You're brushing with tea tree oil and Dr Bronners? No wonder your teeth are sensitive - do you have moss growing on those suc***s? JK
Seriously that's pretty strong stuff to brush your teeth with everyday. You'll find that OP is so effective for oral health and teeth cleaning that you can ease up on the tooth brushing. Definitely use as mild a toothpaste as possible - OP will take care of the rest.
Like many of us you'll probably even decide to cut down on the number of times a day you brush. I'm down to once a day after the morning pull and I think others do the same.
