My guest for Episode #281 of the My Favorite Mistake podcast is Dr. Edward Feinberg, a distinguished expert in restorative dentistry who has dedicated over 40 years to advancing dental care. Dr. Feinberg graduated from Tufts University, was trained by his father, Dr. Elliot Feinberg, a pioneer in full coverage restorative dentistry, and practiced in Scarsdale, New York, before moving to Arizona, where he now practices.

He is the Director of ONWARD, an online teaching organization for full coverage restorative dentistry, where he has created over 30 courses and provides a wealth of educational resources.

A nationally recognized lecturer and author, Dr. Feinberg has contributed significantly to dental literature, including his essay collection, "Open Wide: Essays on Challenges in Dentistry to Achieve Excellence." He also serves on editorial boards and councils for various dental associations and has been honored with numerous awards for his contributions to the field.

In this episode, Ed shares insights from over 40 years in the field and discusses his unique approach to saving teeth, which contrasts with the widespread practice of extracting teeth and opting for implants. Dr. Feinberg’s "favorite mistake" involved a crown falling off a colleague’s tooth—a rare but impactful error. Through this experience, he reinforced his belief in trial-based dentistry and using precise techniques to ensure long-lasting dental solutions.

Dr. Feinberg advocates for saving teeth first, using crowns and bridges when appropriate, and stresses that implants should only be used when absolutely necessary. The conversation also touches on the overuse of implants in modern dentistry, the importance of prevention, and learning from mistakes to improve patient care.
