How to make cavity filling at home and other things to use to close a cavity?

Cavities. You can use whatever you want at home to fill the cavity..Bubble gum, wax, plaster of paris. However, none of these will stop the decay, repair the decay, solve the problem. You need to see a dentist for this. I hope you realize i was just being sarcastic. There are otc repair kits at most pharmacies- however, this is just a temporary fix and i find patients do more harm than good with these kits.
