He is highly trained in all aspects of restorative and cosmetic dental work, including crowns, bridges, dentures, implants, and veneers.

Dr. Schwarz began his higher education at Johns Hopkins University in Baltimore, receiving a bachelor of science degree in biomedical engineering and materials science and engineering. While earning his doctor of dental medicine degree from Tufts University School of Dental Medicine in Boston, he served as a clinical teaching assistant. He then completed his dental residency at Columbia University College of Dental Medicine in New York City, where he also earned a master’s degree in prosthodontics and was a clinical instructor.

Cosmetic dentist Simon W. Rosenberg, DMD, of The Center for High Tech Dentistry on the Upper East Side of Manhattan, offers comprehensive care to patients living in and around New York City. 

Dr. Rosenberg received his Doctor of Dental Medicine Medicine (DMD) degree in June 1975 from Tufts University, School of Dental Medicine in Boston, Massachusetts. After graduation, he completed a general practice residency in dentistry at Boston City Hospital (BCH), where he was one of two general dentistry residents, among fifteen oral surgery residents. 

Having obtained a solid foundation in both general dentistry and oral surgery, he was appointed as a staff dentist at Harvard Street Neighborhood Health Center (HSNHC) and as an Assistant Visiting Dentist at Boston City Hospital. At the HSNHC, he practiced general dentistry for two years, dividing his practice between adult, adolescent, and pediatric patients. He was part of the multidisciplinary Primary Care Training Program for pediatric and internal medicine residents and a pilot Adolescent Medicine Clinic at Harvard Street NHC. At BCH, Dr. Rosenberg supervised and taught the general practice residents in the program he had completed. 

Dr. Rosenberg then returned to New York City, to Memorial Sloan-Kettering Cancer Center (MSKCC) to start a two-year postgraduate specialty training residency in general prosthodontics followed by a one-year fellowship in maxillofacial prosthetics. The 1978-1980 residency program emphasized crowns, bridges, partial and complete dentures, and the 1980-1981 fellowship focused on advanced techniques to reconstruct patients after head and neck cancer surgery. During those three years, Dr. Rosenberg also completed the requirements and successfully passed the American Board of Oral Medicine examination and was awarded Diplomate status. Oral medicine achieved recognition as a dental specialty by the American Board of Dental Specialties in 2015. The military, the dental schools, and numerous hospitals have training programs and active research programs in this area. 

Dr. Rosenberg’s interest in this area includes treating the oral complications of head and neck cancer therapy by surgery, radiation, and chemotherapy and the treatment of numerous non-malignant oral conditions that present with mouth sores, ulcers, dryness, etc. In the second year of his residency, Dr. Rosenberg was awarded support from the American Cancer Society. In the third year at MSKCC, he was supported by the Samuel and Hannah Holtzman Trust Fellowship for advanced training in maxillofacial prosthetics. From 1981 to 1983, Dr. Rosenberg was appointed as a “Special Fellow” in the dental service at MSKCC and combined clinical care with teaching and research. His research emphasized the oral complications of chemotherapy, including altered dental development in children treated with chemotherapy for cancer. In 1983, Dr. Rosenberg was appointed to the full-time staff at Memorial Hospital (MSKCC) as an Assistant Attending. He continued on staff at MSKCC until leaving after eleven years to set up a full-time private practice in September 1989. 

In 1985, Dr. Rosenberg passed Phase I, Part 1 of the American Board of Prosthodontics, and became board-eligible in prosthodontics. Dr. Rosenberg’s research support included a junior clinical faculty grant from the American Cancer Society from 1983-1985, a Leukemia Society of America Fellow grant from 1984-1986, two institutional research grants from the ACS, and a three-year clinical investigator grant from the American Cancer Society. 

Over the years, Dr. Rosenberg has published over twenty articles in dental and medical journals, two chapters in recent Dental Clinics of North America, the Care of the Mouth chapter in a cancer textbook (Manual of Oncologic Therapeutics), and co-edited The Clinician’s Guide to the Treatment of Oral Conditions. He has lectured numerous times throughout the United States, Canada, and Colombia, South America. 

Dr. Rosenberg was born in Manhattan in 1950 and raised in Brooklyn. He graduated from Stuyvesant High School and Brooklyn College with a Bachelor of Science in Biochemistry. Currently, he lives with his wife and three children in the New York City area.
