Weird question, is there a toothpaste with no flavouring?

I hate having any flavour in my mouth if it isn't from food. I hate gum and most drinks for the same reason, I just can't.

This makes brushing my teeth extremely unpleasant no matter what flavour the toothpaste is. I found a mouthwash that barely tastes of anything, but im still lost for toothpaste.
