“I enjoy my work and I love having the ability to help patients feel confident about their teeth and smile. As a parent myself, I am very patient when I treat children and enjoy giving them a positive experience about dental visits.” Dr Dahal believes in the connection between dental health and overall general health and that everyone deserves a pain-free healthy mouth.
