After 9 years of not wearing my Orthodontic Retainer my teeth are shifting...help!?

I started wearing braces 12 years ago. After two years of treatment I was given a retainer and told after six months I only needed to wear it at night. After about a year and a half I stopped wearing it. Now, about 9 years later my teeth have started shifting. It isn't something that is visible but it feels different and I don't want to let it get to a point where I need to go through the whole braces thing all over again. I pulled out my old retainers and cleaned them tonight and tried to put them on but they would not fit at all. What is the cost of having new molds taken and new retainers made? Is it necessary or am I just being a little too vain? Thanks for your answers I look forward to hearing them! Oh and a little more information if it helps... I had braces to make room for molars not to straighten severely crooked teeth or a horrible bite problem.

As your molars came in things may have started to shift a little, this is normal, however if you dont want to start over again you need to get to the orthodontist and have another one made and wear it every night for the rest of your life. Teeth will always move. Plus it is recommended to have them adjusted at least once a year to stay tight and keep their form. New retainers can cost anywhere from 200-400 dollars depending on what you get. Your not vain, you know what it is like to have to wear the braces and surely you dont want that time and money to go down the drains.....
