What We Do Best at

Washington Orthodontics

Our orthodontic practice specializes in identifying and fixing dental issues with your teeth. ⁤⁤We offer treatment options for crooked teeth, misaligned teeth, spaces between teeth, overbites, underbites, crossbites, and open bites. ⁤⁤We use modern dental appliances like traditional braces and clear aligners to shift your teeth into proper alignment gently.⁤⁤

Our goal is to not only enhance your smile but also improve your overall oral health. ⁤⁤Straighter teeth are easier to clean, reducing the chances of tooth decay and gum disease. ⁤⁤We create personalized treatment plans for each patient, whether kids, teens, or adults, to ensure the best results for a beautiful and healthy smile. ⁤

Invisalign

Braces

Mouthguards

Retainers

We are a proud certified provider of Invisalign, an orthodontic treatment that uses clear aligners to straighten teeth without metal 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.
