I've come across with instances where I use "between" when i should use "among" I've learnt that it's between two things, and it's among more than two things like, between you and I, among the three of us, etc.
Then, how come we say "between the teeth" when we're referring to more than two teeth?
So if there are 32 teeth in human,
if I say between the teeth, am I referring to 30 spaces by saying "between the teeth"? (16 teeth up and down = 15 spaces in between)
