When people think about steps we can take to live healthier lives, most of us think about a healthy diet, exercise, and sleep. But did you know that brushing and flossing can also have a significant impact on your overall health?
A new survey showed that only 12% of US adults ranked oral health among their top three health habits, but taking care of your teeth and gums affects more than just your mouth.
In fact, issues with your teeth and gums can be early signs of other health problems, and healthy oral habits can have benefits that extend far beyond your smile.
Your oral health is part of your overall health
Gum disease is caused by harmful bacteria building up in the mouth. That, in turn, is linked to several serious health conditions, including heart disease, diabetes, Alzheimer's disease, and even infertility.
The connection between your mouth and your body
Your mouth can provide early signs of changes in your overall health. Symptoms such as bleeding gums or sores that do not heal may point to inflammation or other health concerns in other areas of your body.
During a routine visit, your family physician may ask about your oral health because it can offer important clues about your overall health. We look at the whole picture, including things like your chronic diseases, changes in your body and risk factors so we can help you stay healthy.
Healthy gums can help support a healthy heart
Research has found links between gum disease and cardiovascular problems, including heart attack, stroke and blocked arteries.
Gum disease causes inflammation in your mouth, and that inflammation may spread into your bloodstream. Early gum disease may cause swollen, tender gums or persistent bad breath. As the condition progresses, it can damage the tissues and bone that support your teeth.
Though taking care of your gums is just one step in preventing heart disease, keeping your mouth healthy supports your overall health.
Diabetes and oral health impact each other
Diabetes and gum disease both play a role in the other disease.
People with diabetes are more likely to develop gum disease and may have a harder time healing from infections. At the same time, untreated gum disease can make it more difficult to manage blood sugar levels. In other words, treating one condition has a benefit for both diseases.
If you have diabetes, maintaining good oral hygiene and seeing your dentist regularly should be an important part of your care plan.
Don't ignore changes in your mouth
Many people dismiss symptoms like bleeding gums or dry mouth because they might not seem serious. But they may be the first signs of system-wide illness.
Talk with your doctor or dentist if you notice:
- Bleeding gums
- Dry mouth
- Mouth sores
- Mouth pain
- Frequent infections
You should seek medical or dental care if you have gums that continue to bleed, mouth sores that last longer than two weeks, dry mouth that doesn't improve, painful or loose teeth, swelling in your mouth, or trouble chewing or swallowing.
Getting these symptoms checked early can help identify problems before they become more serious.
Simple habits can make a big difference
The good news is that protecting your oral health doesn't require complicated routines.
A few simple daily habits can have a lasting impact:
- Brush your teeth twice a day for two minutes using fluoride toothpaste.
- Floss every day to remove plaque between your teeth.
- Visit your dentist regularly for preventive care.
- Avoid tobacco products.
- Manage chronic health conditions such as diabetes.
- Tell your doctor or dentist about any changes you notice in your mouth.
Life gets busy. It’s easy to fall behind on oral care when we’re tired, stressed or our routines are disrupted. Those are some of the most common reasons people give for falling behind on oral care. But even on busy days, taking just a few minutes to brush and floss is an investment in your long-term health.
A healthier mouth, a healthier you
Good oral health is about much more than preventing cavities. It's about supporting your heart, helping manage chronic diseases, catching potential problems early and improving your overall quality of life.
Healthy teeth and gums help you eat comfortably, speak confidently and smile without hesitation. They can also contribute to better well-being, greater confidence and, for children, even better mental health.
Small daily habits really do add up. By making oral health part of your overall wellness routine, you're taking an important step toward protecting your health for years to come.
After all, one of the healthiest things you can do for your body may start with taking care of your smile.
