Elle Macpherson shares how she maintains her iconic smile. Elle Macpherson has revealed how she manages to keep her teeth clean, white and toxin free.

The 54-year-old supermodel swears by oil pulling, a health practice that involves swilling a spoonful of oil around your mouth.

In an interview with US talk show Megyn Kelly Today, she says that it has ‘done wonders’ for her teeth and gums.

“It’s actually a common practice and a very old-fashioned practice. It’s not, you know, hocus pocus. It’s something that people have done for a long time.”

Macpherson likes to use coconut oil and will keep the oil in her mouth for 10 minutes each morning.

Her theory is that it helps to get rid of toxins ‘through the mouth’.

She isn’t the only one who swears by the practice. Gwyneth Paltrow and Shailene Woodley also do it.
