If I'm a poorfag who cannot afford a dentist's visit and I have the beginnings of a cavity on one of my molars. What's the best way to do a DIY filling until I can afford to have it done properly? Would sterilizing it with alcohol or hydrogen peroxide, then applying a drop of super glue work? I read that this is a bad idea because bacteria can (and will eventually) infiltrate under the super glue, and that the tooth will continue to deteriorate underneath, but I don't have a lot of options at the moment. I have basic hygiene bits & bobs and am currently living out of my car, so my budget is limited, but I could get some cheap supplies at a drug store.
