A March 2021 study at University College London Eastman Dental Institute found,
"Patients with gum disease often present with elevated blood pressure, especially when there is active gingival inflammation, or bleeding of the gums,"
"Elevated blood pressure is usually asymptomatic, and many individuals may be unaware that they are at increased risk of cardiovascular complications. We aimed to investigate the association between severe periodontitis and high blood pressure in healthy adults without a confirmed diagnosis of hypertension."
“[The] evidence indicates that periodontal bacteria cause damage to the gums and also triggers inflammatory responses that can impact the development of systemic diseases including hypertension,"
"This would mean that the link between gum disease and elevated blood pressure occurs well before a patient develops high blood pressure. Our study also confirms that a worryingly high number of individuals are unaware of a possible diagnosis of hypertension."
"Integration of hypertension screening by dental professionals with referrals to primary care professionals and periodontal disease screening by medical professionals with referrals to periodontists could improve detection and treatment of both conditions to improve oral health and reduce the burden of hypertension and its complications. Oral health strategies such as brushing teeth twice daily are proven to be very effective in managing and preventing the most common oral conditions, and our study's results indicate they can also be a powerful and affordable tool to help prevent hypertension."
