I just quickly grab some shit off the shelf, and as a result probably have not used the same kind twice in a row. the toothpaste aisle has become a neverending wall of bullshit.
there's this really really cheap shit that is one of the best i've ever used. i just can't remember what it's called because i can't find it here.
I use sensodine and it is Bangin! So does my 74 year old father, he has all of his teeth still (though they are getting old) so it really helps them feel a little betta.
