Washington, Mar.29: Gwyneth Paltrow and Shailene Woodley recently shared their love for the all-natural teeth-whitening trick known as "oil pulling".
The Academy Award winner actress told E! News that she had just started 'oil pulling', which is when one swish coconut oil around in mouth for 20 minutes, and it was supposed to be great for oral health and making teeth white.
The 'Divergent' star said that it really makes teeth whiter, because the plaque on teeth is not water soluble; it's fat-soluble so the lipids have to dissolve in fats, which is why oil works in your mouth, Us Magazine reported.
Dr. Marc Lowenberg, a New York City-based cosmetic dentist said that it was probably the most harmless natural remedy. (ANI)
