I am the queeeen of dental work; more crowns, root canals, fillings, extractions, all the way to dental implants that required extensive bone grafts, than I can count! Oh the hours I've spent in the chair with novacaine my only friend. The worst I've suffered was a headache after several hours with my jaw locked open.
If you're not going under, there needn't be any real pain after the initial couple of shots. I will stop the dentist in a second if I feel any nerves that haven't deadened completely.
I've never really suffered terribly afterwards, more a dull ache. Good luck, and my thoughts are with you for a speedy healing.
I am very grateful for SR, too.
Hugs,
Donna
