CLAIM: Made with cinnamon oil and coconut oil — said to clean teeth and freshen breath — plus baking soda to whiten teeth.

EXPERT - VERDICT - Bacteria - Mouth - Laboratory

EXPERT VERDICT: This might help kill some harmful bacteria in the mouth: a laboratory study in New Zealand showed cinnamon oil can kill Streptococcus mutans, which causes tooth decay, and Lactobacillus plantarum, which can cause gum disease.
