The Importance of a Healthy Mouth for a Healthy Body

In America, dental health is often treated as something totally separate from the rest of your body. But the mouth is connected to the digestive tract, which is one of the most critical systems we have. An overgrowth of bacteria in your gums not only means you have periodontal disease, it also means you are constantly swallowing these germs and introducing them to the rest of your body.

Keep reading to explore the mouth-body connection, how oral health and overall health are related, and how improving your dental care can help you achieve better wellness.

Did You Know?

The Mayo Clinic confirms that harmful bacteria from infections in the gums and teeth can travel through the bloodstream, affecting organs and tissues throughout your body.

Breaking the Mouth-Body Connection Down

Lyme Disease

Lyme disease is a chronic condition caused by a bite from a tick with the Borrelia burgdorferi bacteria. This can result in widespread inflammation in the body, facial pain, sensitive teeth, and even bad breath. For patients with suspected or confirmed Lyme disease, we may recommend:

At Green Dentistry, we take a special approach to Lyme disease and its connection to oral health and the rest of the body, so you can live your best life despite the condition.

Heart Attacks, Diabetes & Cancer Therapy

One major component of the mouth-body connection is that poor oral health can also be a precursor to cardiovascular disease or increase the risk of diabetes complications, especially in those with pre-existing medical conditions.

  • Oral bacteria can contribute to the formation of blood clots and arterial plaque or cause the lining of the heart to become infected. This makes patients more likely to experience a stroke or heart attack.
  • Gum disease can also make blood glucose harder to manage in diabetic people. Then, when high sugar levels worsen the overgrowth of bacteria in the mouth, the problem continues.
  • Cancer treatments, including chemotherapy and radiation, can weaken the immune system and make patients more susceptible to dental problems.

Alzheimer’s Disease

Not only does harmful bacteria from infected gums travel through the cardiovascular system to the heart, it can also disrupt the blood-brain barrier. This allows the bacteria to attack brain tissue and cause cognitive decline.

  • Periodontal infections accelerate the development of amyloid plaques associated with Alzheimer’s disease.
  • Seniors with untreated gingivitis are more likely to develop Alzheimer’s, according to the Journal of Alzheimer’s Disease.
  • Memory loss and dementia can make oral hygiene harder, creating a cycle that perpetuates itself.

Hormones & Pregnancy

Individuals experiencing hormonal changes also have an increased risk of periodontal infections, gum recession, and tooth loss. This is because hormones like estrogen and progesterone change the way blood flows to your gums and reduce the production of saliva. Both of these contribute to the buildup of oral bacteria that can progress to gingivitis if not treated.

Hormonal conditions that impact dental health include:

  • Pregnancy
  • Gestational diabetes
  • Menopause
  • Hormone replacement therapy (HRT)
  • Oral contraceptives (birth control)
  • Polycystic ovary syndrome (PCOS)
  • Hyper/hypothyroidism
  • Addison’s Disease and Cushing’s Syndrome

Acid Reflux, Gut Dysbiosis, IBS, Anxiety/Depression & ADHD

Your oral health and overall health also relate to many other conditions, including:

  • Acid reflux. This condition is characterized by the regurgitation of stomach acid and contents into the esophagus. It can erode tooth enamel and make it harder to fight harmful oral bacteria.
  • Gut dysbiosis. This condition occurs when there are too many bad bacteria in the gut and not enough good ones. Dysbiosis can be exacerbated by gum disease and vice versa.
  • Irritable bowel syndrome (IBS). This is a condition that can cause abdominal discomfort, bloating, constipation, and other challenging digestive issues. These symptoms are the result of chronic inflammation that can also affect your gums.
  • Anxiety and depression. Medications used to treat mental health conditions can cause dry mouth, while the conditions themselves can make it harder for people to maintain good oral hygiene.
  • Attention Deficit Hyperactivity Disorder (ADHD). This condition can be caused by improperly developed sinuses and relaxed tongue muscles. Not only can ADHD make it harder for people to remember to brush their teeth, it can also lead to the development of obstructive sleep apnea.

Autoimmune Disorders & Respiratory Diseases

The mouth-body connection also includes a meaningful relationship between oral hygiene, autoimmune disorders, and respiratory health conditions:

  • Inflammation caused by autoimmune dysfunction like lupus or rheumatoid arthritis can also cause inflammation in the gums. Plus, an overactive immune system often can’t tell the difference between healthy cells and bacteria. The result is an immune response that makes you feel sick, but doesn’t do much in the way of actually getting rid of harmful microorganisms.
  • Emerging research suggests that an overgrowth of bacteria in the mouth may reach the lungs, especially for patients who are in the hospital and undergoing mechanical ventilation. These studies indicate that as oral bacteria is aspirated into the lungs when breathing, conditions like pneumonia can develop or chronic issues like asthma can worsen.

Bruxism, Headaches & Arthritis

Other conditions that relate back to the mouth-body connection and oral health and overall health include headaches and arthritis. While your first thought might not be that your mouth is causing these issues, this may very well be the case. Here’s what to know:

  • Bruxism occurs when a person grinds their teeth at night, or sometimes during the day. This can be caused by things like stress, oral bacteria, and tooth misalignment.
  • Headaches are a common side effect of bruxism and may also be a sign of temporomandibular joint disorder (TMJ/TMD). Patients may also feel tension in their necks and shoulders.
  • The pain of arthritis can be worsened by gingival bacteria that make their way to a person’s bloodstream. Once this happens, the joints become more inflamed and uncomfortable.

Good oral hygiene, regular dental visits, and wearing a mouth guard to protect your teeth from grinding at night can help.
