many might say its caused by smoking which can be true sometimes but I would say by genetics if u understand where im coming from. a trait tht ur parents or ur ancestor had might of been passed on. a cool fact I learned in college is ur gum can get darker if ur exposed to sunlight alot and just like ur skin gets darker, ur gum will to only if u open ur mouth out doors but as a child's gum gets dark, it tends to stay tht way and poor hygene(smokimg wouldn't help in preventing blk gumz) there are oral diseases out,in this wrld tht would cause ur mouth,rather, to turn different colors, mainly what ever u ingest, because of all of the bacteria and plaque in the mouth. sometimes the food would decay in the mouth, cause extreme breath and strait up nastiness. I actually kno a person who has the same piece of broccoli between his teeth for a good 2weeks and tht broccoli is now blk and nasty lookin. world knows how he is imune to those toxins well,thts enough typing grossed myself out alittle
