My retainer for my top teeth broke about a couple months ago and I've only been wearing the top broken retainer occasionally. I didn't tell anyone that my retainer broke because i didn't want my parents to get mad because of the replacement cost. I have my retainer check up in 2 days and my top 2 teeth have shifted. I was a scared stupid teenager so I didn't do anything about it. Whats the best way to handle this situation?? Any recommendations?
