Please consider using Fluoride free tooth paste and stop drinking fluoride infused water.
Nana is currently liking Toms ok but there are many others you can try Hello, Toms, Red Seal, Jason Seal. Check it out.
Fluoride is so toxic that it has to be handled in ways similar to nuclear waste prior to dumbing that shit in products they poison us with.
It also messes up your pineal gland, in hopes of preventing you from using your God connection,

I've used fluoride free toothpaste for over 30 years & first filtered my water but now I have a water distiller
I also take Borax (20 Mule Team) - a little over 1/4 tsp a day. Not only good for teeth & bones but helps to decalcify the pineal gland - fluoride can calcify that gland over time

Also a note to tea lovers: black tea has quite a bit of fluoride, and green tea contains some as well. I've preferred herbal & floral teas for a long time so it doesn't really affect me to leave those out but I know a lot of people swear by green tea so this is just a heads up
