Tooth and Mouth Problems

My dentist has advised me for root canal treatment but i am really scared about the procedure .. i really fear to be on dentist chair and injections😭..will it be really painful after watching several youtube videos i see dentist places some rubber time substance in mouth will it be painful ?

So, since 2-3 says m feeling as if my tongue is getting so dry and my mouth feels so dry, please tel if my tongue is normal or not, i see a white line, i brush daily twice and also use tongue cleaner/scraper every morning to clean it.. please help me as my mouth feels so weird. That white line is there in mouth since quite a time, i am not sure if its thrush or not.

Should I get it removed? That gum hurts a lot when i chew something, it wasn't hurting but started hurting nowadays. I am having tinnitus, can it be because of this? Also i am having impacted wisdom tooth on both sides, bottom right is partially erupted, this pic is left bottom, this weekend i have scheduled to get the right top one reduced as its bucally erupted... I am scared :(... and can these be the reason why m getting hyperpigmentation on my buccal mucosa?

I could see teeth discoloration for two teeth. All teeth are white. This teeth is yellow and white spots
