I started oil pulling with coconut oil about a month and a half ago and i've really noticed a difference in my ec. I also started brushing twice a day and lately i've been trying to brush 3 times a day. Maintaining a good oral hygiene has been helping my lips a lot especially since when I first got ec i wasn't brushing my teeth as much. I truly believe oil pulling has helped me, but although I have seen improvement I am still not cured. I feel like i'm missing a good moisturizer but i'm not a big fan of vaseline or aquaphor since they make my buildup all soft, white & mushy like and it easily comes off. That's why I ordered some bepanthen(the nappy care one) since it sounds promising but unfortunately it's going to take about a month to get to me so I need to find a good moisturizer until then.
I highly recommend oil pulling though, if you search it online you'll find many pages stating all the benefits you get from it. I didn't believe it at first but since i had already bought coconut oil from a while back, i thought i might as well use it and i truly feel like it has helped me.
