I do not plan on going back ever if I can help it, unless i lose a big filling or crown. My teeth are healthier than they have ever been and look that way also. There is no reason to go back IMO. I am also frustrated with the problems that going to the Dentist has caused me. I do not know what chemicals they used to clean my teeth but I never felt better after a teeth cleaning. I only felt worse. Not so with oilpulling. I always feel good after oilpulling.
