ChapmanSmiles Orthodontics is a modern orthodontics practice located in Clackamas and Happy Valley, Oregon. Founded and operated by board-certified orthodontist Gary Chapman, DDS, the practice is dedicated to treating patients with the highest quality care in a relaxed, fun, and friendly environment.

Dr. Chapman and the team at ChapmanSmiles Orthodontics believe everyone deserves individualized care. They never recommend treatment before a full orthodontic evaluation. To ensure their patients always receive quality care, the practice offers free initial consultations for every new patient.

Investing in the latest orthodontic technology is important to the practice. Newer technology results in shorter treatment times, fewer in-office visits, and less pain and discomfort for patients when treating issues like TMJ pain and sleep apnea.

For accelerated orthodontics, the practice uses state-of-the-art orthodontic solutions from Propel® Orthodontics. They also provide Invisalign® and Spark™ clear aligners.

Avoiding tooth extractions is another priority at ChapmanSmiles Orthodontics. Dr. Chapman only recommends extractions when absolutely necessary. The practice encourages early intervention treatments, like palate expanders and Penguin appliances. These devices help prevent overcrowding and misaligned teeth.

The staff at ChapmanSmiles Orthodontics understands that many children, teens, and adults come straight to their office after school or work. For hungry patients, they offer freshly baked chocolate chip cookies and always provide cozy blankets for patient comfort.
