Ageing and Your Teeth: Why Older South Africans Need to Take Oral Health More Seriously, Not Less

There is a common but dangerous misconception in South Africa: that losing teeth is an inevitable part of getting older. That dentures are simply what older people have. That after a certain age, your dental battles have been lost.

None of this is true — and holding these beliefs leads to exactly the outcome they predict.

Modern dentistry has the tools to help people keep their natural teeth for a lifetime. But it requires the same thing at every age: regular professional care, effective home hygiene, and the understanding that oral health problems become harder — and more expensive — to treat if ignored.

At Smilez Dental Surgery, we see a growing number of older patients whose dental challenges were shaped by decades of inadequate care or by the genuine barriers older South Africans face in accessing dental services. This article is for them — and for their families.

How Ageing Affects the Mouth

Dry Mouth (Xerostomia)

Dry mouth is the most prevalent oral health problem among older adults, affecting an estimated 30 percent of people over 65. In South Africa, where polypharmacy (taking multiple medications simultaneously) is common in older patients managing chronic conditions, the picture is even more significant — more than 400 commonly prescribed medications list dry mouth as a side effect, including treatments for hypertension, depression, Parkinson's disease, and bladder control.

Saliva is essential for protecting teeth. Without adequate saliva, cavity rates can escalate dramatically — a phenomenon known as rampant or geriatric caries. Teeth that have been cavity-free for decades can begin decaying rapidly when saliva production diminishes.

Root Caries

As gums naturally recede with age, the roots of teeth become exposed. Unlike enamel, tooth roots are covered with cementum — a much softer substance that is far more vulnerable to decay. Root caries develops at the gum line and can progress rapidly, often in areas that are difficult to clean and easy to miss in the mirror.

Gum Disease and Bone Loss

Gum disease is cumulative. Decades of mild, untreated gingivitis can compound into significant periodontitis by older age — with bone loss, loose teeth, and eventual tooth loss if not managed. Systemic conditions common in older patients — diabetes, cardiovascular disease, immune suppression — all exacerbate gum disease.

Oral Cancer

The risk of oral cancer increases significantly with age, with the majority of cases diagnosed in people over 55. Tobacco use, alcohol consumption, and certain viral infections are established risk factors. Annual oral cancer screening at your dental check-up is a straightforward, painless examination that can detect early changes while treatment is far more effective.

Denture-Related Problems

For patients who wear dentures, the jaw changes that occur over time — including ongoing bone resorption — mean that dentures which fitted well at placement become loose, uncomfortable, and less functional over the years. Poorly fitting dentures are not only uncomfortable; they can cause sores, affect nutrition by limiting what the patient can eat, and accelerate bone loss further.

Medication Effects on Oral Health

Beyond dry mouth, several medications have specific oral health implications that older patients and their families should be aware of.

Blood thinners (anticoagulants) such as warfarin affect bleeding during dental procedures. We must know about these medications before any treatment, including professional cleaning.

Bisphosphonates (prescribed for osteoporosis) are associated with a rare but serious condition called medication-related osteonecrosis of the jaw (MRONJ), where the jawbone fails to heal properly after dental extractions or surgery. Any patient taking bisphosphonates must inform their dentist before any surgical dental procedure.

Calcium channel blockers and some anticonvulsants can cause gum overgrowth (gingival hyperplasia), which makes cleaning more difficult and increases gum disease risk.

Maintaining Good Oral Health in Later Life

Adapt Your Tools

If arthritis or reduced dexterity makes brushing difficult, an electric toothbrush is far more effective at removing plaque with minimal technique. Larger-handled toothbrushes, floss holders, and water flossers can also significantly improve cleaning for patients with hand and joint limitations.

Manage Dry Mouth Proactively

Drink water frequently throughout the day. Use alcohol-free mouth rinses. Ask your dentist about fluoride prescription rinses or gels that provide extra protection against cavity formation in the absence of adequate saliva. Saliva substitutes are available for patients with severe dry mouth.

Attend Check-ups More Frequently If Needed

Some older patients benefit from three or four dental visits per year rather than the standard two. The frequency depends on your individual risk profile — how well your systemic conditions are managed, your saliva levels, and the current state of your teeth and gums.

Do Not Dismiss Dental Pain as Normal Ageing

Pain, loose teeth, difficulty chewing, and sores that do not heal are never normal consequences of ageing. They are always signals that something requires attention — and early attention is always preferable to delayed treatment.

Teeth at Every Age

Tooth loss is not inevitable. Dentures are not destiny. With appropriate care, guidance, and professional support, natural teeth can be maintained well into old age — preserving not just function and aesthetics, but the confidence, nutrition, and quality of life that a healthy mouth supports.

If you are an older patient who has been away from the dental chair for a long time, or a family member trying to help an elderly relative access dental care, please reach out to us. We approach every patient with patience, respect, and an understanding of the specific challenges that come with ageing.
