The actress who played gum-chewing Violet Beauregarde in the original "Willy Wonka" movie says she went through so much sugary stuff on the set ... she got 13 CAVITIES because of the flick. 

54-year-old former child actress Denise Nickerson claims she blazed through "cartons and cartons and cartons" of Bazooka gum while shooting the 1971 classic ... and ended up with a mouthful of rotting teeth.

The lesson here -- always chew sugarless, kids!
