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).
Sometimes dentists will combine ultrasonic with mechanical methods, like dental chisels, to remove plaque below the gumline [source: Turchetta ]. While root planing and scaling are not high-risk procedures, there is a risk of infection in the gums.To prevent infection after the procedure, your dentist might insert antibiotic fibers into your gums which come out about a week after the procedure.hen your dentist does your root planing, he'll essentially be gently sanding your teeth, removing rough spots on the tooth surfaces and roots, which tend to harbor bacteria [source: University of Maryland Medical Center ].
