Dd has just got her braces off and is thrilled with the results 
She went back the next day to have a removable retainer fitted. She has to wear it every night and it has to be in for 12 hours. I'm very worried about the teeth moving back, they said that even after the braces come off, the teeth already start to move a tiny bit and it's really important to wear the retainer every day.
They've said she can switch to a permanent bar if this one doesn't suit her.
What's best or is it down to the individual? How important is the 12 hour period? It's a bit tricky with mealtimes etc. We eat around 6.30/7pm so she could put it in after that but will then need to take it out to clean her teeth at bedtime!
Any tips please?
