My wisdom teeth are coming in and starting to shift my upper and lower teeth. My appointment is not until March to get them removed and I am concerned my teeth will continue to move until then. I have my old retainers from when I had braces 15 years ago. I put it on today and it does not fit perfectly and is uncomfortable, but I am willing to endure a little pain if it will help prevent my teeth from becoming even more crooked. What are your suggestions?
