorative or a cosmetic dental procedure possible. Perhaps your tooth is decayed, broken below the gum line, or has insufficient tooth structure for a restoration such as a crown or a bridge. Crown lengthening adjusts the gum and bone level to expose more of the tooth so it can be restored.

Occasionally your dentist will send the periodontist a clear plastic guide that will fit over your teeth to show the periodontist the exact location where the gum tissue should be trimmed. Your dentist will make this guide by taking molds of your teeth and gums.

Questions to ask if you are considering a crown lengthening procedure for a restoration:

  • What can be done if the root is exposed after treatment?
  • How long will I need to wait before my dentist can place the final restoration?
  • What happens if the decay is too deep under the gum to restore the tooth?
