Welcome To Our Office!

Thank you for visiting the website of James A Grabow DDS MS, an Orthodontic Specialist committed to creating beautiful, confident smiles throughout Tuolumne and Calaveras County.

Dr. Grabow and his staff desire to give their patients the best Orthodontic Specialty care available. We understand how important a straight, beautiful smile is, which is why we offer the following state-of-the-art appliances and revolutionary services:

In-Ovation R

In-Ovation “R” is a revolutionary new system of braces that is not only faster for your orthodontist to use, it also can significantly shorten treatment time. It’s great looking and smaller for greater comfort. Plus, it offers better hygiene than conventional braces. To learn more, please visit the GAC website.

Orthopedic Growth Modification

Growth modification is part of the first phase of orthodontic treatment. Growth modification is only possible while bones are still growing. We utilize growth modification appliances (for example: Twin Block and palatal expanders) to change the position, shape, length, or width of the jawbone.


A modern alternative to traditional braces, the Invisalign® system straightens your teeth using a series of clear, customized removable appliances called aligners.

Orthognathic Surgery

To treat abnormalities of the facial bones, which cause pain and difficulty eating, speaking and sleeping, we sometimes recommend orthognathic surgery, also known as corrective jaw surgery.

At James A Grabow DDS MS, your smile is our top priority! We are delighted to provide you the compassionate, personalized care you deserve at each visit.
