Turns out that your oil pulling practice may need a tech upgrade. According to a recent study presented at the Society for General Microbiology’s conference at the University of Warwick, coconut oil could be super beneficial to your pearly whites, but only when modified with enzymes.

The study: Researchers from Ireland’s Athlone Institute of Technology wanted to see if coconut oil could prevent Streptococcus bacteria from spreading through the mouth and causing tooth decay. They tested pure coconut oil and coconut oil modified with enzymes (similar to partially-digested coconut oil) to see if they stopped the bacteria from wreaking havoc.

The results: While the regular coconut oil didn’t stop the growth of Streptococcus, the enzyme-modified coconut oil did.

What it means:  The researchers believe that enzyme-modified coconut oil could potentially make its way into dental products in the near future, replacing the current common chemicals in your toothpaste—like triclosan—that you’re rightly afraid to swallow. —Allison Becker
