Clinical crown lengthening is a procedure to lengthen the clinical crown of your tooth. The clinical crown is that part of tooth protruding out from the gumline. There are four reasons your restorative dentist would request Dr. Du to perform clinical crown lengthening. If your dentist is planning a restoration such as a crown and there is insufficient tooth left to hold on a crown, then Dr. Du can crown lengthen the tooth to increase retention. This will also improve the access to the tooth so they can get a better fit for the crown. Also if the crown margin will be less than 2mm from the bone, adjusting will be necessary to prevent chronic inflammation and infection after the new crown is placed. Finally, in cases where gums in the front are covering too much teeth or the gum level is uneven, crown lengthening can improve the esthetics.
