It’s the failure of the Soviet education system. If we can characterize the Soviet people, it is that they are far too naive.
Eh. They were in a bad spot economically due to Saudi market manipulation at the behest of the west, a military defeat in Afghanistan, a space-race posturing/propaganda. They definitely could have held out longer but they were on the back-foot and were opting for a peaceful/graceful loss rather than forcing a military loss. This worked for the West also as they didn't want to involve their direct military which is why they extended a "peaceful" option for ending the cold war. The icing on the cake was Gorbachev was an intelligence asset (someone linked evidence for this here once, I lost the bookmark apparently; if he wasn't then he was the only truly naive Soviet citizen).
Hopefully it's just a non-critical tooth that needs an extraction.
I think my tooth extraction was like $35 - obviously they'll take on some other fees but the process itself could be quickly fundraised.
The main problem is you might get mis-diagnosed a few times - especially if the professionals are trying to "save the tooth". I was about to get a full root canal when the endodontist finally discovered that the tooth was cracked all the way through the roots and required extraction. Dude, saved me a ton of time and money and that was after like 3 mis-diagnoses.
Sorry you are going through this, tooth pain is miserable.
