  • Clear retainers!
Size: Overnight Whitening (120 Count)
Didn’t know I need this until I started using the tablets! I wear Invisalign at night. In the morning I put 1 tablet in a small glass of water then drop both retainers in. I let them soak (get clean!) until I put them in again at night. They have NOT degraded my retainers, no taste, no smell, highly effective in cleaning Invisaligns. ... show more

  • The Best!!
Size: Overnight Whitening (120 Count)
I've tried sooo many. These are the best tablets on the market. I have really thick retainers and I was getting tartar build up overnight. I even tried the home remedies. The dentist themselves couldn't even get my retainers this clean. And I've never used them overnight. I just drop them in every morning for at least an hour. Amazing Product! ... show more
