Hey i'm cat and I need some help, :cry:

i have terrible tooth pain. I recently have been to see a dentist (with great force) and had some work done on my teeth. But the problem stems back further I had a wisdom tooth which cracked and eventually it got filled with a filing. The dentist said that the wisdom tooth wasnt growing anymore so I ruled out my pain coming from that. The pain takes up the whole right side of my mouth and its the gums that hurt ive tried almost everything im terrified of dentists and cant face going back to have my teeth either tuck out or drilled open or even x-rayed my gums are killing me sometimes for a while like a couple of weeks the pain will go away but then it comes back. I had a few years where I hardly ever brushed my teeth and am only just starting to get into the routine as from today in fact. My gums are killing me and the only pain relief I get is from pain killers and stuff like creams you can put on your gums. I am trying mouth wash and stuff but I dont know wether it will help. I dont know what it might be does anyone have any ideas I just dont know what to do anymore im so depressed and in alot of pain please some help please
