Which of the following is crucial for the prevention of periodontal disease?

Regular home oral hygiene practices are essential for the prevention of periodontal disease because they help in maintaining the health of the gums and teeth on a daily basis. This includes brushing teeth at least twice a day and using fluoride toothpaste, along with effective flossing to remove plaque and food particles from between teeth and along the gum line.

While professional cleanings are important for maintaining oral health, they usually occur every six months, and thus cannot solely prevent periodontal disease. Eliminating all sugars from the diet might reduce the risk of cavities, but it is not the primary preventive measure against periodontal disease. Lastly, routine flossing alone, without comprehensive home care practices such as brushing, may not be sufficient to effectively prevent periodontal disease. Overall, a combination of regular home oral hygiene practices is the most effective approach for reducing the risk of gum disease.
