The only thing you have to do is get the baking soda in where it can do its job. The small heads of the rotary power brushes don't carry much so I use a regular brush to load my teeth with the soda and then use the power brush—which is better for cleaning and getting down into the gums—for working it in.
Thank you for answering so quickly. I love your comment about dumping large, poison rocks on the spirochetes.
No comment on it’s perhaps being too late because I’m so old? If I get dotty, I suppose I won’t care anyway, LOL!
