Can alum do the work of tootpast?
I am very lazy when it comes to brushing teeth and don't brush my teeth daily at night and have many fillings in molars. I don't want plaque to be created or any other kind of tooth decay. Can anyone please tell me if I make a mixture of alum i.e. dissolve alum in water and just do mouth gargles (کلی in Urdu) so will this kill germs like bacteria that can damage teeth. If not then is there any easy time saving and cheaper alternative like this so that I only do mouth gargles and there won't be any need of tooth brushing with tooth paste.
I'll be very thankful fot the reply.
