I should have kept my very last invisalign temporary trays, but my permanent ones work just fine. Seeing my dentist in April and will ask about making up another temp set. This product is just right! I used a higher concentration - 30% I think - and it caused a lot of discomfort to my gums. Sticking with this.

I have been using this product for several years -- always with good results. Initially, I used it every day / every other day until my teeth were the color I wanted. Now I use it once or twice a month for maintenance. It has done wonders for my smile and my self-confidence.

Have tried numerous teeth whiteners but always return to Opalescence PF 20%. I highly recommend it for people that are tired of the goo strips. Just make sure that you have good fitting trays.

I have been using Opalescence 20% for years and regularly (about every 3 months) use it to help remove stains from my teeth. It is a good product and is a good value, used approx. ever 2- 3 months it is almost a year's worth of treatment. I use it in my tray overnight, ever other night so that my gums do not become sensitive.
