Dental infections left untreated can enter the bloodstream and trigger severe cardiac complications including endocarditis, according to a joint warning issued by the Spanish General Council of Dentists and the Spanish Dental Foundation ahead of World Heart Day.
These pathologies generate more than 5 million hospital stays annually and incur direct healthcare costs exceeding 9.000 millones de euros per year, representing more than 7 percent of Spain's national health expenditure.
Oral Bacteria and Cardiac Risk
The close relationship between oral health and cardiovascular function stems from how bacteria from dental infections migrate. When oral conditions like periodontitis or untreated cavities progress, oral pathogens cross into the bloodstream and reach the heart valves. This bacterial invasion causes endocarditis, an infection of the heart valves, while worsening the prevalence and prognosis of broader cardiovascular diseases.
The Spanish General Council of Dentists and the Spanish Dental Foundation emphasize that dentists play a key role in cardiovascular prevention and the ongoing management of cardiac patients. Routine dental exams and early treatment of oral infections stop oral bacteria from entering systemic circulation.
Upcoming Oral Health and Heart Campaign
To combat these statistics, the dental institutions are preparing the launch of the “Oral Health and Heart Campaign” under the slogan “Take care of your mouth, protect your heart.” The initiative targets both the general public and dental professionals through distinct digital resources.
A dedicated microsite will go live on November 2, offering downloadable informational brochures, infographics, a combined manual on oral and cardiac health, a decálogo of guidelines, and explanatory videos. Simultaneously, the organizations are designing a specialized mobile application for dentists to review cardiovascular events linked to oral health and clinical recommendations for treating heart patients. Dentists enrolled in the campaign by October 19 will receive a comprehensive Clinical Guide on Oral and Cardiovascular Health in November.
Link between dental infections and heart disease
How does dental health affect the heart?
Bacteria from untreated dental infections can enter the bloodstream and travel to the heart, causing endocarditis and other serious cardiovascular complications. Scientific evidence demonstrates a clear link between oral health status and both the prevalence and prognosis of heart disease.
What specific heart conditions are linked to poor dental health?
Untreated dental issues can lead to bacterial endocarditis, which is an infection of the heart valves. Dental professionals note that managing oral health is an essential component of cardiovascular prevention and the clinical care of cardiac patients.
How can patients protect their heart through oral care?
Specialists recommend maintaining rigorous oral hygiene, addressing dental infections promptly, and scheduling regular dental visits. Treating conditions such as periodontitis and caries early prevents bacteria from entering the bloodstream and threatening cardiovascular health.
