You will need to mash up one ripe strawberry and add in 1/2 tablespoon of baking soda. Then use a soft toothbrush to spread the mixture onto your teeth.
Leave on for 5 minutes, then brush thoroughly with toothpaste to remove the berry–baking powder mix. Rinse. And floss – get out all strawberry seeds. Do not use everyday because acid strips off enamel!
