About

Cl A/Prof Chen Nah Nah is a Senior Consultant from the Endodontic Unit, Department of Restorative Dentistry, National Dental Centre Singapore. 

Prof Chen believes oral health is an integral part of total health. Having a healthy, intact and problem-free dentition is essential for the maintenance of good general health and it contributes greatly towards the well- being of the individual. In this aspect, endodontics strives to conserve teeth where and when possible and I am committed to its cause.
