We Love to Make You Smile!

Dr. John Mergen and his staff love to put smiles on the faces of the locals...literally! Iowa Citians love their straight teeth so much, they voted Mergen the best place for Orthodontics. “I can’t say enough good things about Dr. Mergen and the team,” gushes Jenni, an Iowa City local. “Since day one everyone has been friendly, professional, and prompt. I am thrilled with the outcome of my Invisalign treatment!”

Patients love the variety of braces that Mergen Orthodontics offers. “I had a great experience as an older person getting braces,” says Travis, another patient. Mergen Orthodontics offer Invisalign, a type of braces that is nearly invisible. Patients like Travis have the option of smiling confidently while their teeth are adjusting.

Locals also love that the staff is kind and accommodating. Jan’s daughter was so nervous and scared when getting braces. “Dr. Mergen and his staff were so wonderfully kind and encouraging to her. She loves the fact that her braces are invisible, and now she can smile!”

"We had a great experience with Mergen. Staff is so wonderful and kind. They treated us like family as we got to know them over all the visits we had. Dr Mergen did a wonderful job. He helped us out whenever we needed it, even taking late night phone calls when we had issues and helping us work through them. I would highly recommend them to anyone. From the first time you walk through the doors to the last time this is easily the best place to have orthodontic work done in my opinion." - Ben, Iowa City Local
