Why Do I Need Crown Lengthening?

Periodontal procedures are available to lay the groundwork for restorative and cosmetic dentistry and/or to improve the esthetics of your gum line. Do you feel your teeth look too short and your smile is too gummy or your gums cover too much of some teeth while leaving the others the right length? Your teeth may actually be the proper lengths, but they're covered with too much gum tissue. To correct this, your periodontist performs crown lengthening. This can be done to one tooth, to even your gum line, or to several teeth to expose a natural, broad smile.

Your dentist or periodontist may also recommend crown lengthening to make a restorative or 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 bridge.

What are the benefits of crown lengthening?

Whether you have crown lengthening to improve function or esthetics, patients often receive the benefits of both: a beautiful new smile and improved periodontal health - your keys to smiling, eating and speaking with comfort and confidence.
