Oil pulling

The practise of swishing oil around in your mouth for 15 - 20 minutes a day is an Ayurvedic folk remedy and said to be a miraculous way to cleanse the body of toxins. Advocates say that it can whiten teeth, freshen breath, prevent cavities, and cleanse your body of various toxins.

However, the detoxifying effect is yet to be shown in clinical trials. There is some evidence that oil pulling can help with oral hygiene, but mainstream dentists don't see it as a good substitute for toothpaste.

There are few documented harms that can come from this practice.
