No idea but I note this claims to clear up 15 years' worth of staining... unfortunately I have 40 years' worth of tea staining to combat, so I'm not sure it's strong enough for me! Seriously though, this Colgate product contains hydrogen peroxide, which is what's traditionally in hair bleach, I believe, and quite a strong chemical? And it says don't get it into contact with water... so what about the saliva in your mouth while it's on your teeth all night, isn't that basically water?

Same reason you don't apply paint to a wet surface but don't care if it rains after it's dry, I think.

The obvious answer is to go to your dentist I would think.

I had my lower teeth re-aligned a few years ago by my local dentist practise and included within that was whitening, I didn't think they were that bad but before and after demonstrated the difference.

I didn't go overboard like you see some people do just to improve them somewhat. I don't think tooth paste actually does anything as it's on and then rinsed off, whereas professional whitening involved having a gum shield scanned and created bespoke for each set of teeth, you then add a small amount of whitening gel to each tooth within the gum shield and then put in your mouth overnight.

Obviously you need to clean your teeth before inserting these (and dry your teeth), my teeth are quite sensitive so I opted for a low % gel and did one night on, one night off, maybe two if they were too sensitive. Probably took a few weeks before I could start to tell the difference.

Heavy tea drinker here and I just get a clean at the dentists every year.
They offer something like a jetwash blasting the stains off rather than chemicals. Costs something like 40 quid and is well worth it.
They always offer extra stuff to do at home to get them whiter but as a middle fat balding bloke having turkey teeth isn't really top of my list.
