Gum Disease and Whole Body Health

Periodontitis is a chronic inflammatory disease of the tissue and bone that hold teeth in place. It affects a large share of adults over 30 and becomes more common with age. It is usually painless until it is advanced, which is why so many people are surprised by the diagnosis.

How it develops

Bacterial plaque collects at the gum line. If it is not removed, the gum becomes inflamed, which is gingivitis: red, puffy gums that bleed when brushed. Gingivitis is reversible with good cleaning.

In some people the inflammation continues and moves deeper, forming pockets between tooth and gum. Bone is lost. Teeth loosen. That stage is periodontitis, and the bone does not grow back on its own. Smoking, uncontrolled diabetes, genetics, certain medications, and dry mouth all raise the risk.

The links to the rest of the body

Periodontitis creates a large chronically inflamed surface with direct access to the bloodstream. Researchers have studied whether that matters elsewhere. The state of the evidence, stated carefully:

• Diabetes. This is the strongest link, and it runs both ways. Poorly controlled diabetes worsens gum disease, and treating gum disease produces a small but measurable improvement in blood sugar control in randomized trials. Major diabetes and dental organizations both acknowledge this.
• Cardiovascular disease. Consistent associations exist between periodontitis and heart disease and stroke. What has not been shown is that treating gum disease prevents heart attacks. The American Heart Association has stated that the relationship is an association, not proven cause. Shared risk factors such as smoking explain part of it.
• Pregnancy outcomes. Gum disease is associated with preterm birth and low birth weight. Trials of periodontal treatment during pregnancy have not reliably improved those outcomes, though treatment during pregnancy is safe and recommended for the mother's own health.
• Respiratory infection. Oral bacteria can be aspirated into the lungs. Oral care programs reduce pneumonia in nursing home residents, which is one of the more practical findings in this field.
• Rheumatoid arthritis and cognitive decline. Associations are reported and mechanisms are proposed. Causation is not established. Treat headlines here with caution.

Warning signs

See a dentist if you notice bleeding when you brush or floss, gums that are red or swollen, persistent bad breath or a bad taste, gums pulling back from the teeth, teeth that feel loose or have shifted, or a change in how your bite fits together.

Prevention and treatment

Brush twice daily with fluoride toothpaste, clean between the teeth every day with floss or interdental brushes, and see a dentist and hygienist regularly. Stop smoking. Manage diabetes. That covers most of the risk you control.

Established periodontitis is treated by dental professionals with scaling and root planing, sometimes antimicrobials, and in advanced cases surgery. This is a dentist's and periodontist's field, not a medical spa's, and anyone telling you otherwise is outside their scope.

Oral health also shapes the lower face over time. Tooth loss and bone resorption in the jaw change facial proportions in ways that no cosmetic treatment corrects well. That is one reason a good clinician offering skin care in Knoxville will ask about your dental history before discussing the lower face, and will refer you to a dentist when that is the right answer.
