What areas do you serve?

Honolulu extends from Kahala northeast wards through Mililani, making these places accessible throughout Oahu, with Caswell Orthodontics proudly servicing families residing there. Exceptional orthodontic care is what we dedicate ourselves to delivering for the island community as a whole.

How can I schedule an appointment?

At what age should my child visit an orthodontist?

The American Association of Orthodontists advises that children undergo their first orthodontic evaluation no later than age 7. At Caswell Orthodontics, we prioritize early assessment and diagnosis so we can address any developing problems and avoid interventions later on. This allows us to determine the most effective intervention strategies. For more information, Learn more

What is the difference between braces and clear Aligners?

Braces are more versatile because they can treat a wider variety of complex cases. They consist of brackets bonded to teeth connected by wires. Clear aligners, such as Invisalign®, are more discrete as they can be removed, making them appealing for treatment among older adolescents and adults.
