Braces Treatment

Braces Treatment

Considering braces? Treatment starts with a careful evaluation of your bite. We design a personalized plan, fit the right type of braces for your case, and guide you through every adjustment to a fully aligned smile. Consistent care and follow-through are what deliver lasting results

Clear Aligners (Invisalign)

Clear Aligners (Invisalign)

Considering clear aligners? The right plan starts with a thorough evaluation. We assess your case, design a custom aligner sequence, and guide you through treatment to deliver predictable results. Consistent wear and proper planning are what turn aligners into a lasting smile

Preventive Orthodontics

Preventive Orthodontics

Wondering when your child should first see an orthodontist? Early evaluation is key. We assess jaw growth, tooth eruption, and habits that can affect alignment, then monitor development and step in only when needed. Catching issues early keeps future treatment shorter, simpler, and less invasive

Learn More
Interceptive Orthodontics

Interceptive Orthodontics

Worried about your child's developing bite or crowded teeth? Early evaluation is key. We assess jaw growth and tooth eruption, then use targeted appliances like expanders, space maintainers, or growth modification therapy to guide development before problems become harder to fix. Acting at the right age makes future treatment shorter and simpler

Learn More
Corrective Orthodontics

Corrective Orthodontics

Dealing with crowded teeth, a misaligned bite, or a jaw discrepancy? Accurate diagnosis comes first. We evaluate the case in full, design a targeted treatment plan, and guide you through the right combination of braces, aligners, or surgical orthodontics to correct the problem. Consistent care and proper retention are what make the result last

Learn More
Retention Therapy

Retention Therapy

Just finished braces or clear aligners? Retention is what protects your results. We fit you with the right type of retainer and monitor your alignment over time to prevent relapse. Consistent retention is the difference between a temporary fix and a lasting smile

Frequently asked
questions

Getting started is simple. Schedule a free consultation at any of our three Oahu locations: Honolulu, Kahala, or Mililani. During your visit, Dr. Caswell or Dr. Tada will evaluate your smile, answer all your questions, and walk you through the treatment options that fit your goals and lifestyle. Schedule a Consultation today.
Absolutely. We welcome patients of all ages at Caswell Orthodontics. Our team is especially known for being patient and caring with younger patients, making every visit feel comfortable and fun. Whether your child needs early interceptive care or you are an adult ready for your dream smile, we have a personalized plan for you. Schedule a Consultation to get started.
Braces use brackets and wires to move teeth and are a great fit for patients of all ages, including children and teens. We use advanced 3M and LightForce 3D bracket systems for precise, efficient results. Invisalign uses a series of clear, removable aligners and is a popular choice for older teens and adults who prefer a more discreet option. During your free consultation, we will help you decide which treatment is the best match for your smile and your life.
Treatment length varies depending on the complexity of your case and the type of treatment you choose. Most patients complete active treatment in 12 to 24 months. After your initial exam, Dr. Caswell or Dr. Tada will give you a personalized timeline so you know exactly what to expect from start to finish. Schedule a Consultation to learn more.
It is normal to feel some mild soreness for a day or two after adjustments, but most patients find it very manageable. Our team takes a gentle, stress-free approach and will always make sure you feel at ease. We are happy to walk you through what to expect at every stage so there are no surprises. Learn more about our patient-first approach.
Once your active treatment is complete, we move into retention therapy to protect your results. You will receive a custom retainer to keep your smile looking its best for years to come. We will guide you through exactly how and when to wear it so your new smile stays in place. Have questions? Contact our team anytime.

Insurance & Payment options

Every patient deserves a confident smile regardless of budget. Invisalign treatment typically runs $2,650 to $7,000, depending on the complexity of your case. We work with most major insurance plans and verify your coverage before treatment begins.

For out-of-pocket costs, we offer CareCredit financing and in-house plans with transparent pricing, built around your goals, timeline, and budget. Our team will walk you through every option so you can focus on your smile, not the paperwork.
