Tea tree oil is extra healthy for the mouth cavity. This amazing oil regenerates and strengthens the palate, prevents caries and cleans the tongue. Tea tree oil is also great for whitening your teeth.

Research suggests that tea tree oil may fight germs that cause tooth decay and bad breath.

One study found that tea tree oil was more effective against plaque-causing bacteria than chlorhexidine, a common disinfectant and oral rinse. What’s more, its taste was found to be less objectionable.
