Poor oral health is linked to heart disease. A study in Sweden looked at 40- and 50-year-olds to see if self-rated oral health affects heart risk. People with poor oral health had higher rates of unhealthy habits like smoking and bad diet. They also had higher blood pressure and cholesterol levels. The study found that women with poor oral health had a higher risk of heart problems according to a tool called SCORE2. This suggests that people with bad oral health should be checked for heart risks and unhealthy habits to prevent heart issues.
