Having watched interviews from the 1980s and 1990s when they had perfect natural teeth and the comments why are they so yellow?
Is it really becoming a thing to have bright white teeth? I've noticed it more that indeed many people I meet, all ages, have these unnatural gloss.
Personally, when I see this, my reaction is nice but it doesn't make a difference unless for medical reasons. In fact I think it's quite a common view that has become a bit mocking.
I'm not saying with any form of malice, just it's so obvious.
