HI Thank for asking to HCM I can really appreciate your concern, there is no home remedy for pyorrhea you have to follow the advise given by the Dentist, this is common belief that cleaning the teeth loose the teeth, in fact these was already being loosen due to the formation of tart, the tart only gives them little support otherwise they are loosely attached with the sockets, if you do not clean your teeth then they will start falling slowly one by one even causing lot of bad breath and infection too, so it is much better to follow the advise if your dentist, have nice day,
