in his book 'Oil pulling' from 2016

Mouthwash reduces dental plaque by 20-26% and gingivitis by about 13%. Brushing teeth reduces plaque by 11-27% and gingivitis by about 8-23%, Oil pulling beats both methods in effectiveness. Data shows that oil pulling reduces dental plaque by 18-30% and gingivitis by an astonishing 52-60%. Oil pulling therefore has a significantly better result than brushing teeth and using mouthwash.
