Maintaining good oral health becomes increasingly important as we age. For adults over 70, the mouth is closely connected to overall health, and changes associated with ageing, medications and chronic medical conditions can all affect the health of the teeth and gums. Regular dental care not only helps preserve a comfortable, functional smile but also supports general wellbeing, nutrition, and quality of life.
Dry Mouth
One of the most common concerns for older adults is dry mouth. Many medications prescribed for heart disease, high blood pressure, depression and other chronic conditions reduce saliva production. Saliva plays a vital role in protecting teeth by washing away food particles, neutralising acids, and helping prevent decay. Without enough saliva, the risk of tooth decay, gum disease, mouth infections and difficulty swallowing increases significantly. Staying well hydrated, maintaining excellent oral hygiene, and discussing saliva substitutes or other management options with your dentist can help minimise these effects.
Heart Disease
Heart disease and oral health are closely linked. Research has shown an association between gum disease and cardiovascular disease, with chronic inflammation thought to play a contributing role. While gum disease does not directly cause heart disease, untreated periodontal disease can increase inflammation throughout the body. Maintaining healthy gums through regular professional cleans to remove plaque/calculus, thorough brushing/interdental brushes and daily flossing is an important part of supporting overall health.
Arthritis
For many seniors, arthritis can make brushing and flossing difficult. Reduced hand strength, stiffness and pain may mean oral hygiene becomes less effective, allowing plaque to accumulate and increasing the risk of cavities and gum disease. Fortunately, simple adaptations such as electric toothbrushes, modified handles or specialised cleaning aids can make daily oral care much easier. Your dentist can recommend products suited to your individual needs.
Diabetes
Diabetes also has a significant impact on oral health. People with diabetes are more likely to develop gum disease, experience slower healing after dental treatment and have an increased risk of oral infections. In turn, severe gum disease can make blood sugar levels more difficult to control. Keeping diabetes well managed, attending regular dental examinations, and seeking early treatment for any signs of gum disease helps protect both oral and general health.
Osteoporosis
Osteoporosis, which commonly affects older adults, particularly women, may also influence oral health. Although osteoporosis itself does not directly cause tooth loss, the weakening of bone can contribute to changes in the jaw that may affect the stability of teeth and dentures. Some medications used to treat osteoporosis require special consideration before certain dental procedures. Always let your dentist know about your medical history and medications so treatment can be planned safely.
Regular dental visits become even more valuable as we age. Early detection of decay, gum disease, oral cancer and problems with existing fillings, crowns or dentures allows treatment before more complex issues develop. Growing older does not mean accepting poor oral health. With regular dental care, good daily oral hygiene and close communication between your dentist and medical team, adults over 70 can continue to enjoy a healthy smile that supports their overall health, comfort and confidence for years to come.
