I am 19 years old and a full time student, I had braces when I was 16 for 16 months. After my treatment I had removable retainers which I had to put on for 6 months and then asked to wear every night after that. However, my bottom teeth started to move slightly and now 3 years on my front teeth have come forward a lot more and my wisdom teeth are soon to be visible. So basically I was just wondering if I could have some sort of inexpensive treatment (since I would have to pay now) where my teeth are very straight and afterwards have a fixed retainer which would keep my teeth straight always? Any suggestions? I am lacking confidence because every time I try to smile or look in the mirror or even bite together since I can feel my upper and lower teeth touch each other.
