My son just got upper braces put on. I have nothing but amazing things to say about... the wonderful person who put them on him! She was always checking in with him to make sure everything was okay. I would definitely give her her credit for an amazing job, but I forgot her name. Thank you Orthodontic Associates for a great first impression on my son, with braces. I was worried about how he would handle them, but it turns out I was worried for nothing.read more
