Dr. Collins All White Bleaching System 22% Carbamide Peroxide

I have the 22% version. It's really potent. I have to use it every other day on account of it burns my gums. However, that's more the fault of the trays that didn't mold correctly to my teeth. I put them in boiling water to form them. That was a mistake.. The water was too hot and the trays didn't mold correctly. I've ordered more and will do them correctly this time. In the meantime, I use a Q-tip and paint the gel onto my teeth, then put the tray in to help prevent the gel from oozing over the top of the tray onto my gum, or from touching the inside of my lips. Because it will cause some irritation. But as far as whitening goes - I've used Crest White Strips, one of the whitener kits that has ultraviolet light, and a slew of different whitening kinds of toothpaste. None of them work as well as this product has worked. If you have any tooth sensitivity at all, I recommend using Sensodyne for a week or so before you start using this to help. This stuff is strong, but it works really really well.

Time directions not included clearly enough. I did not use longer than recommended but caused bleeding gums which forced me to stop and was weeks to heal.

Did not get the desired effects and burned my gums. Had to take it off before the allotted time because it was burning my gums too much.

If you follow the instruction, the product works perfectly, without any undesired effect.

Where to begin? If you're expecting these mouth trays to fit, skip those expectations. I heated it in a pot of water until it was smoking hot. I pressed the trays into my teeth but it doesn't adjust horizontally. The trays still protruded away from my teeth. In order for the product to work, it has to come in contact with your teeth. You aren't bleaching the surface chewing landscape, and that's the only part that will FIT. Because the trays are perched away from contact with the teeth, any solution you have in the tray will leech out the back as you try to SUCK the trays to make contact with your teeth. Biggest bunch of garbage for a high price. Skip it please, this is nothing but a waste of your hard earned money.

I have never tried to whiten my teeth in my more than 50 years. Before dropping big dollars on a dentist, I wanted to try some more affordable solutions. Grocery store brands did little, so after so e research I tried Dr. Collins. The package arrived quickly, good shipping there. The instructions were easy to follow. The mouthpiece is like the ones I used in my younger years playing sports, so that was simple also. The first treatment was interesting. It was easy to start. Had a little tingling, burning sensation where some of the product got on my gums, but that went away quickly, and no harm to my mouth. I kept it in for an hour while watching a game. Other than wanting to drool all over the place, it was easy. The results were pretty good. I would say my teeth were several shades whiter. I was wondering if there wouldn't be a difference in one front tooth that has a crown, but so far, no problem. I recommend this for a starter on whitening. I will post again after a few months for further rusults.

DID NOT AT ALL WORK!

I haven't had the time to use it yet, but feel I will really like it. I'm pleased with the speed with which I received it.
