Moderate gum disease is treated with a procedure known as "scaling and root planing". Treatment usually involves one-quarter or one-half of your mouth at a time. The area to be treated is thoroughly numbed and your plaque and tartar buildup are removed from beneath your gumline and from your roots. It's important to note that after any advanced gum therapy you need to see your hygienist every three months for maintenance. If not, your gum disease will return - and worsen.
