Dr. Yajun Cui, DMD, PhD, is a highly trained orthodontic specialist dedicated to creating healthy, confident smiles for patients of all ages. With advanced expertise in braces and Invisalign®, Dr. Cui combines precision, technology, and personalized care to deliver beautiful results.

At Sweet Smiles Orthodontics, we take pride in helping the Belmont community achieve their best smiles through efficient, comfortable, and science-based orthodontic treatment. Dr. Cui’s thoughtful approach ensures every patient receives a plan tailored to their unique needs and goals.

Belmont Braces

Traditional braces remain one of the most reliable and effective orthodontic solutions available. Using a system of brackets, wires, and elastics, braces gently guide teeth into proper alignment over time. Belmont braces are a great option for addressing more complex bite or spacing issues — often achieving faster results than alternative treatments.

At Sweet Smiles Orthodontics, we offer both metal and ceramic braces for a more aesthetic look, providing a cost-effective and proven path to a beautifully straight smile.

Belmont Invisalign®

For patients seeking a discreet and comfortable orthodontic option, Belmont Invisalign® is an excellent choice. This modern system uses a series of custom-made, clear aligners to gradually move your teeth into alignment — without the need for brackets or wires.

Invisalign aligners are removable, nearly invisible, and easy to maintain. To ensure the best results, patients wear their aligners for 20–22 hours per day, changing to a new set every 1–2 weeks as directed by Dr. Cui.

Invisalign® effectively treats many common orthodontic concerns, including crowding, gaps, and mild bite issues. During your free consultation, Dr. Cui will help determine if Invisalign is the right choice for your smile goals.
