Dr. Tay has long been a vocal advocate for the establishment of a Dental Specialist Register and was the first in Singapore to officially limit his dental practice to the specialty of prosthodontics. He is widely known in the prosthodontic world for his expertise in full-mouth occlusal rehabilitation using the N.U.S. treatment philosophy which he originated in 1992. He has built a strong clinical reputation for the diagnosis and successful management of patients with Temporomandibular Disorders(TMD), chronic orofacial pain and headache. Locally, he is known to his medical colleagues as the pioneer in Dental Sleep Medicine and Oral Appliance Therapy for Sleep-Disordered Breathing (SDB) which he manages in close collaboration with a team of sleep professionals. Dr. Tay has been an Academic Advisor to the International Sleep Academy since its inception.
He has published widely in scientific journals, served on their editorial boards, contributed to prosthodontic textbooks and given many presentations and courses on Occlusion, Prosthodontics, Temporomandibular Disorders (TMD) and Sleep Dentistry both locally and overseas. He holds membership in several organizations including the International College of Prosthodontists, American Academy of Dental Sleep Medicine, Academy of Osseointegration (USA), American Equilibration Society, ASEAN Sleep Surgical Society and is a life member of the Pain Association of Singapore.
He was the invited SDA Masterclass Speaker at the 2014 combined scientific meeting on Orofacial Pain, jointly organised by the Pain Association of Singapore and the Singapore Dental Association.

His continued participation in academia has been in the role of external examiner for PhD and MSc research projects conducted in the Department of Restorative Dentistry, National University of Singapore.
His role as Clinical Director of the T32 Specialist Division, is but the logical extension of his personal commitment to the development of evidence-based dentistry in Singapore and the region.
Dr, Tay is a keen golfer and has made pilgrimages to courses like St. Andrew’s, Gleneagles, K Club, Valderrama and Pebble Beach. He plays off a single handicap and loves to go for constitutional walks with O.B., his faithful, slobbering chocolate Labrador retriever.
