Tooth ligament and tongue pain.

Does anyone have chronic mouth pain? I’ve suffered for almost 20 years with this and I am really frustrated by it. I will go and get bite adjustments, which help, but then another part of my mouth will hurt. My tongue hurts too..usually on the side and is worse with movement six as talking, eating. I’ve seen an orthodontist and am thinking of getting braces, but wonder if it will help. I don’t want to spend $7,000 and make that comment if it won’t help.
Any insight is appreciated.
Thank you!
