Is sharp gum pain after an in-office tooth whitening with a dentist a concern?

I just received a whitening treatment today at my dentist and only my gum around my canine hurts. It’s a sharp jolt of pain that randomly occurs, it’s not very red or swollen just the pain. The dentist said I had two “sore” spots and the canine is one of them but the other spot is pain free. Is this normal? And what can I do for the pain? Ibuprofen 600mg and Tylenol 500mg isn’t working. Thank you!!
