I haven't been to the dentist in over 3 years. I was in college, and didn't have insurance. Now I've gotten a job and health insurance, I can afford to go. When I scheduled my appointment, I was afraid Dr. Lum would find all sorts of problems and cavities. I was very happy when he told me I should floss more and that was it. He didn't belittle me or give me any stern lectures like a couple of my previous dentists did. He was very nice about. From now on, every 6 months for me!
