Qualifications

Dr. Joy Guo is an orthodontist and a DSD Master clinician specializing in adult and pediatric care. She integrates Digital Smile Design into orthodontic planning to coordinate treatments with aesthetic smile goals. Dr. Guo provides clear aligner therapy and fixed braces for patients of all ages.

Orthodontic Specialization and Approach

Dr. Guo treats adult and pediatric cases using a digital-first methodology. This approach prioritizes diagnostic goals over specific appliance selection. The process begins by determining tooth movement, bite construction, and space requirements before choosing braces or aligners. This planning logic ensures that orthodontic results align with long-term stability and aesthetic needs.

For adult patients, Dr. Guo coordinates orthodontics with restorative dentistry. Moving teeth into the correct positions first allows for less invasive tooth reduction during later veneer or crown placement. Additionally, she uses intraoral scans, facial photography, and periodontal imaging to assess bone stability and root positions before starting treatment.

Pediatric Orthodontics

Dr. Guo manages early orthodontic pathways for children during the mixed-dentition stage. She monitors growth timing, oral habits, and bite development to intervene at the most effective clinical stage. Evaluation starts as tooth replacement begins to assess space and the positioning of neighboring teeth.
