What We Do Best at

Washington Orthodontics





We are a proud certified provider of Invisalign, an orthodontic treatment that uses clear aligners to straighten teeth without wire and brackets in your mouth. Another benefit is you don’t need to avoid your favorite foods and can maintain good oral hygiene properly. With weekly aligner changes, Invisalign can efficiently straighten your teeth faster.

We provide Invisalign treatment to teens and adults, making it a popular choice for our patients. Using state-of-the-art technology, such as the iTero Element scanner, our orthodontists can create a 3D image of your teeth and map out the customized treatment plan.



At Washington Orthodontics, we provide dental braces to patients of any age. Our orthodontists have many years of experience performing this treatment using advanced technology and techniques. We also understand that every patient is unique, that’s why we personalize our treatment plans to suit each patient’s specific needs.

Custom mouthguards ensure optimal protection and comfort for athletes, teeth grinders, sleep apnea sufferers, TMJ patients, and more. Each mouthguard is crafted to fit the unique contours of your teeth, guaranteeing a snug and secure fit. We use advanced 3D imaging to make the process of being fitted for the mouthguard quick, comfortable and convenient for you.

Both braces and Invisalign require retainers to maintain results following orthodontic treatment. Crafted with precision and using state of the art materials, our custom retainers offer both durability and comfort for everyday wear. Whether you need replacement retainers or a custom retainer created for the first time, we can help to ensure lasting results and a confident smile.
