While the overall connection between oral health and overall health is well documented.
It’s not generally discussed at well or dental visits.
One secret to preventing dementia, diabetes, and heart disease may lie in your oral health habits. Here’s the dental routine to follow
While the connection between oral health and general health is well documented, it’s not generally discussed at well or dental visits. It should be: An April 2022 report from The National Institutes of Health found that 90% of adults ages 20 to 64 experience tooth decay, while almost 50% of adults 45 to 64 have gum disease.
Dr. Michael Roizen, chief wellness officer at Cleveland Clinic, says oral diseases have a large association with overall health. Research has shown that there’s an association between your dental health habits and whether or not you develop diabetes, Alzheimer’s, stroke, or heart disease.
When we don’t take care of our oral health, says Roizen, dental caries (tooth decay) and gum disease can enter the bloodstream, contributing to plaque disruption in the arteries, or promoting inflammation in the brain and other areas of the body. “Flossing your teeth is the equivalent of 8,000 steps a day,” says Roizen. “Which is pretty darn powerful.”
Think of the body as a human donut
In 2019, the World Health Organization named tooth decay in permanent teeth as the most common health condition in its Global Burden of Disease report. Oral diseases affect about 3.5 billion people worldwide
What we often don’t realize is that this isn’t bad just for our mouths, but our bodies. “People think of their heads and teeth as disconnected from the rest of their bodies, but they’re not,” says Dr. Maria Ryan, DDS, Ph.D. in oral biology and chief clinical officer at Colgate-Palmolive Company. Viewing the body as one connected system helps reinforce how it can influence all areas of wellness and the importance of maintaining good oral hygiene, says Ryan.

Naveem Jain, founder of Viome, a company that builds personalized toothpaste and supplements based on a person’s microbiome, compares the human body to a donut. “There is a tube that goes through us,” says Jain, noting that billions of microbes enter the body through that tube as we breathe. “When the protective barrier is broken, you have system inflammation in the body. If you have a leaky gum, it’s the same concept. If our heart is bleeding or even our fingers, we’d be trying to figure it out. If our gums are bleeding, eh whatever. In both cases, all of your microbes have a free path into the bloodstream.”
That path is where trouble starts, says Ryan. It’s no surprise then that in one study, published in Hypertension, an American Heart Association journal, found that people with gum disease were twice as likely to have a heart attack and three times as likely to have a stroke than those without inflammatory gum disease. “People think, ‘What’s the worst thing that can happen? I can lose a tooth,’” says Ryan. “Well, it could be worse than that.”
Poor oral health can also impact our confidence
If the prospect of developing heart disease or diabetes isn’t enough to get you to the dentist, maybe the idea of looking good will. After all, dental hygiene is also front and center in all of our human interactions. If you’re self-conscious about bad breath or missing teeth, it might affect your ability to move through the world with confidence. “That can impact someone’s ability to get a job, or their relationships,” says Ryan. “It’s important on so many levels.”
And weak teeth can impact the way you’re able to address more mundane aspects of your health. Ryan uses the example of a healthy diet. If a physician recommends eating more fruits and vegetables to a patient with poor oral health, the patient may feel stuck eating foods such as apples, carrots, and broccoli if missing teeth and cavities are a factor, Ryan says.
When all of these factors impede a person’s ability to be social and engaged on a personal level, their mental health can suffer. One 2022 study documented the connection between poor oral health and increased anxiety and depression.
A big part of addressing the oral health crisis is prevention and education, says Ryan who leads Colgate-Palmolive’s five-year, $100 million Know Your OQ (oral health quotient). It aims to shift some of these statistics and increase awareness on the importance of simple and consistent oral hygiene.
How to protect your oral health and overall well-being
The American Dental Association and WHO recommend six basic steps for preventing gum disease:
- Brush twice a day for two minutes
- Floss once a day.
- See your dentist every six months.
- Limit sugary drinks and snacks.
- Avoid all forms of tobacco
- Use protective equipment during sports
It might seem like really basic information, says Ryan, but if everyone was doing it the stats on oral health wouldn’t be what they are.
