How is gum graft surgery performed? During gum grafting surgery, a periodontist will commonly take connective tissue from the roof of the mouth (palate) and suture it to the affected gumline. This allows more tissue to grow and close the exposed root surface (gum recession).
When the tooth was originally removed and bone graft material place, the stitches came loose and bone graft material came out in my mouth (very foul smelling/tasting). The dentist placed 'beneseal' over the area and told me to try not to touch the area with my tongue. Eventually, the opening healed. Since he put in the implant (same appt as the bone graft and sinus lift) that area has been tender along the gumline, it throbs and is painful sometimes.
