About True North Orthodontics
A snack bar, kids' play area, and home-scanning app via Grin make visits to Dr. Hammer's office feel less like a chore than most orthodontic care.
True North Orthodontics pairs traditional braces and Invisalign with a modern, home-like office that includes a snack and beverage bar and a play area for younger siblings. Reviews highlight the Grin scanning app, which lets patients check in remotely and cuts down on in-office visits for busy families, including some who travel from Superior. Dr. Christine Hammer is described as reassuring and thorough in explaining treatment options, with newer doctor Dr. Heidi Huh also well-liked, and several reviews mention Invisalign being used to address bite and TMJ issues alongside cosmetic goals.

I had such a great experience with True North Orthodontics from start to finish. Everyone there is so nice, welcoming, and easy to work with. They always took the time to answer my questions and made the whole process really easy. I’m in love with how my new smile turned out! Definitely recommend True North if you’re thinking about getting braces! ❤️

After our pediatric dentist recommended an orthodontic consult, we didn’t know where to go. So we shopped around and had consultations at a few area orthodontic practices to compare. True North was easily who we decided to go with and we’re so grateful we did! From their care plan, cost, and overall professional and kind service, we couldn’t be happier! Thank you True North for making our daughter’s new smile journey so enjoyable!

True North has the most amazing team!! Every single person is kind, welcoming, and genuinely engaging. We chose them over other providers because of their personalized approach and the way they make patients feel truly cared for. The grin scan also makes treatment very easy and convenient. Highly recommend!!
