Don't worry, it shouldn't take long for your teeth to tighten up with oil pulling. Coconut oil seems to work better than most for that but they all seem to do a good job tightening the teeth.
The Q10 with OP really IS a powerful thing. When's the last time taking COQ10 in the afternoon kept you up all night? OP definitely multiplies the effect. I'm on day 3 of a juice fast and woke up feeling low energy (as expected on a day 3). Reading your post reminded me to do a pull with Q10 and I was feeling pretty normal after that - amazing.
