MySweetSmile Precision Whitening Pen – Whiter Smile in 10 Minutes – Targets Stains On Crooked & Crowded Teeth – Dentist-Approved & Enamel-Safe – IndyBest Award-Winning Brand – Fresh Mint Flavour

This actually works. Having tried 3 other makes I read the reviews for this one. I have only used it for 2 weeks and already it’s made a difference, and has even whitened the white filling on a front tooth that was discoloured. My teeth had aged, yellowed and were patchy. But after a week of using this, my teeth became brighter and more evenly coloured. After the second week they were visibly whiter. I still feel they could be better so I don’t mind carrying on with this and I will update my review in one month. It’s definitely worth a try, hope this helps make someone’s mind up.

Didn't seem to work well. Kept turning the top to release gel.It only worked once.

It makes the teeth whiter from first use removes stains needs to be used regularly tastes ok will keep using and would recommend if you want brighter stain free teeth

I have used the powder whitener in this brand which does offer some improvement in stain removal. However, this pen simply does not work for me - not one tiny bit. It ran out after just a few days as there is only a small amount. It slides off the teeth and instead sits down in the gums for the requisite 10 minutes.

Great product

Doesn't achieve a whiter smile within 10 minutes once you close your mouth, as the gel, which doesn't bond to the tooth, just dissolves away. I will persist with it as it's paid for, and maybe constant use produces results, but after two days, they don't look whiter, just being honest

Okay teeth whitener but it's not ideal. It only lightens stained areas a little but doesn't fully remove them. The taste is nice though.

It's brilliant
