Nah, just kidding. But I used to dip a can a day and one day after years of dipping, I just threw it in the trash. That has been like 2 1/2 years ago.........do not miss it a bit. I had 2 root canals because of that crap and at $4 a can, it is a total waste of money.
But you have to want to quit to do it. I honestly had zero problem because I just got tired of doing it.
