Did you use olive oil when you pulled in the past? It's thick texture and strong taste turns a lot of people off and it can discolor teeth. But my favorite is flax seed oil which a lot of people also think is too strong tasting.

I'm convinced that regular oil pulling is much better than teeth cleaning (even if you had it once a month). It cleans out nasty germs where cleaning can't reach and what it does for the gums is near miraculous. Your mouth really does feel the difference when you've stopped for awhile. They must call it pulling because it keeps pulling you back... lol
