Your Top-Rated Orthodontist in Iowa City, IA

“I love this place, I recently finished my treatment and when I tell you the way my teeth started out compared to how they are right now…it’s absolutely a dramatic change. I always wondered what id look like with a smile that I actually liked myself and now I know and I find any reason to smile and I’m confident when I do so. The staff are amazing and Dr Mergen is so professional and so kind.”

“This is a great place to go! Everyone is really friendly. I would highly recommend this place to everyone. So far I am very pleased with the results. If you need anything or notice any problems they are very prompt in fixing things or adjusting even if you don’t have an appointment. Choose Mergen for a great smile!”

“Best orthodontist I’ve ever been too. They have quick and easy appointments and even help to give different payment options on certain things such as Invisalign. The staff there along with the orthodontist are amazing and caring. Wouldn’t go to any other place but Mergen Orthodontics!”

shelley m review

“Dr. Mergen and his team was absolutely incredible! I had such an amazing experience. The staff is incredibly friendly and makes you feel at home. I began my treatment with Dr. Mergen and about half way through, I moved to Atlanta. The flexibility offered with this team is SUPERB. I didn’t need to end treatment and start over; I was able to continue my treatment while in a different city and came back only once for a second scan. If I could give this a 10 star rating, I would – this comes a lot from someone who works in customer service!”