Dr. Tien Jiang, a practicing dentist who teaches oral health policy and epidemiology at Harvard School of Dental Medicine, says she takes every opportunity she can to weave education into her interactions with patients so her approach is more preventative than reactive whenever it can be. “Just like high blood pressure, with a lot of dental diseases or concerns—for instance, an early cavity—you can’t feel anything,” says Jiang. “You might not feel anything until it’s advanced. You can have a patient come in and a dentist diagnoses five cavities and they’ve been feeling fine.”
But at that point, the situation has turned urgent and the patient is in tremendous pain—especially in the case of periodontal disease, says Jiang. To add insult to injury the patient now also faces a steep dental bill to cover care and save the tooth. “We have an uphill battle,” she says. “We want to diagnose but there’s always a suspicion that the dentist just wants to make money.”
From Ryan’s perspective, this makes education and normalization of these ideas critical to shift the trajectory of how we frame and prioritize our oral health.
Relatedly, she says, knowing where to get dental care could also be a barrier. Aside from dental practices, dental schools offer cleanings, as well as federally qualified health centers (FQHC). “Not just preventative strategies, but also the signs and symptoms so if they have disease they go and get it managed. There are so many places to get care.”

Tooth loss in older adults linked to higher risk of dementia
Alzheimer’s Disease Chronic Conditions Cognitive Health Dementias
Older adults with tooth loss have a higher risk of cognitive impairment and dementia, with increasing risk with each missing tooth, according to a new study published in the Journal of the American Medical Directors Association.
Problems with oral health, such as poor oral hygiene, tooth cavities, gum disease, and tooth loss, are more common in older adults than in other age groups. Older adults are also more likely to have cognitive impairment or dementia, and recent studies have suggested a link between oral health and these conditions. To get a comprehensive picture of this association, NIA-supported researchers led by a team at New York University analyzed results from several long-term studies on the link between tooth loss and the risk of cognitive impairment.
The researchers conducted a detailed search of six major databases of biomedical science publications and identified 14 relevant studies. These studies used questionnaires, assessments, medical records, and information from death certificates to identify participants with cognitive impairment or dementia. Out of a total of 34,074 participants, 4,689 had cognitive impairment or dementia. The studies used medical examinations and self-reported records to assess tooth loss and classified participants as having more or fewer missing teeth.
The researchers found that participants with more missing teeth had, on average, a 48% higher risk of cognitive impairment and a 28% higher risk of dementia. The relationship between tooth loss and cognitive decline was “dose-dependent”: Each lost tooth was associated with a 1.4% increase in the risk of cognitive impairment and a 1.1% increase in the risk of dementia. Participants who were missing 20 or more teeth had a 31% higher risk of cognitive impairment. Participants who had lost all their teeth had a 54% higher risk of cognitive impairment and a 40% higher risk of dementia. Interestingly, participants who had missing teeth but used dentures did not have a significantly higher risk of dementia than participants without missing teeth.
The researchers note that the reason for this association between tooth loss and the risk of cognitive decline is unclear. Still, tooth loss can result in problems with chewing that might lead to nutritional deficiencies, chemical imbalances, or changes to the brain that affect brain function. Also, poor oral hygiene might lead to increased bacteria in the mouth and to gum disease, which can cause inflammation and raise the risk of beta-amyloid plaques in the brain, leading to dementia. Tooth loss without the use of dentures might also be an indication of lower socioeconomic status and lower education level, both of which are independently linked to an increased risk of dementia. Alternatively, missing teeth might be an early sign of cognitive impairment: People with cognitive decline might be less likely to keep up with oral hygiene, leading to tooth loss.
The research was limited by the fact that the various publications studied used different methods of data collection and data analysis. However, the results suggest that timely interventions, such as encouraging the use of dentures and other orthodontic treatments and large-scale education programs on the importance of oral hygiene in older adults, might help prevent or slow down cognitive decline linked to tooth loss.
This research was funded in part by NIA grant R56AG067619.
