Catherine’s method involves just rubbing your teeth with strawberries, while Tyra mashes up a few strawberries and rubs the mixture all over her teeth.

To try it yourself:

  1. Crush a few strawberries into a pulp.
  2. Use a soft toothbrush to spread the mixture onto your teeth and leave for 3-5 minutes.
  3. Rinse and brush after with toothpaste, and floss out any lurking strawberry seeds.

Strawberries aren’t as effective as bicarb soda or other whitening ingredients, but they are super cheap and tasty, you’d be crazy not to try it.

Beware, the acid in strawberries can damage the enamel of your teeth if you are berry-generous in this teeth whitening treatment.
