Aloe Vera to replace toothpaste

It is a long time I am searching for a way to stop buying toothpaste and do it myself..
I found out recently that a piece of Aloe Vera could replace it and produce some foam if you chew it first and brush with it..
Other ideas to produce your own toothpaste?

 

I hear charcoal is pretty good?

 

You could always grind rocks into a semi-powdery form and use that with water to scrub your teeth.

I knew a girl who didn't brush at all, and just swished coconut oil, and she said she never had a single cavity.
Which is more then I can say. lol
