how about a poll for when ppl have stuff in their teeth? and a bunch people know about it, should you tell the person? or wait all day and let more and more people notice it???
as for bad breath, i try and always chew gum so i guess im self consious, but ill usually try and be discrete about letting them know, you know offering some mouthwash, a toothbrush and toothpaste or maybe even referring them to a dentist
