Toothpaste and IF

Doesn't having to use toothpaste just overwhelm you and make you feel sick? Part of why I'm doing keto and sorta IF is because I'm healing my gums, which involves a lot of brushing, flossing, rinsing, etc. But I have to say, first thing in the morning when I fill my mouth with this crap, I think it's starting digestion after a little while of the taste being in my mouth, and it's hurting my stomach.
