Doing my first oil-pulling today (swishing coconut oil in my mouth for 15 minutes to gradually whiten them), any tips?

any tips

If I wanted to whiten teeth at home -- I don't, but if I did -- I'd probably use those whitening strips, which it looks like use hydrogen peroxide.

Coconut oil is what movie theaters use on popcorn and IMHO is the best use for it if you've got some. I used to keep a jar of it along with some Flavacol to get the movie-theater experience.

EDIT: I later switched to a mix of chili oil and olive oil for popcorn, which is not as authentic but can be misted with a mister without congealing in the mister and is also pretty good.
