I went to my ortho after loosing my bottom retainer, and she suggested getting a spring retainer to fix a few teeth that moved out of line. Specifically the 4 bottom incisors that are a few millimeters off and on the top one flared incisor and a small gap between the two front incisors. I forgot to ask some questions like how long I would have to use that retainer for and how many hours/day and would I keep that retainer after or get a new clear one like I used to have? How hard is it to talk with the spring retainer? I am used to the clear kind which I have been using for three years. Any info would be appreciated! Thanks!
