Inconsolable teething pain

Hi there. My 6 month old daughter has been teething for at least three months now but never has cried uncontrollably about it until last night. I’d put her on the carpet with her toys and back up to see what she’d do and at first we thought it was the beginning of separation anxiety but then when I’d be in view, she’d continue to cry. My husband and I gave her a piece of celery to chew on and that slightly helped. This morning, we could not get her to calm down from crying. She was inconsolable, she was insulted we gave her the celery and threw it on the ground. She also will not let us massage her gums. We had to give her a dose of Tylenol. She’s currently sleeping but does anyone have any suggestions on what they do for “the gum owies”. Thank you so much!
