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).
Periodontists also offer a number of treatments that can improve the appearance of your smile and resolve some dental problems. If you have gum recession, for example, gum graft surgery can be used to cover the exposed roots of teeth with healthy gum tissueâyour own tissue, or processed material from a donor.
