Gum Disease
Gum disease begins when plaque builds up along and under your gum line. Plaque causes an infection that hurts the gum and bone that hold your teeth in place. A mild form of gum disease may make your gums red, tender, and more likely to bleed. This problem, called gingivitis, can often be fixed by brushing and flossing every day.
A more severe form of gum disease, called periodontitis, must be treated by a dentist. If not treated, this infection can lead to sore, bleeding gums, painful chewing problems, and even tooth loss.
To prevent gum disease:
- Brush your teeth twice a day with fluoride toothpaste.
- Floss regularly.
- Visit your dentist routinely for a checkup and cleaning. Tell the dentist about any medical conditions you have and medications you take.
- Eat a well-balanced diet.
- Quit smoking. Smoking increases your risk for gum disease.
