Soft tissue grafts can be used to increase gum tissue thickness or possibly cover exposed roots where gum is absent due to excessive gingival recession. During this procedure your periodontist takes gum tissue from your palate or another donor source to augment tissue thickness or cover the exposed root if possible.
A soft tissue graft can help inhibit further recession. In some cases it can cover exposed roots. This may reduce tooth sensitivity and improve esthetics of your smile.
