We are especially interested in making all our patients feel right at home! We put your needs first to achieve efficient and comprehensive treatment. It is our commitment to provide the most advanced and modern orthodontic care available.

Personalized Orthodontic Solutions for Children, Teens, and Adults
At Thai Orthodontics, we are passionate about transforming smiles and improving lives through expert orthodontic care. Whether you’re a child needing early intervention, a teen exploring braces or clear aligners, or an adult ready to finally get the smile you’ve always wanted, we offer a complete range of advanced orthodontic treatments tailored to every stage of life. Serving the Grove City, Hilliard, and Columbus, Ohio areas, our practice combines compassionate care with leading-edge technology to deliver stunning, lasting results.
Below is a detailed look at the modern orthodontic services we provide:
Invisalign® and Clear Aligners


For patients seeking a subtle, flexible way to straighten their teeth, Invisalign® and other clear aligner systems are a top choice. These custom-made aligners are virtually invisible, allowing you to improve your smile without the appearance of traditional metal braces.
Invisalign treatment uses a series of clear, removable aligners that gradually shift your teeth into alignment. Each set is worn for about one to two weeks, and since there are no brackets or wires, you’ll enjoy the freedom to eat your favorite foods and maintain your regular oral hygiene routine with ease.
At Thai Orthodontics, we are certified providers of Invisalign, offering expert guidance and advanced digital scanning technology to plan your treatment with precision. Clear aligners are a great option for adults and teens who want discreet orthodontic care with results they can feel confident in.
Traditional Metal Braces


Traditional braces are a time-tested, reliable method for correcting misaligned teeth, bite problems, and jaw irregularities. Today’s metal braces are significantly more comfortable and efficient than the bulky versions of the past. They feature smaller, low-profile brackets and heat-activated archwires that apply gentle, consistent pressure to shift teeth effectively.
Braces can treat a wide range of orthodontic issues, including crowded teeth, overbites, underbites, gaps, and crossbites. They are especially useful for complex cases that may not be fully correctable with aligners alone.
We customize each braces treatment plan to the patient’s unique needs. And for those interested in adding a bit of flair, we offer fun elastic color options that allow teens and younger patients to express themselves throughout their orthodontic journey.
Carriere® Distalizer™ Functional Appliance


For patients with bite issues such as Class II malocclusions (where the upper teeth are too far forward), we use the Carriere® Distalizer™ Functional Appliance. This cutting-edge orthodontic device moves upper molars backward into proper alignment—creating the right foundation before braces or aligners are placed.
The Carriere Distalizer offers a less invasive alternative to headgear and can:
- Shorten overall treatment time
- Reduce the need for extractions
- Improve comfort and esthetics during treatment
It’s especially beneficial for younger patients or those with significant bite discrepancies. By correcting the bite early, we can set the stage for a more efficient and effective orthodontic outcome.
Early Orthodontic Treatment


Orthodontic issues often begin developing long before all adult teeth have emerged. That’s why the American Association of Orthodontists recommends that children have their first orthodontic evaluation by age 7.
At Thai Orthodontics, we offer early orthodontic treatment, also known as Phase 1 treatment, to address problems in their early stages—when the jaw and facial bones are still growing and more adaptable. This early intervention can make a big difference in a child’s future smile.
Benefits of early treatment may include:
- Correcting habits such as thumb-sucking or mouth breathing
- Creating space for erupting permanent teeth
- Guiding jaw growth and bite development
- Reducing the need for extractions or surgical procedures later on
Our team will evaluate your child’s smile and determine whether early treatment is necessary, or if periodic monitoring (growth guidance) is the best path forward.
Teen Orthodontics


The teenage years are the most common time to begin full orthodontic treatment. With most permanent teeth in place, teens can benefit from a wide range of orthodontic solutions, including metal braces, clear ceramic braces, and Invisalign Teen®.
We work closely with teens and their families to design a treatment plan that suits their lifestyle and smile goals. Our friendly, supportive team makes the experience fun and empowering—ensuring teens stay motivated and engaged throughout the process.
Adult Orthodontics


You’re never too old to improve your smile. In fact, a growing number of adults are choosing orthodontic treatment to boost their confidence, oral health, and overall quality of life. At Thai Orthodontics, we offer personalized adult orthodontic treatment that fits into your busy schedule.
Many adults prefer discreet options like Invisalign® or clear ceramic braces, which offer a less noticeable appearance while delivering excellent results. Others may benefit from traditional braces depending on their specific dental concerns.
Orthodontic treatment for adults can:
- Improve bite alignment and function
- Enhance facial aesthetics and symmetry
- Reduce risk of gum disease and tooth wear
- Correct shifting that occurred after previous orthodontic treatment
We understand that adult patients may have unique concerns or dental history, and we’re here to help guide you every step of the way with clear communication and exceptional care.
Orthodontic Retention


A beautifully aligned smile is the result of careful planning and treatment—but orthodontic retention is what keeps it that way. After your active treatment phase ends, we provide custom retainers to ensure your teeth remain in their new positions for years to come.
There are several types of retainers available, including:
- Removable clear retainers (similar to Invisalign trays)
- Fixed retainers (bonded to the back of your teeth)
- Traditional Hawley retainers (acrylic and wire)
Our team will help you determine the best retainer type for your needs and provide instructions on how to wear and care for it properly. We also offer ongoing monitoring to make sure your smile stays in great shape.

Thank you for considering Thai Orthodontics for your orthodontic care. We invite you to contact our Grove City or Hilliard orthodontic office to schedule an appointment. It’s a chance for us to get acquainted, and for you to learn about the treatments and services we offer.
We look forward to working with you, and to being a part of this wonderful, life-changing experience.
