Orthodontic Treatment Options for Every Smile

At Premier Orthodontics, we design customized treatment plans based on your bite, alignment, and long-term stability goals.

Metal and Clear Braces

Traditional and clear braces are effective for correcting even the most complex bite and alignment issues. Our systems are designed for comfort, control, and predictable results.

SureSmile® Clear Aligners

They offer a discreet alternative to braces. Each custom-made aligner gently moves your teeth into place, helping you achieve a straight smile without visible brackets or wires.

Airway Orthodontics

Airway-focused orthodontic care supports healthy breathing, proper jaw development, and overall wellness while creating balanced, confident smiles. Start your treatment!

Surgical Orthodontics

Surgical orthodontics helps correct severe bite or jaw issues using advanced digital planning and collaboration with oral surgeons for improved function and facial balance.

Smiles for Every Age

At Premier Orthodontics, we design personalized treatment plans for every stage of life, focusing on healthy bite development and long-term stability.

  • Children: Early orthodontic evaluations help guide jaw growth, create space for erupting teeth, and reduce the need for more complex treatment later.
  • Teens: Braces or SureSmile® clear aligners provide reliable, efficient correction for crowding, spacing, and bite concerns while fitting into busy school and activity schedules.
  • Adults: It’s never too late to improve your smile. Discreet options like ceramic braces or clear aligners allow adults to straighten teeth comfortably and confidently.

Orthodontic treatment does more than improve appearance. It supports proper jaw function, balanced bite alignment, and long-term oral health.

Clean environment as well.

Dr. Radu worked with me for years on my jaw surgery journey, something I'd put off for a lifetime because of how uncomfortable orthodontics can be. I'm so thankful I found Dr. Radu, she is an absolute pro who is passionate about the discipline as well as kind and compassionate with her patients. I truly wouldn't recommend anyone else.

Dr. Radu is a great orthodontist. My treatment took about 1.5 years with lots of different devices in my mouth. Dr. Radu made sure they felt as comfortable as possible while still being efficient. The technicians are also really good. My teeth look great!

We had a great experience with Dr. Radu. She did the orthodontic treatment for both our kids. She went above and beyond to accomodate the appointments to our schedule. Very patient, thorough and efficient, explains everything in detail. The older one is done with his brackets, the result is amazing. The younger one is progressing nicely. When I asked her opinion for myself, she immediately did a comprehensive exam and explained all the options, without pushing for an immediate decision. Overall, I highly recommend this office.

Dr. Radu is an absolute gem! I had an incredible experience as a patient with braces for about 18 months. She’s incredibly knowledgeable and straightforward. If you follow her instructions, like avoiding foods that can break brackets and wearing rubber bands and retainers as prescribed, the whole process will be a breeze. Her entire staff is super friendly and easy to work with, and I never had a hassle scheduling follow-up appointments, even when my retainer broke two days before I left for school. I can’t recommend her enough!
