Nathan Swanson might be the greenest dentist in the state of New Hampshire … or the whole country. His practice, Newmarket Dental, reduces radiation by using a digital X-ray sensor, hands out toothbrushes made with recycled yogurt containers, and is on its way to being a paperless office. Swanson can’t make getting your teeth cleaned more fun, but he can make it greener. Check out the video to find out how he does it.
