Who We Help
Orthodontics Is For Everyone
We’re passionate about orthodontics, which means we love seeing kids, teens, and adults transform their smiles and grow in confidence throughout the process.
Kids
Early checkups are important for monitoring smile growth and development. We can help you know if and when your child may need orthodontic treatment.
teens
We know how important it is for teens to have a confident, healthy smile. Treatment is meant to be fun and exciting, so teens have options when it comes to treatment!
Adults
It’s never too late to have the perfect smile! Many adults are taking advantage of the opportunity to receive orthodontic care for a perfect smile.
How We Help
Explore Our Treatments
Orthodontic treatment does more than just straighten teeth! While correcting your smile’s appearance, orthodontics can create better function and improve your overall health.
Braces
Whatever your case may be, braces are a well-proven treatment for treating a range of orthodontic issues, and we offer several different styles to choose from.
Invisalign
Invisalign is one of the top teeth straightening systems for all ages, using customized plastic trays that gradually move teeth for the perfect smile.
Other Treatments
We take a comprehensive approach to your treatment and ensure that your treatment plan is 100% customized to you and your specific needs.

✨ Something Special ✨ My family and I stumbled upon a Kindness Rock Project at the PV Mall—where strangers decorate rocks with kind words and uplifting designs. It sparked an idea: why not bring that same warmth to the Beach Cities Ortho team? So, we gathered together for a team-building activity, painting rocks filled with positivity and inspiration. These little works of art now line our office walkway, reminding us every day of the kindness we want to spread, not just within our team but to every smile we care for. 💙 -Dr. Brothers
