Frenectomy & Skin Graft

My dentist recommends a frenectomy & skin graft for a receding gum line on lower tooth. I would appreciate information on the success rate of this procedure. Will the frenectomy result in my lower lip drooping? Any questions I should ask my periodonist prior to this procedure? How long should I expect discomfort and/or pain?
Thank you for your comments.

Free connective tissue graft generally yields promising result. Frenectomy generally doea'nt affect lip contour. Post-op pain is minimal.As long as your periodontist is competent, there is nothong to worry.

1)  I am not familiar with the terminology you used: what is "free"connective tissue graft?
2)  Since they are cutting the connector between lip and bottom teeth I am concerned it will "loosen" the lower lip, don't want a droopy lip.

I am supposed to have a competent periodontist.
Just me worrying about something I have so little information.
Thanks for all your comments.

The donor site of graft tissue is taken from palate, in stead of skin. Lower lip will not droop due to frenectomy procedure. This is a minor surgical procedure.
