Presidency’s cardiologist warns of heart attack and stroke risks linked to gum inflammation

Seemingly minor gum issues, such as bleeding while brushing or persistent bad breath, may be directly linked to heart attacks, strokes, and high blood pressure. The warning comes from Dr. Ricardo Camarinha, a cardiologist, master in clinical medicine, and specialist in intensive care and aviation medicine, who served for nearly two decades as a physician to the Presidency of the Republic.

“Oral health is directly connected to heart health. When there’s gum inflammation — as in periodontitis — bacteria and toxins can enter the bloodstream and trigger or worsen processes like atherosclerosis,” explains Dr. Camarinha, who is also a lieutenant colonel and creator of the ‘Live More and Better’ health program. “It’s a real risk, but still underrecognized.”

Dr. Camarinha points out that the mouth is the second most microbially diverse area of the body — second only to the gut. When this microbial balance is disrupted, it leads to what doctors call oral dysbiosis, which causes persistent inflammation that can affect the entire cardiovascular system.

“We’re talking about silent inflammation. Someone might be experiencing bleeding gums or bad breath without realizing that, little by little, this could be contributing to serious conditions like high blood pressure or a heart attack,” he warns. “It’s no use treating the heart with advanced technology if we ignore where the inflammation may actually be coming from.”

The topic gained national attention after Ricardo Bueno, former lead singer of the pop group Dominó, was hospitalized with a severe infection originating from a dental problem. The condition progressed to septicemia, sparking renewed concern about oral health as a vital part of whole-body care.

“Cases like Ricardo’s show that this isn’t just theory. It’s something that’s already happening — and it can be prevented with simple, proactive measures,” emphasizes Dr. Camarinha.

According to Dr. Camarinha, individuals with chronic dental infections may face up to five times greater risk of developing high blood pressure. The same applies to serious conditions such as infective endocarditis and heart failure.

“Daily habits like proper tooth brushing, flossing, and regular dental checkups are not just cosmetic routines — they are cardiovascular prevention strategies. Medicine needs to see the body as an integrated system,” he states.

The cardiologist also emphasizes the role of nutrition in this context.

“A diet rich in fiber, vegetables, and probiotics helps maintain a healthy balance in both the oral and gut microbiota, while ultra-processed foods promote chronic inflammation. This is about lifestyle change.”

Dr. Camarinha argues that public health campaigns focused on heart attack and stroke prevention should also include clear guidance on oral hygiene.

“We still don’t talk about this enough. It’s essential to reinforce this connection in health education. Bleeding during brushing isn’t something to ignore — it could be the body warning you of something bigger.”

He concludes with a direct reflection:

“When was the last time you had a dental cleaning? Has your cardiologist ever asked you about your gums? If the answer is no, it’s time to change that perspective. Taking care of your smile is also taking care of your life.”
