Good Morning, here are two more logo concepts. I was thinking that you can incorporate the smiley face as a mascot. Maybe print some stickers in different colors to identify the progress on the braces timeline. Since people remember colors and shapes before they can read, having a positive icon, "smiling" will help identify your practice among all other, especially when doing local advertising. If you have any questions, I will be more than happy to help you in the process.
Thank you, and have a great day.
Don
