I have dry mouth which makes me prone to bad breath. I’ve experimented with chewing these before bed (after brushing) or in the morning (also after brushing). I tested my breath using a cloth mask and also did “blank” tests on days when I did not use the product. Chewing before bed greatly reduced morning breath but left me with some sour mouth, which makes me worry a bit about tooth decay. I’ve switched to taking in the morning and have been happy with the results.

Lips & mouth sore?

Mouth and lips became sensitive and sore after using this product 2x per day for 3 days. Maybe I’m allergic to one of the ingredients? Don’t know. It’s day 3 of soreness and waiting for it to subside.
