I have been Coconut oil pulling twice a day for almost a month now.
I hope I am not overdoing it.
I would normally just do it once daily but I do still have 1 root canalled filled tooth and it was smelling around that tooth so in the evening I drink a cup of green Tea and then use the tea bag to place between the tooth and gum for an hour. It's much easier than clay.
Then oil pull with 2 drops of oregano oil.
The reason I asked about using Bentonite clay in a mouth guard once weekly was in the hope that it would remineralise teeth and reverse receded gums from past over brushing.
