I stopped wearing my retainers 5 years ago. Around the time that I was pregnant with Tucker. It took about that long for my teeth to start shifting. My front teeth started to cross. I thought I would just live with it but they started to hurt. So I went back to the orthodontist and I am back to wearing retainers. A see through plastic retainer on the top and the tiny one on the bottom. I look silly, and sound sillier. My kids laugh. I console myself with the fact that my kids are seeing a great example of what not to do.
