I got my braces off about a year ago after wearing them for more than two years. I was given a permanent retainer at the bottom part and a removable one on top. After about four months, I accidentally broke the permanent one off. I thought it was not a big deal and since my teeth were already straight, I didn't mind consulting the orthodontist about it and I even stopped wearing the removable one.
Last month, I began to notice that my two bottom front teeth have backward a little. The said I could have again or he can give me a removable spring retainer. I chose the latter because it is cheaper. Has anyone else used this? How long I should wait before I see visual results? I've had the retainer for about 6 days so far. Thanks a lot!
