This does the job that any toothpaste does - it cleans your teeth. The taste isn't overwhelming or intense like some other toothpastes tend to be. It's nice and minty fresh.
In terms of this whitening your teeth... I have been using this for over 4 months and haven't noticed my teeth getting any whiter. To be fair I drink way, way too much coffee and I do smoke.
I wouldn't recommend this as a tooth whitening product but I would recommend this as a toothpaste in general. It isn't anything special but it works and makes your teeth feel nice and clean.
I would use this again (I have it at the moment) because it's a good all round toothpaste with a decent price tag. However, whitening? I didn't find it whitened at all. I've used other pastes which hate whitened more, but cost a lot more money and given me a slimy build up on my inner cheeks and gums. I know that's due to the beach content and that's why they work better than this, but at least this doesn't damage your oral tissue. it cleans well, my teeth feel smooth and I don't get bad breath or tartar build up (but that may be due to my electric tooyhbrush? Don't know). It doesn't whiten that I have noticed, but I'm sure my teeth would probably be less white if I used a non whitening paste. A decent buy for the price, but if you're really concerned about whitening, you'll be dissapointed.
Tips: F you're really after whiter teeth, Colgate max is better, and use it in conjunction with crest 1 hr strips.
