Review: GREAT product and works quickly! - This teeth whitening product really impressed me with how quickly and effectively it works. After just a few uses, my teeth looked noticeably brighter and more natural compared to other products I’ve tried. It is quite strong, so it’s important to follow the instructions carefully—using too much or applying it too often can make your gums sensitive. As long as you use the right amount and give it time between treatments, the results are excellent.
Review: Most powerful teeth whitening agent on earth - I've been using Opalescence 35% teeth whitening gel (bleach) since I was 16 and am now in my 30s. If you think $100+ crest white stripes or gimmicky LED light products are the answer... kindly give this a try. Bear in mind you do you need a custom made retainer/teeth tray to use this product. Unlike over the counter teeth whitening products (that just oxidize off stains), Opalescence actually turns your teeth white - if that makes sense. It is a 35% carbamide peroxide, typically dispensed (at inflated prices) at dentist's offices. It comes in 10%, 15%, and 35% variations. The 10% and 15% are meant for overnight. The 35% is for a convenient 30 minutes. This product dramatically bleaches and whitens appearance (in a visibly noticeable fashion) after two or so uses. Consistent use (8-9 times in a row spaced out a few days) will make your teeth glow from outter space. It gives an iridescent optical effect that catches the eye. You will get so many compliments. I'll do it once a year or so and my teeth will be white for like a two years lol. Products incredible. Be cautious not to get the product on your gum line or to leave it on longer than 30 minutes. It will increase teeth sensitivity.

## Questions & Answers

**Q: How often can you use it?**
A: DFW Dental Supplies only sent me 2 syringes. Mike said he would not send my other 2 until I took down a negative review! Not fair!!!!

**Q: whats the difference between 20% and 35 %?**
A: I think the lower strength has to stay on for a longer period of time. When I first started wiih this I kept the trays on for hours and the 35% only stays on for 1/2 hour

**Q: I have a diy mouthguard that i made from a mold. could i use that for the mouth trays or should i buy new trays?**
A: You maybe able to use it as long as there is room for the gel in the tray.

**Q: how long do you leave it on?**
A: I been leave it over night, and according to my dentist that was the cause of my gum damages.35% it’s too much, I should not use more than 15% or even better to be 10%
