Bleach Pro Whitening Teeth Gel Syringes 22% Carbamide Peroxide, 10 Tooth Bleaching Gel 3ml Syringes

an effective invention..

This takes time like 2-3 hours to notice a decent difference. I like it and it's very mild. Do you time I switched to 36% and am very happy although I have noticable sensitivity...milder but noticable for a few days. Although I see the same results or a bit more in only one hour but will bleach gums. This strength won't badly bleach gums if you get a little on it. Use it for 3hrs then I use a remineralizing paste after to reduce sensitivity made in Switzerland. Not sure if it's great but it seems to help. Don't drink coffee, tea, or wine for 24+ hrs after. I used this with custom fitted trays I had made online. Custom trays cost maybe $120ish but really REALLY get you the great results if you have teeth that aren't in a perfect row. Overall very happy with the gentle results and if you have 3hrs I recommend them.

I would not hesitate to suggest this product. Good value and good product

Feels fine. Teeth bleaching, feels like and is as strong whitening as the $120 set I use to get from dentist

It whitened some but seemed less effective than product I had from dentist (also 22%). I had no trouble with any burning sensation or tooth sensitivity. I agree with previous reviewers that the size of opening is too large. Also product seemed thick even at room temp, so the process of loading the mouth forms was cumbersome. When time to re-order, I will try another product
