Brushing the teeth with soap
Alternative Lifestyles and Subcultures
I haven't touched commercial toothpaste in over 4 months!
I alternate between Dr Bronners Liquid Castile Soap (baby mild) and Toothy Tabs (little tablet like things that you chew on then brush) from LUSH. Both the soap and the tabs leave my mouth feeling awesomely clean and have no flouride in them. The only reasons I would pick the Toothy Tabs over the soap is because you can get interesting flavours and the packaging goes straight in the compost bin.
The taste of the soap didn't bother me at all! Just be carefull you only use a small drop of the castile soap otherwise you end up with a mouthful of foam :p
They both vegan friendly so thats a thumbs up for me!
