I thought that oil pulling was one of those hippie things; might have some benefits and wasn’t harmful as long as you spit the oil out. So if someone wanted to do it, that was cool. But when we were asked I wanted to actually look into it before I answered.
What I found as that oil pulling is actually dangerous. When you suck oil through your teeth it can create tiny bubbles of oil that can get pulled into your lungs. Because our bodies have no way of removing oil from our lungs it can then turn into pneumonia. Because of that risk, we recommend against oil pulling.
