Caused a huge blister
I was excited to try a tooth whitening product at home. when I first received the package I noticed it said FDA-registered and not FDA-approved. Those are very different designations. anyone can register with the FDA, there is no criteria. Approval requires something entirely different. Against my better judgment I decided to try the whitening kit and I regret it. I used it exactly as described and was very careful not to put too much whitening product in the trays or allow any to overflow onto my gums. unfortunately some of the peroxide solution must have snuck out of the trays and burned my mouth so badly that I have a blister larger than the size of my thumbnail inside my mouth. I had to toss the product and did not experience any whitening from the three sessions I completed.
