Hi, homie! ;)
Some of my friends were using tumeric for whitening their teeth and overal gum/ oral care... Never tried it myself, despite I'm very connected with this plant and love to eat it often on my cooked meals...
I've been using oil~pulling before breakfast (right after waking up from sleep)... and this was in the past... regularly with raw sunflower seed or coconut oil...
AMAZING results I could say... for the whole body and mind.... a lot of energy and detox...
Sadly I'm not into such disciplined mode recently... but I can honestly recomend it :)
btw... using bamboo brush and other household products is very practical as it is anti-bacterial as we know! ;)
