Colgate Max White Ultimate Overnight Teeth Whitening Pen, Reverses 15 Years of Stains* 2.5ml, 1 Pack, 35 Nightly Treatments

Reviews on this product seem varied but for a tenner I thought it was worth a try. I find the pen very easy to use. The gel cleans off my teeth easily the next morning with my electric toothbrush. I have found the results good - basically I have one tooth that is slightly yellower than my other teeth and my dentist is unsure how effective professional teeth whitening will be on this tooth as it may not be surface discolouration. Rather than spend £500 on professional whitening that may not work I thought I'd try this pen first and I'm pleased to say that it has helped my teeth to look brighter and more uniform in colour. I have used alongside a colgate whitening toothpaste as recommended.

This product is O.K but a little disappointing, I do not think the product has a lasting effect on the teethQuick to apply - not too effective.

• Its safe to say that this product is the worst purchase I have ever made. A complete waste of money.• The paste itself creates an awful texture on your teeth- it goes on like a liquid, hardens, and some of it begins crumbling off whilst other parts of it doesnt come off at all, even when brushing your teeth. After they said "brush teeth like normal!" Would remove it in the morning- Absolute bull****. I had to sit scraping it off my teeth.• If the paste touches your gums, which happens easier than you think, it immediately dries like super glue, and is an absolute nightmare to get off. The liquid dripped down whilst applying to my bottom teeth and immediately began burning my gums, forcing me to shut my mouth with how painful it was. The pain and burning was so bad it brought me to TEARS. Never in a million years would I think buying a simple product from amazon would be this awful!Apon closing my mouth, the substance fused the inside of my bottom lip to my teeth meaning I had to rip them apart from eachother! My mouth was sore all day and, thankfully, has now healed after 2 days. I wish I had taken a photo for the review but quite frankly, I dont think anyone would want to see sore gums.• In terms of actual whitening, I have only used this product once so am unsure on the actual results you get after the amount of days it recommends but no one in their right minds would want to continue after this first experience.• The reviews are right about the applicator being easy and the use is simple and that would be wonderful if the product wasn't so f****** awful!!• when I read the bad reviews I still went ahead and bought it because I thought they were being dramatic. Worst decision I have ever made.PLEASE do not waste your money on this- i don't want anyone to go through what i did. it is dangerous and by far the worst outcome I could have ever imagined. If you really want whitened teeth im sure there is something out there that doesn't burn and superglue your gums together!

Easy to use if a bit messy, but makes your teeth whiter after a couple of days, they're noticeably whiter. An effective tooth whitening system. It does leave a scale/film on the teeth, which you mostly get rid of when brushing in the morning.

i bought this item because i seen all the four and five star reviews, what i didn't look at was these were all from people how received it for free, I've since noticed that the reviews from people actually buying the product are much lower.I was looking forward to the item as it wasn't too pricey, and from what i read, it was easy to use.the item comes in a small box, which not too many instructions, but when you use it the first time, you'll get rid of the paper box, so next time you want to read anything, there are no instructions on the product itself!the thing is easy to use, click he button a few times until you see a bit of fluid on the bristles then just brush it on.however, after only a few uses, the brush clumps up and you spend more time cleaning it (or trying to) that actually using it.use it for a few more times and its ran out. i got 8 uses out of it before it was dry and ran out.i would have expected it to last longer and not clump up as much, which would have resulted in less product being wasted.as such, its not really long enough to be able to form a proper evaluation on the effectiveness of its whitening abilities, and i don't fancy buying another few of them to be able to gauge the effects long term due to the clumping and time spent trying to clean it.on the other side, its a new to the market product, a few adjustments to make the product better and i genuinely think it would become a permanent third step in my dental routine. until that time, id give this product a miss for now.

Not quite what I expected it drips out very quickly and a lot of white stuff comes off it it feels like jelly and fluff. I’ll keep using it and see how I get on. I suppose it’s good value not sure.

It's don't whiten teeth brought this on 19th Dec not done nothing waste of money

I could see a marked improvement in a short time. Easy to use
