Restoring the aging dentition.

The aging of the population has put new demands on the range and capabilities of the dentist. Patients are no longer satisfied with the straightforward restoration of their mouths. They are demanding a more youthful appearance as an essential element of therapy. To provide this element, the dentist must have a thorough understanding of the physiology of tooth and facial aging, the treatments available, and the problems and limitations that might be incurred.
