Due to its widespreadness is getting your teeth bleached really cheap in the USA? I can't say I know hoe much it costs in Germany, but I don't think most public insurances are covering it so people probably don't really do it. Although I think I see many native Germans with rather white teeth, but I am not sure if they somehow 'did' something. I wonder what the normal tone of color for teeth is whem you brush 2x times a day and drink coffee in the morning and maybe some tea here and there.
Additionally I wonder if US expats living in Germany still get their teeth bleached and therefore maybe introducing the normalization of those pearl whites.
