I do the xylitol gum! I think countries in asia regularly markets this as part of good dental hygiene for those reasons you listed. Some of the gum containers advertise, white healthy teeth. Not sure why the US doesn’t promote xylitol gum more.

This is for all my floss-averse people out there: put floss plackers in your car. I floss way more this way than in front of my sink. Yes, not optimal dental hygiene but there’s just something that just clicks in my head and makes me want to do it when driving around vs literally any other time.

I’ve never heard of this witchcraft. This is exactly what I need.

Edit: heard not beard
