Colgate Max White Overnight Teeth Whitening Serum - Home Teeth Whitening Pen - Reverses 15 Years of Stains* While You Sleep - New and Improved Applicator - Enamel-Safe - Easy to Use

Really good everyday toothpaste. Leaves my teeth feeling clean and smooth and helps keep stains under control with regular use. I noticed whitening effect if you use it for a week. Doesn’t feel harsh and works well for daily brushing. Happy with the it

This product is not as a dream solution as most might think it is. The application is pretty annoying but it'll do. One of my complaints is that during the process, I would wake up with extremely white spots on my teeth, however this was not my teeth getting white but just the cristalized cerum on my teeth, which I could only remove by picking at it with my nails. If I'm being honest, Im not sure it's worth your money.

Subtle improvement after 6 uses. You need to make sure teeth are dry before applying. Leaves a strange dry residue on teeth and lips (if they come into contact). I will keep trying.

Works surprisingly well Great for the odd darker tooth but is also amazing for overall use A but hard to brush off but easily pick off with nails + I have sensitive gums and this did NOT harm them at all

Been using this a while now, and not noticed a difference in appearance with my teeth at all. The brush clogs up, you can't see where you've brushed it on, if not careful when using on your teeth you get it on your lips and it stings and takes a while to pull off almost like you've glued your lips (you don't need lip fillers put it that way) Not effective at all. Pretty bland when it comes to taste as there isn't much. Top put in a nutshell it don't work so don't bother with it. My teeth aint the best but they ain't bad either and not noticed a change of colour at all

Tasted ok, easy to use but ultimately not effective at all

Pleased with this purchase, it’s good quality, it’s a very thick Texture, it’s effective, withe a whitening effect, and the taste is quite strong.

I found this toothpaste worked well and my teeth did look cleaner and brighter with regular use. The taste is quite salty, which personally I didn’t mind, but it definitely isn’t one teenagers would like. in my case they wouldn’t use it at all (which was fine, as it’s not aimed at children anyway). My main issue was the packaging. The product eventually leaked out through the lid, which was messy and annoying, especially for something stored in a bathroom cabinet. If you’re an adult who doesn’t mind a stronger, salty taste, the toothpaste itself is decent, but the lid design lets it down.

It is not working
