How does celebrity keep their teeth so white?Watch
Can't say I've ever tried smiling like my favourite celebrities though. That sounds so strange.
It never occurred to me.
In fact I’ve never tried to emulate one in any way.
However, whitening on that level is done by an orthodontist. With chemicals that weaken your teeth and can make them very sensitive and in some cases be painful.
Don’t waste money on whitening toothpaste. It doesn’t work.
Make your teeth the best they can be by brushing regularly to remove stains.
A hint of a tan gives the illusion of whiter teeth, natural, fake or bronzer, as does a lipstick with a pink base.
Many regions of the US have fluoridated water by default, so they usually just have somewhat healthier teeth than British folks no matter what (it's fairly uncommon in the UK as I understand; I think Birmingham might have fluoridated water, and maybe one or two other places, but otherwise...). It's also more common to have e.g. braces and similar orthodontistry when you're younger in the US (it seems a bit more varied here) which while that doesn't affect whiteness, people in the US often have straighter teeth as a result which can be perceived as a "better" smile.
Additionally, you can buy those Crest whitestrips in the US, which anyone can get in a shop easily (including celebrities; I believe Chris Pratt talked about starting to use them at one point after he began working out for his Marvel career post-Parks and Rec). As far as I know they don't sell them in the UK (I think they're specifically not legal to be sold here), and I don't know if it's possible to get them as e.g. a prescription or something.
A combination of all of those things means people from (or living in) the US in general have whiter and/or "better" teeth than in the UK, and celebrities in particular will have more resources to correct and/or maintain any cosmetic "defects" they perceive in their teeth (and are, by virtue of their profession, somewhat behooved to do so).
Also I stopped using flouride toothpaste and I filter my water now. fluoride makes my teeth sensitive lol. If I go back to using fluoride toothpaste it takes 2 days before I start feeling pain in my teeth when I drink cold water.
I've looked up the reason. flouride gets absorbed by the teeth and gums and damages the insides making your teeth more porous.
