The worst thing I know is salsa dancers without self-awareness with ponchos, with matching teeth whitening. I do not feel that they are worthy of this god’s gift to mankind, teeth whitening. One interesting thing ; 100 million years ago there were not as many people on Earth. But now there is indeed more, and hence more Puerto Rican salsa dancers without self-awareness with ponchos, with matching teeth whitening. I begin to think of oatmeal , one can see oatmeal as a symbol of both puerto rico and humanity. If you do not add enough syrup to get the cake rather boring and banal. Anyway, I really think that your apperance really gets better if you have white teeth, it’s such a big part of your face. Good teeth are not something you get easily though, you have to work a bit for it.
