We utilise a holistic approach to perfect the functionality and appearance of your smile

At Ortho3, we strive to provide ethical treatments that exceed the expectations of our patients, parents and referring doctors in a caring and personal environment. Our practice philosophy integrates orthopaedic, orthodontic and orthognathic approaches to correct problems with facial development, bite (malocclusion) and the alignment of teeth. We focus on both functional and aesthetic results, and create individualised treatment incorporating the latest technology to improve your experience.

Dr Kerry Lester personally attends to all patients and is the only consulting and treating specialist Orthodontist across our two boutique practices. Our modern boutique practices are located in two convenient locations across Sydney.

We endeavour to assist in the jaw development of our younger patients to pave them a healthy oral future. Oral concerns are usually intercepted around eight or nine years old when children’s developed bone structure is more pliable.

We offer a range of different orthodontic treatment options to assist our patients in achieving a healthy and aesthetically pleasing smile. Orthodontic treatment can be suited to patients of all ages with our wide range of discreet and effective choices.

To maintain excellent oral health, it is necessary to create a harmony between your jaw and the rest of your facial features. Orthognathic utilises the most accurate surgical methodology to correct disharmonies in your jaw in order to create a balanced facial profile.
