After your treatment, retainers help maintain your teeth aligned. We offer both removable and fixed. Custom-made for comfort and durability, they prevent shifting and help maintain your smile.

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.

Our 5 Star Experience!

Dr Radu saw me on short notice and was very friendly and helpful. I will come here again for any orthodontic appointments in the future. Thank you
I came in for a consultation and appreciated how thorough and professional the doctor was. The exam was detailed and the doctor took time to carefully evaluate my bite and overall alignment. Everything was explained clearly and I felt listened to and respected during the visit. Thank you for your time and professionalism.
Dr.Corina Radu provided a lot of good information that I needed in order to move forward. She answered a lot of my questions that a lot of orthodontic doctors didn’t know or didn’t care to find out.
Came in to see Dr. Radu for a consult. She is very welcoming and knowledgeable. Would definitely recommend!
Dr radu is the best! I did clear aligners (sure smile) with her and am very happy with the results. Dr radu explained every step very thoroughly and answered all questions. Dr radu and her team are so personable and friendly. I always enjoyed going to my appointments. This was an awesome experience. Thank you!
Dr. Corina Radu is amazing! She’s really good at what she does and she has been a huge help for my daughter and I. She’s very professional and I am very thankful for everything she has done for my family.
Very warm and welcoming, and straight forward with the most helpful treatment plan!
Dr. Radu, Ina, and team are absolutely the best! They took over my orthodontic care from my previous provider. The transition to Dr. Radu's care was seamless. She took my preferences and goals in mind and tailored the program to it. I'm super happy with my smile, bite, and alignment. Put your trust in Dr. Radu, Ina, and team and they will handle the rest!
5/5 best ortho on earth
I’ve had such a positive experience at this clinic! The team has been incredibly supportive and professional, and I’ve seen amazing progress with my aligners. Highly recommend their services!
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!
I went to see Dr. Radu after losing my bottom retainer (from 1991) had come loose after being reinstalled by my general dentist 4 months prior. I thought I was going in to see if I can have it put back in and left that day with a plan for alignment trays.

Pros: Dr. Radu is very direct and honest which I appreciate. She is very thorough in making sure she is doing the best job while ensuring you know what she is doing and why. The Elmhurst location is convenient and close to home. Premier Orthodontics also offered a payment plan which was very helpful.

The only Con for me really was the hours but I made it work because I liked Dr. Radu and her staff so much.

I would highly recommend this office for anyone looking for an amazing orthodontist.
Dr. Radu is a smart, friendly, high-energy orthodontist. She actually listens to your concerns and explains different options, and she adapted a plan that fit my needs pefectly. She genuinely cares about making sure you understand your treatment and wants you to be happy with the results. Her assistants are all very nice, patient and friendly, too.
Amazingly thorough
Dr. Corina Radu is nothing but excellent! I saw her for my consultation today and she is EXTREMELY patient with me throughout the process. She is VERY knowledgeable about my treatment and listened to each and every one of my concerns without any issue. Amazing staff members with even more amazing service! HIGHLY RECOMMEND
I had an amazing experience with dr.radu
Amazing team and friendly receptionist. Thank you for all your help ! The retainers fit great
Dr. Radu and her staff was amazing and professional. She booked us in right away and was great at explaining to my teenagers how to handle their retainers. I am a physician and would highly recommend Dr. Radu for orthodontic care.
Dr Radu is very kind, compassionate and thorough. I believe she strives for perfection in all that she does, besides being a really nice human
I recommend Premier Orthodontics it’s very professional on what they are doing and how are they treating you.
I had a wonderful experience with Dr. Corina and her staff. I moved to Illinois from Florida. I had a very bad and costly experience using a Dentist and not an Orthodontist. Therefore, I had to redo all of my aligners, wear them longer which cost me more money for the mistake. However, Dr Corina made it very convenient for me by making installment payments. She is very patient and caring. I highly recommend Premier Orthodontist.

She was incredibly knowledgeable and I could tell she really wanted to help me with the right decision.

I had a great experience with Dr. Corina. Not only did she provide excellent care and treatment, but she also took the time to answer any questions and address any concerns I had. The office staff was very friendly and efficient, making scheduling appointment a breeze. I am very happy with the treatment I am receiving and would highly recommend Dr. Corina to anyone in need of orthodontic care.
Dr Radu is very professional and honest, she gave a through consultation and even contacted my periodontist and general dentist before giving her opinion on what could be done with my poor teeth after a general dentist messed them up. I dont know when I'll be able invest and start again in ortho work, but I would completely trust her to have my best interests at heart.
Dr Corina is amazing, I was probably one of her though cases, but after 4 years of treatment I’m very happy with the outcome without having to do a surgery. She is very professional, passionate about her work and she cares about her patients. I highly recommend her. Thank you Dr Corina!

Dr. Radu Was close to our home, which I appreciated! My son had an expander phase, and then braces. When it came time to do the braces, Dr. Radu offered him a highbred option that worked really well! The office staff is friendly and professional.
Dr Radu is the best! My daughter has the perfect smile and can’t wait for my son to get started on his treatment.
