A frenectomy is simply the removal of a frenum in your mouth. A frenum is a muscular attachment between two tissues. You have two ferna (the plural of frenum) in your mouth: one that connects your tongue to the floor of your mouth and another that connects the inside of your upper lip to your gums right above your upper two front teeth. If you have a frenum that occasionally hinders the normal function of your mouth, a frenectomy may be necessary. A frenectomy is a minor surgical procedure that is performed with either a scalpel or laser and takes less than 15 minutes. If you or your child needs a frenectomy, there is nothing to worry about. The procedure is extremely successful and causes minimal discomfort.
