i'm a hygienist and it's usually from stain or tartar...could be coffee, tea, soda, red wine, TOBACCO...some people just have darker enamel..but if it's that bad they are probably just dirty :)

smoking, drinking coffee or tea, or not brushing which will cause them to turn yellow. Of course not brushing them too will cause them to turn yellow and/or black which probably means they are rotting away.

Ive noticed that alot of meth addicts get black teeth.....because of the chemicals making their teeth rot.

it's from not brushing your teeth enough. it's plaque buildup that just stains your teeth because it's there for too long.

they dont brush their teeth and they probably are a smoker and they dont really go and see the dentist very often.
