Use of Green Tea Mouthwash to Reduce Dental Plaque, Gingivitis and Halitosis: Review of the Literature

Study Background: In the case of reducing dental plaque, a green tea mouthwash has been studied alone or combined with other natural agents. Aim: To evaluate the effect of green tea used as a mouthwash for reducing dental plaque, gingivitis and halitosis. Methods: Cochrane database clinical trials published from 2010 to 2020 were reviewed. Studies that met the inclusion criteria were reviewed by 2 authors individually. A qualitative review of the data was performed. Results: Eight studies were included in the systematic review. There was no difference between green tea alone against chlorhexidine. But there were better results when combining green tea with xylitol or Salvadora persica L. extract. Conclusion: Green tea mouthwash may be a viable natural mouthwash and can give better results when combining with other agents.
