Welcome to N.J. Nicastro Dental PC, where you can find almost every aspect of dentistry for the whole family. N.J. Nicastro Dental PC began as a family practice run by father and son, and we continue to provide that “family” aspect by treating our patients as we would our own loved ones. We have proudly served the Long Island area for over 40 years, and invite you to join our dental family today by contacting our dentists to schedule an appointment.
