well, I have been my own dentist for a long time, I was not in favor of most dentists their procedures for filling up a hole, they remove to much tooth enamel and also their anticipated dental denervation, damaging rooth canal cleanings , and so on and so on , so if I got a hole in my tooth I fill it up myself and also other things, its easy and safe. you can buy these things on the internet. also good for preppers and those things are cheap, you can buy toothfillings on the internet and be safe from tooth pain during whatever plandemonic disaster
