Over a period of time, the jaw bone associated with missing teeth atrophies or is reabsorbed. This often leaves a condition in which there is poor quality and quantity of bone suitable for placement of dental implants. In these situations, most patients are not candidates for placement of dental implants.
Crown lengthening is usually performed to improve the health of the bone and gum tissue, prepare the tooth for a restoration, or correct a “gummy smile”. Crown lengthening is often required when your tooth needs a new crown or other restoration.
