Gum disease is an inflammation of the gum line that can progress to affect the
bone that surrounds and supports your teeth. The three stages of gum
disease — from least to most severe — are gingivitis, periodontitis and
advanced periodontitis.

Gum disease can be painless, so it is important to be aware of any of the
following symptoms:  Swollen, red, tender or bleeding gums  Gums that recede or move away from the tooth  Gums that recede or move away from the tooth  Persistent bad breath or bad taste in mouth  Loose teeth  Visible pus surrounding the teeth and gums

On average, seeing a dentist twice a year works well for many people. Some
can get away with fewer visits. Others may need more frequent visits. People
with very little risk of cavities or gum disease can do fine seeing their dentist
just once a year. People with a high risk of dental disease might need to visit
every three or four months, or more. This high-risk group includes:  Smokers  Pregnant women  Diabetics  People with current gum disease  People with a weak immune response to bacterial infection  People who tend to get cavities or build up plaque
