r. Cheng and his staff are amazing! Everyone who works there is kind and welcoming and his office's are clean and organized. I've been a patient of his for over 5 years now and he has significantly helped improve the overall health of my gums/teeth by providing information about my current health, proper flossing/brushing techniques and common teeth grinding solutions. As long as you hold up your end of the bargain by flossing your teeth daily along with brushing you will prevent a lot issues. I trust Dr. Cheng and his staff because they genuinely want you to look and feel better about your teeth.
