🦷 Dr Collins White Carbamide Peroxide: Achieve Whiter Teeth with Confidence! Review

I whitened my teeth about 15 years ago. I whiten my teeth by 16% every 4-6 months. I ordered dr. Collins and thought I had an obsolete stock. I'm almost done with my second tube and have had minimal results. I've been using it for 6 weeks. My gums have never softened.

I have been using this gel off and on for many years. The dentist made a whitening splint. You can use a football mouthguard as long as you don't leave the house during the bleaching! People always comment on how white my teeth are :)

Not only was the product expired 01/2012 (purchased 08/2013) but the plungers in the bleach syringes popped out and ran into the packaging! Revain credited me for the purchase so everything is fine but I wouldn't buy this. I bought it a long time ago and it worked to whiten my teeth. Revain must have a very old stock!

I used to buy whitening gel from my dentist for $20 a tube, but it's MUCH cheaper and works just as well, if not better. I often get comments about how white my teeth are and I usually only whiten my teeth twice a year (3-4 day cycle). You don't have to use a lot of this gel as it is very strong and if you use too much it can burn your gums. Whatever amount you find necessary, use half that amount. Trust me on that. The gel is long lasting and my teeth are amazingly white.

I opened the product packaging and found a leaking whitening gel. The packaging did not protect either the syringes or their plungers and as a result two of the three syringes lost gel: one lost 2 of its 5 ml, the other 1 of its 5 ml. So in total 3/5 of the contents of the syringe were lost. This could have been avoided if the syringes were in a tray that prevented movement of the plungers.

This is my second purchase from Dr. Collins and I firmly believe it works. I had my teeth professionally whitened 10 years ago, complete with custom trays. My dentist told me that if I used my "splints" after every professional teeth cleaning (3 times a year), my teeth would stay pretty much at their current level. It's true, and for years I've bought my replacement syringes through my dentist. I was hesitant to try another brand but bought Dr. Collins and is happy with the results. I drink…
