Invisalign® uses clear plastic aligners to gradually shift your teeth into their optimal position without wires or brackets commonly used in traditional braces


Braces are bonded brackets, arched wires and elastic bands that move crowded or spaced teeth into the proper position for appearance and function.

In-Ovation® System

The In-Ovation system makes braces practically pain free with virtually no pressure placed on your teeth as they are gently guided into place. Contact our team to learn more.

SureSmile® uses 3D imaging to create virtual simulations of how your teeth will shift. In addition, this advanced technology allows us to customize your treatment. Contact our team to learn more.

Sleep Apnea

Early diagnosis and treatment in children are important to prevent complications that can affect children’s growth. We can help fix sleep apnea without the need for a CPAP machine by using SomnoDent Oral Appliances.

TMD & TMJ Disorders

From night guards to protect your teeth at night to orthodontic intervention that includes balancing the surface of your teeth to correct your bite, we do it all. And we want to help you feel better. Contact our team to learn more.

I moved to the San Francisco Bay Area in 2021. Due to the pandemic my daughter was unable to proceed with her treatment plan. With us having to relocate I needed to find a new orthodontist office for my 12 year old daughter as soon as possible. Image orthodontics was conveniently located near us. When I called to schedule they were also accepting new clients. During her first visit they instantly made the both of us feel welcomed. The office was clean and the atmosphere was inviting they went above and beyond with Providing my daughter exceptional care the assistant Sarah was so sweet and attentive making sure she was comfortable. I could tell by the way she was able to converse with me throughout my daughters ortho visit that she was very skilled and educated as a orthodontist assistant even taking some additional time to further explain the after care. Image orthodontics helped provide my daughter phenomenal results and a bright smile for a lifetime
