Sorbitol’s Interaction with Cavity-Causing Bacteria

Most dental care companies make toothpaste and oral care products using sorbitol. However, studies show that sorbitol feeds the bacteria that cause cavities.  Researchers have found that Strep. mutans metabolizes,  lives off of, and thrives on sorbitol. Why would mainstream dental care companies sell products that feed the bacteria we are trying to get rid of?

Spry products are all sorbitol-free. We don’t want to feed the bacteria.
