Happy Braces off day to Kim's daughter, Scarlett!

Scarlett wanted to let everyone know that she only broke one bracket during her time in braces, because she ate a candy cane like she wasn't suppose to, and to remind everyone to stay away from candy canes this holiday season 🤣

10/16/2025

Spooky season is here! 🎃 🪦 👻
It feels wrong decorating for Halloween when it's 80 degrees outside 😂

10/13/2025

Halloween is coming! Patients in braces can still enjoy lots of candy, like Reese's, Hershey's, York, 3 Musketeers, and more. Avoid sticky, chewy, crunchy candy like Milk Duds, Nerds, Caramel, etc. Everything in our Witch's Brew cauldron is ortho-approved👌🏻🦷

10/07/2025

Our Halloween contest starts today! Guess how many marshmallows are in the jar to win a $50 gift card AND an electric toothbrush OR water flosser!
Make your guess in-office, via email, or social media. Contest ends Oct 31. Contest limited to patients, please 😁
Good luck! ☠️🎃👻🖤🧡
