Presented by Dental Care Delray
Maintaining a healthy mouth isn’t just about having fresh breath or a beautiful smile — it’s a critical part of protecting your overall health. Researchers have increasingly discovered that the bacteria living in your mouth can play a major role in various systemic diseases throughout the body. At Dental Care Delray, we believe in educating our patients about how oral health impacts their entire well-being.
In this blog post, we’ll explore the different types of bacteria in the mouth and their connection to diseases such as heart disease, diabetes, respiratory infections, and even cognitive decline.
The Oral Microbiome: A Delicate Balance
Your mouth is home to over 700 species of bacteria, both beneficial and harmful. A balanced oral microbiome helps maintain healthy teeth and gums, while an overgrowth of harmful bacteria can lead to gum disease, tooth decay, and more serious complications. This imbalance, known as dysbiosis, is the root of many oral and systemic health problems.
Common Harmful Bacteria Found in the Mouth
1. Porphyromonas gingivalis
- Found in advanced periodontal (gum) disease
- Produces enzymes that destroy gum tissue and bone
- Associated with cardiovascular disease and Alzheimer’s
2. Fusobacterium nucleatum
- Contributes to gum inflammation and periodontitis
- Found in higher levels in colorectal cancer tissue
- Can enter the bloodstream and spread systemically
3. Treponema denticola
- Works synergistically with P. gingivalis
- Involved in tissue destruction and chronic inflammation
- Linked to heart disease and neurological conditions
4. Streptococcus mutans
- Major contributor to dental cavities
- Produces acid that erodes tooth enamel
- Potential to enter bloodstream during brushing/flossing with gum disease present
How Oral Bacteria Affect Systemic Health
Once harmful oral bacteria breach the gum tissue, they can enter the bloodstream and travel throughout the body, triggering inflammation and immune responses in other organs. Here are a few conditions linked to oral bacteria:
- Heart Disease: Oral bacteria can cause inflammation in blood vessels and contribute to plaque buildup, increasing the risk of heart attacks and strokes.
- Diabetes: Gum disease can make it more difficult to regulate blood sugar levels, creating a two-way relationship between diabetes and oral health.
- Respiratory Infections: Bacteria from the mouth can be inhaled into the lungs, increasing the risk of pneumonia and other respiratory diseases.
- Alzheimer’s Disease: Studies have found P. gingivalis and its toxins in the brains of Alzheimer’s patients.
- Adverse Pregnancy Outcomes: Oral bacteria have been linked to preterm birth and low birth weight.
Protecting Your Health Through Better Oral Hygiene
At Dental Care Delray, we recommend the following practices to protect both your oral and systemic health:
- Brush twice a day with fluoride toothpaste
- Floss daily to remove bacteria between teeth
- Use antibacterial mouthwash as advised
- Schedule regular cleanings and exams
- Treat gum disease promptly
- Eat a healthy diet low in sugar and processed foods
Q&A: Oral Bacteria and Systemic Disease
Q: Can brushing and flossing really protect my heart?
A: Yes! By reducing harmful oral bacteria and preventing gum disease, you lower the risk of inflammation that could affect your heart and blood vessels.
Q: How do I know if I have harmful bacteria in my mouth?
A: Symptoms like chronic bad breath, bleeding gums, receding gums, and loose teeth may indicate an overgrowth of harmful bacteria. A dental exam and periodontal screening can provide a clearer picture.
Q: Are probiotics helpful for oral health?
A: Emerging research suggests that certain probiotics may support a healthy oral microbiome, but they are best used alongside traditional oral hygiene practices — not as a replacement.
Q: If I have diabetes, should I be more concerned about gum disease?
A: Absolutely. Gum disease can make it harder to control blood sugar, and uncontrolled diabetes can worsen gum disease — creating a harmful cycle.
Q: Is there a connection between oral bacteria and cancer?
A: Some studies have linked specific bacteria like Fusobacterium nucleatum to increased cancer risk, particularly colorectal cancer, but more research is needed.
