Gum Disease in Older Adults: Signs, Risks, and Treatment

Gum disease is one of the most common and most underestimated dental problems facing older adults. Studies suggest that more than 70% of adults over 65 have some form of gum disease — but because it often develops slowly and painlessly, many people don’t know they have it until it’s already advanced.

What Is Gum Disease?

Gum disease, also called periodontal disease, is a bacterial infection of the tissues that support your teeth. It starts as gingivitis — inflammation of the gums caused by plaque buildup near the gumline. If gingivitis is left untreated, it can progress to periodontitis, where the infection spreads below the gumline, damages the bone and connective tissue, and eventually leads to tooth loss.

Warning Signs to Watch For

Gums that bleed when you brush or floss are one of the earliest signs — and one of the most commonly ignored. People assume it’s normal, but healthy gums don’t bleed. Red, swollen, or puffy gums are another indicator. Bad breath that doesn’t go away with brushing, teeth that feel loose, or gums that appear to be pulling away from the teeth (making teeth look longer) are all signs of more advanced gum disease. If you notice any of these, it’s time to see a dentist.

Why Older Adults Are at Higher Risk

Several factors make seniors more vulnerable. Years of accumulated plaque and tartar take a toll. Dry mouth (often caused by medications) removes saliva’s protective effect, allowing bacteria to multiply faster. Systemic conditions like diabetes impair the body’s ability to fight infection, including gum infection. Difficulty maintaining thorough oral hygiene — due to arthritis, limited mobility, or cognitive decline — allows plaque to build up more easily.

The Systemic Connection

Gum disease isn’t just a mouth problem. Research has established strong links between periodontal disease and serious systemic conditions including heart disease, diabetes, pneumonia, and stroke. The bacteria from infected gums can enter the bloodstream and contribute to inflammation throughout the body. Treating gum disease is part of managing overall health — not just dental health.

How It’s Treated

The good news is that gum disease is treatable, and even advanced cases can be managed effectively. The primary treatment is a deep cleaning called scaling and root planing, which removes bacteria and tartar from below the gumline. This can be done in a mobile dental setting. Antibiotic treatment is sometimes used alongside the deep cleaning. Maintaining regular cleanings — every three to four months for patients with gum disease — is essential to keeping it under control.
