Effervess 02 Professional Tooth Whitening Gel | Professional Strength| 50ml Airless Pump Dispenser Provides Months of Whitening |Just Add to Toothbrush

This product really works! I've only been using it for a few days and I can already tell a difference. I had stains inbetween my teeth close to the gum line, and they seem like they are going away (at least they aren't as bad), and my teeth in general look whiter. I put a little on my toothbrush with the toothpaste and brush for 2 minutes, then hold the paste/Effervess in my mouth for an extra minute then spit/rinse. It leaves your mouth fresh and teeth really smooth, just like after a dental cleaning. I have an appointment with my dentist in 3 weeks and I'm curious to hear what they have to say. I've been using this twice a day so it should last for a few months I would think. I will update this post after I've been using it for a few weeks. I highly recommend buying this, as I think it's worth the money and much cheaper than having trays made and buying from the dentist.

Used for 2 week and had to stop as my gums were bleeding in my sleep. I followed directions and did various things, but gums were too sensitive, I guess. Will not reorder.

Leaves my breath fresher than just toothpaste, but doesn't seem to be making them any whiter, despite my dedicated twice daily use. Will use the tube but will not buy again.

My husband and I had two different experiences with this product. His teeth became very noticeably whiter in a short period of time. On the other hand, I didn't notice any difference in my own teeth. It may be because I don't have the patience to leave it on for a few minutes like the instructions say to do.

I bought this for me and the stuff is great! It does what it says it does on your teeth. I saw the difference right away the first day. Yes I would recommend this product , although the price is a little steep but worth it if you have that kind of money to spend for a great smile.

I could not see any difference in my teeth. Also, it was too harsh for my sensitive teeth. I had to stop using it. Will not buy again.

Really didn't work for me I did as per instruction but doesn't whiten my teeth

I would buy it again!
