Poor oral hygiene can lead to periodontal disease in over 75% of Americans and increase risks for other health issues. Multiple problems arise from neglecting dental hygiene, including gingivitis, periodontitis, and increased risk of heart disease. Maintaining good oral hygiene through brushing, flossing, using mouthwash, and regular dental checkups every 6 months can prevent these issues by disrupting bacteria that can enter the bloodstream and cause disease. The key is practicing good dental hygiene routines.
