Perfect toothpaste

[Hawrie]

How come nobody has invented the perfect toothpaste - whitest teeth, freshest breath and tightest gums - all-in-one?

I would assume it's not possible, as the active ingredients in the seperate products may react together when mixed. I'm not sure.

The toothpaste companies are prevented from lying this much. saying youll have white teeth OR fresh breath is on the limits, saying their product is perfect is going too far.
