What is Crown Lengthening?
Crown lengthening is sometimes necessary in order to improve restorative and cosmetic dentistry outcomes. There are two types: functional and esthetic.
Functional Crown lengthening
Functional Crown lengthening may also be recommended by your dentist to make a restorative or cosmetic dental procedure possible. If you wish to save a tooth that is badly decayed, broken below the gum line, or has insufficient tooth structure for a restoration, this procedure is required to keep your tooth healthy. There has to be at least 2 mm of tissue space between your bone levels and the bottom of a filling or crown. Not having this amount of space can lead to inflammation and tooth loss. This lack of space between the jawbone and the crown or restoration margin is known as biologic width violation. Crown lengthening is completed by rolling back the gum tissue, removing some bone around the affected tooth with a surgical drill and then replacing the gum tissue at a lower level to make the tooth look longer or lengthened. The ultimate goal of this procedure is to increase the length of the tooth to allow an adequate restoration on the tooth thereby saving the tooth.
Frequently Asked Questions
During the dental crown lengthening procedure, excess gum and bone tissue is reshaped to expose more of the natural tooth. This can be done to one tooth, to even your gum line, or to several teeth to expose a natural, broad smile.
Crown lengthening is necessary when a dentist identifies decay in the tooth they cannot easily access. This decay is usually hidden deep beneath the gums, and no matter what methods they use, they cannot properly access the decay without performing a crown lengthening procedure.
If you are having a crown lengthening, you will be put under local anesthesia so that you will not feel any pain during the procedure.
After crown-lengthening surgery, you'll generally need to wait 4 to 6 weeks for your gums to settle into their new position before getting your final crown. If it's in an esthetic area, you may wait even longer because the gums may continue to shrink slightly for up to 12 weeks.
