I’ve been wearing these retainers at night for the past 10 months, and they’re still looking pretty clean.
Before my operation I had a retainer on my top teeth for a while. One day, this retainer started collecting a little bit of plaque on it, and I thought it would be a good idea to clean it out with a strong-flavoured mouthwash (not naming brands). This looked like it did the trick, then only a couple of days later the plaque marks were back, only worse. The situation with that retainer never improved, but luckily I didn’t have it for much longer. It seems as if the mouthwash corroded the plastic slightly, allowing the plaque to collect on the surface easier.
I’m not making the same mistake with my new set of retainers. The trick seems to be to only ever clean them out using water and a toothbrush. No mouthwash or toothpaste, just water. So far, it’s been working very well.
But seriously though, if that’s what happens when you bathe your retainers in mouthwash, just imagine what that mouthwash does to your teeth!
