Driven by his passion for cosmetic dentistry, Dr HS Chai travels frequently to attend continuing education courses all over the world. Despite his vast experience in practice he is a strong believer that certain techniques used in the past are no longer relevant in current practice today. He advocates that dental technology is constantly evolving and in order for patients to receive the best dental care and to achieve the best possible result, dental practitioners have to undergo extensive training. In his free time, he enjoys a game of golf, travelling and keeping fit.
