Bests & Worsts Reviews from Amazon

UPDATE- 6 months later and only had to do a couple trays as touch up before the crown. Overall still very happy with the result of they whitening trays...... ORIGINAL- I was given some samples of these trays by my dentist in preparation for a front tooth crown. After doing some research, I found them here on Amazon for slightly cheaper than the dentist. The taste of the trays when they are on your teeth isnt that bad at all. It's when your taking them off the texture of the gel kind of surprises you. The first time I used it, I think I may have burned a spot on my gumline(a clump of the gel got wedged right on the gumline). It turned white for a couple minutes but turned to red shortly after (rinsed with salt water the next couple days to help heal it up). Also took a couple days break from the trays. If your gums have sharp-like stinging try to bend the tray down and off your gumline(first couple times you might still get some white spots on your gum, but if you pull it off the gumline right when it starts stinging it stops it from burning it and the white gum spots will go away after a minute or two). Another tip: found it is better not to brush your teeth prior, don't need to irritate your gums and then add hydrogen peroxide to it... Don't be afaid to take a couple days break between trays if your gums are getting sensitive. By the end half of the 10 day set, I didnt have anymore gum sensitivity/ white gum spots. Also with the first few times you might get these weird looking bright white spots on your teeth (middle picture), dont worry its temporary and mine faded over night. Overall im very happy with the results. Happy enough to buy this brands matching Whitening toothpaste (it has a nice mild taste and they also have sensitive toothpaste). And beware it doesn't whiten any fillings. Since the entire front side of my one front tooth is filling(thats the one getting the crown), it did not get any whiter. But it does make a nice color comparison in the after picture (the filling use to match my other teeth quite nicely). My dentist also warned me that I will have to use a tray every couple months to keep up that shade of white and prevent staining in order to match my front tooth crown(whitening results are not permanent, but can keep a nice look with a little upkeep). Otherwise my dentist suggests hydrogen peroxide mouthwash/ toothpaste to help keep up if you want to use the trays less often. Hope my learning curve helps you out.
