The three key reasons for the treatment are:
- To encourage the growth of healthy new gum tissue
- To prevent further gum recession avoiding further exposure of the roots
- To reduce sensitivity which is a symptom of receding gums
"Before getting a gum graft, your dentist will evaluate your smile and attempt to treat your gum disease without surgery. If your gum disease is caught early, a root planing and scaling (in other words, a deep cleaning) may be all that's needed to remove the infection and restore your smile back to normal."
