Dr. Nammy Patel, founder of Green Dentistry in San Francisco, and author of the bestselling book Age With Style— A Guide to a Youthful Smile and Healthy Living, discusses how many visits it takes to get a crown.

So in my practice, it only takes one visit to get a crown. That’s it. And the beauty of that is because we have a 3D printer. And what that does, we take an image of the existing tooth and we’re able to use a 3D milling unit. And then we bake it. And then, voila. You have a whole new crown, which is awesome because you don’t have to worry about getting numbed up again. It’s also time effective, cost effective, and it’ll last a really long time.
