Michael k. Deenihan D.D.S. (Ret.)

Dentist Montclair NJ

Michael k. Deenihan Dr. Deenihan’s practice was dedicated to providing all phases of family and cosmetic dentistry while incorporating the latest in dental materials, equipment and techniques. Dr. Deenihan was selected by his peers as a “Top Dentist” in Montclair for the past ten years. Dr. Deenihan enjoyed transitioning his practice to Dr. Davidson in the past year. Dr. Deenihan found that Dr. Davidson shares his same treatment philopsophy, desire for excellence, and overall welcoming and warm personality. Leaving his practice to Dr. Davidson who is also a “Top Dentist” in Montclair was a no brainer and an easy transition. 

Dr. Deenihan received his dental degree in 1980 from the University of Maryland. After completing his hospital residency at the Presidio in San Francisco, Dr. Deenihan acquired the practice of Drs. Paul, Johnston and Carroll in Montclair in 1982. Established in 1928, it is the oldest continuous dental practice in Montclair, having served up to five generations of Montclair families. Dr. Deenihan has continued to receive advanced training in cosmetic, restorative and endodontic therapy.
