Why are some people gums brown and some are pink, and why do some pink gums have brown spots on them?

Question

I have also noticed that some people with brown gums have really pretty teeth too.

Answer 1

Yeah i have noticed it too but i am not sure either. when someone has like brown gums or something sometimes its like a problem or a disease  

Answer 2

It is just pigmentation--like some people have freckles. The pigment is more concentrated...  Usually a darker skinned person will have darker gums, though not always.
