Smile,
It’s Free Therapy
Welcome to my blog about all things ortho! I’m Dr. Courtney Barry, board-certified orthodontist and founder of Smile Pop in NYC, and this is where I answer the questions you ask me every day in the chair.
Expect real talk on clear aligners, attachments, refinements, retainers and whitening, plus what it’s actually like to straighten your smile while living your busy New York City life.
Some days I talk teeth. Other days I talk trash (kidding!)! Grab some popcorn and enjoy! And if you’re looking for some more educational entertainment, check out my YouTube channel, too.
