Summarize the following:
Good dental hygiene can kill the bacteria that might cause aspiration pneumonia. Use a soft-bristled brush to clean the outer and inner surfaces of the teeth. If you use dentures, remove them before brushing. If you’re assisting someone else, stand behind them and off to 1 side. Wear gloves. Peel back their lips with your fingers before brushing the teeth and gums thoroughly. A good mouthwash will kill bacteria in your mouth, even if you don't have teeth. Swish or gargle the mouthwash for 30 seconds before spitting it out in a sink or cup. If desired, add cleaning tablets to the water. When you remove the dentures in the morning, rinse them off with clean water and brush them before putting them in your mouth. Flossing helps remove bacteria between your teeth. Use about 18 inches (46 cm) of floss, and wind the ends around your forefinger and thumb. Slide the floss up between your teeth and down again. If you’re assisting someone else, make sure to wear gloves.  Don’t snap the floss between the teeth. Instead, slowly ease it up and down. If you’re helping another person, standing behind them may help you floss more easily. The dentist can clean your teeth to protect you against bacteria that can cause aspiration pneumonia. They may also do screenings to evaluate your risk of aspiration or your ability to swallow. If you’re a nurse or caretaker, arrange regular dentist visits. If the person is unable to leave their bed or home, see if you can find a dentist who will perform an oral screening at your home.

Summary:
Brush teeth and dentures after every meal. Rinse your mouth with antiseptic mouthwash. Soak dentures in a cup of water overnight to keep them clean. Floss once a day. Visit the dentist at least twice a year.
