Gum disease treatment
Gum disease starts quietly — a little bleeding when you brush — and can end in loose teeth. Found early, it is very treatable.

Signs to watch for
Gums that bleed when you brush or floss, redness or swelling, bad breath that does not go away, and gums that seem to be pulling back from the teeth.
How it is treated
Early gum disease often clears with a professional cleaning and better care at home. Deeper cleaning below the gum line treats more advanced disease, followed by regular check-ups.
