Proper dental hygiene helps you prevent gum disease. Brush your teeth after meals to remove food debris and plaque, floss your teeth at least once per day, and swish with mouthwash regularly to get remove food particle missing by brushing and flossing. It's also important to know and understand your risks when it comes to gum disease. If you smoke or fail to maintain a healthy diet, you have a higher risk of getting gum disease, so you should discuss your options with your dentist. Also, talk to your dentist about your family's history of gum disease, because your genetics may put you at a higher risk.
