Response to 29 Horrible Things That Happen When You Put Your Retainer In For The First Time In Forever:
If it doesn’t feel really tight when you put it on each night, I think you’ll be all right. If it’s a tight or painful fit, then you may want to wear it more. I don’t think everyone’s mouth is totally the same (nor is the advice they get from their orthodontist). I remember hearing someone say that they were still wearing their retainer all day six months or so after having their braces off. I only wore mine all day for maybe 6-8 weeks before my orthodontist suggested switching to nights only. For me, the hardest part of the retainer was dealing with taking it out to eat, and feeling like I couldn’t speak clearly with it in. Wearing it at night has been easy by comparison, and I still wear it most nights almost 3 years later. If you have a routine that works for you and that you can stick with, you’ll probably be fine. If you keep wearing it less and less and stop wearing it frequently enough to avoid tightness, then you’ll be at risk of your teeth migrating.
