Final answer:
Periodontal disease has been linked to an increased risk of cardiovascular disease, due to bacteria from oral infections entering the bloodstream and contributing to artery plaque buildup.
Step-by-step explanation:
According to recent studies, periodontal disease is associated with an increased risk of developing cardiovascular disease. This occurs because the bacteria responsible for periodontal disease, such as Streptococcus mutans, can enter the bloodstream during activities like tooth brushing or dental procedures. Once in the bloodstream, these bacteria can cause inflammation leading to plaque accumulation in the arteries, which is associated with atherosclerosis, heart attacks, and strokes, all of which are cardiovascular conditions.
