Reply to comment by sterlingphoenix in ELI5 - Why can't you just wash away germs on teeth with soap? by wolf_metallo

I get that, but wondering why Dental germs are so hardy? Like you wash hands and they are clean enough, but once you have a cavity on tooth, only way forward is to drill and remove the germs/plauqe etc.

I mean, you can get 100% rid of them, but they'll just come back. Or rather new ones will. Once they've managed to get through the enamel, everything else is relatively soft so you want to plug that up ASAP.
