Welcome to Penrith Smiles

Penrith Smiles is a modern and progressive specialist orthodontic practice. Dr Jonathan Chi is a registered specialist orthodontist. We keep up to date with the latest orthodontic procedures and products to ensure a faster and more comfortable treatment period.  Our state of the art facilities are custom designed with patient friendliness and comfort in mind.  We pride ourselves in the quality of our work, and whilst the pursuit of excellence is our primary goal, we want your orthodontic treatment to be a positive experience for both you and your family.


Orthodontics is a great way to increase your self-confidence, improve your dental health and create a beautiful smile you can share with everyone that you meet. Our practice is proud to provide orthodontic treatment for all ages - from young children to the older adult. Dr Jonathan Chi and his caring team understand this and utilise new and innovative technology, to make your orthodontic treatment less time consuming and more comfortable than ever before.


Starting orthodontic treatment can be confusing, as choices and treatment decisions vary. The team at Penrith Smiles will help you to make an informed decision about the health and appearance of your smile. We will work with you, as a team, to achieve optimal results.


Dr Jonathan Chi established Penrith Smiles as a Specialist Orthodontic Practice over 23 years ago. Since then it has grown to be one of the largest orthodontic practices in the Penrith region.


Penrith Smiles is a tertiary orthodontics referral treatment centre that receives referrals from oral-maxillofacial and ENT surgeons, general medical practitioners and in addition to other orthodontists in NSW who do not provide combined surgical-orthodontic treatments. Dr Chi is a Medicare registered Cleft Lip and Palate services provider.
