Laser crown lengthening is performed around teeth that are broken or have been filled below the gum line and now require treatment with a crown. For us to be able to clean and bond properly to healthy tooth structure, we need to see the tooth clearly and make sure the bonding doesn't interfere with the health of your gum and bone. Previously, this procedure would be performed by a specialist, at a separate visit, and require six to eight weeks of healing before crown preparation. Now, crown lengthening and crown preparation can be performed at the same visit, saving both time and money.
