I had a wonderful experience with Chad Johnson and his staff. My son had a great journey through all stages of his braces. I am super happy with the end results.

Before & After

Overbite Correction & Orthodontics

This patient’s smile transformation focused on correcting a significant overbite and aligning crowded teeth. Orthodontic treatment carefully repositioned the bite, improving both function and facial balance, while also straightening the teeth for a more harmonious appearance. The final result is a healthier, more confident smile that enhances both comfort and aesthetics.

We'd love to hear from you!

The first step toward achieving a beautiful, healthy smile is to schedule an appointment.
