Guys I've had dental braces about 8 years ago, took it off after two years and has been told to wear my retainers every night since then. The thing is, I stopped wearing it regularly after three years and now I've completely ignored that piece of plastic. Recently, my concern towards the arrangement of my teeth bloomed again, and I've noticed that my right central incisor teeth has moved and that there's a small gap in between both central incisors.

I wanted to start wearing my retainers again, in fact I've wore it last night, and my oh my, it was a very very painful night to go through. My question is, you guys have any tips on starting to wear the retainers again after a long time of slacking off? Perhaps I should wear it a day full for the starting weeks?
