Marble tiles and rich gold accents sparkle through the Astor Estate building's ornate lobby as guests journey to Manhattan Dental Spa's office tucked away on the 22nd floor. The spa's friendly staff guides patients through graceful hallway arches and into semi-private rooms outfitted with advanced medical equipment and adjustable flat screen TVs. Dr. Joseph Greer D.D.S. and Dr. Mitchell Charnas, D.M.D., along with an experience staff that includes a periodontist, endodontist, and an oral surgeon, revamp clients' choppers with general cleanings, implants, and Invisalign. Along with cosmetic services, the staff also performs beauty injections, gently injecting dermal fillers such as Botox and Restylane into fine lines etched around the mouth, nose, or brow, immobilizing wrinkle-making face elves for up to four months.
