Most people know that regular teeth cleanings are essential for a healthy smile, but fewer realize their impact on overall well-being. While the primary goal of biannual dental visits is to prevent cavities and gum disease, these checkups also play a key role in maintaining whole-body health. From reducing the risk of heart disease to supporting preventive care, here’s how good oral hygiene benefits more than just your mouth.
Cardiovascular Disease
For years, doctors and dentists have recognized a strong link between oral health and cardiac health. Numerous studies point to the fact that individuals with poor oral health, specifically gum disease, have higher rates of heart attack and stroke. A 2018 study of 65,000 cardiovascular events found a moderate correlation between tooth loss and coronary heart disease.
The leading theory connecting oral health and cardiovascular disease is related to bacteria infecting gums, leading to gingivitis and periodontitis. This bacteria can travel to blood vessels, causing inflammation and small blood clots, leading to heart attack or stroke. The theory has been supported by the discovery of remnants of oral bacteria within blood vessels located far from the mouth.
Endocarditis, an infection of the heart chamber’s inner lining, has also been connected to poor oral health. This can happen when bacteria or other germs spread to the bloodstream and attach to certain areas in the heart.
Alzheimer’s Disease & Dementia
A recent study by the National Institute on Aging (NIA) has connected periodontal disease to the development of Alzheimer’s Disease and vascular dementia. As reported in the Journal of Alzheimer’s Disease, periodontitis is characterized by “bad bacteria,” teeth degradation, increased pocket depths, inflammation, and bone loss. The associated bacteria travels through the bloodstream to the brain, suggesting this sequence of events can lead to dementia.
NIA experts examined whether the bacteria associated with periodontal infections were linked to dementia diagnoses and deaths, and confirmed that older adults with signs of periodontitis were more likely to develop Alzheimer’s during the study period. The study compared different age groups of 6,000 total patients with up to 26 years of follow-up.
Respiratory Disease
The mouth is the central entry point for bacteria and viruses to enter the body, putting the lungs and bronchi at increased risk considering their proximity to the mouth. If bacteria is present in the mouth due to poor oral hygiene, it can be aspirated into the lungs and lead to certain respiratory diseases. Studies have shown that chronic periodontitis and oral bacteria are associated with the onset and progression of pneumonia, influenza, and chronic obstructive pulmonary disease.
Lifestyle
A strong correlation has also been made between oral health and an overall healthy lifestyle. Those who are consistent with teeth cleanings and prioritize oral health often tend to live active lifestyles, prioritize nutrition, take vitamins, maintain a healthy weight, and are non-smokers. A healthy lifestyle without tobacco product use is a significant factor, considering the strong connection between tobacco and gum disease. These individuals also have reduced sugar intake due to their focus on nutrition, which helps to prevent cavities.
Preventive Care
Regular dental checkups, including biannual cleanings, play a crucial role in identifying oral health concerns before they develop into serious issues. With the help of dental X-rays and thorough visual exams, dentists can detect early signs of potential problems and intervene before they lead to costly, uncomfortable treatments. Prioritizing preventive care also supports long-term health by reducing the risk of serious conditions linked to poor oral hygiene.
Your immune system works hard to protect you from illness, and maintaining good oral hygiene gives it the support it needs. Brushing and flossing twice a day, using mouthwash to eliminate lingering particles, limiting sugar intake, avoiding tobacco products, and scheduling routine cleanings all contribute to a healthier mouth—and a healthier you.
