well i think i started oil pulling too late for it to make a difference, plus my molar was cracked, so it had to come out.
i have not oil pulled consistently for a long period of time to really be able to say how much difference it would make - but i remember that when i oil pulled, my mouth felt so noticeably "clean"... and when i stopped oil pulling, no amount of brushing etc. made me feel the same level of cleanliness, so that's why i would like to go back to oil pulling.
