Is it possible to prevent gum disease?

Besides these basic oral hygiene practices, there are other things that can be done to eliminate the factors that lead to an increase in gum disease:

• Sleep/stress: The immune system is very important in controlling disease, and getting adequate sleep and reducing stress will help the body fight gum disease, too.
• Stop smoking: Smokers are much more likely to develop gingivitis and periodontitis. Avoiding tobacco should be a primary goal to achieve healthy gums.
• Orthodontic therapy or braces: It is much easier to remove plaque from straight teeth than crowded, overlapped, and crooked teeth. Braces can make a big difference in having healthier gums.
• Diet: Limiting the frequency of plaque-causing sugars and carbohydrates will help limit plaque. Eating a well-balanced diet will help keep the body’s immune system healthy and ready to fight infection.
