Is it true that chewing gum helps eliminates plaque?

only certain kinds , theres only like 3 or so on the market that do that. its not like a pack of juicy fruit is gonna wipe the yellow off your teeth- it aint gonna happen.

That all depends on the brand/type of gum that you get.

only orbit trident and eclipse

i really doubt it, mainly because when you chew gum the gum is on the top of your molars and the part of teeth someone would want to whiten would be the front teeth. Also there is no telling how many pieces it would take to even notice a difference.

I think some brands may help with that.
