Aging with Healthy Gums: Why Older Adults Get Gum Disease

Gum disease is very common in older adults, but while there’s a correlation, age itself isn’t the only cause. There’s actually a mix of health changes, habits, and daily challenges that can make gums more vulnerable over time. Continue reading to learn all about these factors, so you can properly prepare to protect your smile and avoid tooth loss at any age.

Cause #1: Plaque Buildup

No matter how old you are, plaque is usually the starting point for gum disease. This sticky film of bacteria forms on your teeth every day when you eat or drink. If it’s not removed with regular brushing and flossing, it hardens into tartar, which can only be removed by a dental professional, like a hygienist or periodontist.

This buildup causes gum inflammation that can lead to gingivitis and, if untreated, periodontitis—a severe form of gum disease that can cause tooth and bone loss.

Cause #2: Health Conditions

Many older adults live with chronic health conditions that affect gum health (whether they realize it or not). Diabetes, heart disease, and autoimmune disorders can all increase the risk of gum disease because they change how your body fights infection.

As a result, your gums may have a harder time healing and staying healthy, even if you otherwise have great oral hygiene.

Cause #3: Age-Related Complications

As people age, brushing and flossing can become more difficult. Arthritis, limited mobility, or vision problems can make it hard to clean their teeth the way they used to. In addition, ill-fitting prosthetics and restorations, like dentures, partials, or bridges, can also trap food and bacteria.

Over time, these mounting challenges can allow gum disease to develop, even in patients who have always cared for their teeth.

Cause #4: Lifestyle Choices

Long-term habits also play a role. Smoking, vaping, heavy alcohol use, and poor nutrition can all increase the risk of gum disease in older adults. For some patients, the effects of decades of tobacco use or inconsistent dental care truly begin to show later in life.

Protecting Your Smile as You Age

Even if you’re experiencing some of these issues, the good news is that gum disease is often preventable. Regular dental checkups and cleanings, using an electric toothbrush, and floss aids like water flossers can help you clean your teeth more effectively as you age.

At the same time, it’s a good idea to coordinate with your physician to help manage any health conditions you might have. Tackling your health from every angle is the best way to ensure you continue to stay healthy well into your golden years.

With a few changes in your lifestyle and the support from your dental team, you can keep your gums healthy and your smile strong!
