How do our teeth change with age?

Understanding the Effects of Ageing on Oral Health

Our teeth are remarkable structures that endure years of use, from biting and chewing to smiling. However, like the rest of our bodies, they are not immune to the effects of time. As we grow older, both visible and subtle changes can occur, impacting our oral health. Here are some of the most common ways ageing affects our teeth and tips on maintaining a healthy, bright smile.

Enamel Wear and Tear

As we age, our tooth enamel naturally begins to wear down. This process can be accelerated by factors such as chewing, grinding, consuming acidic foods, and brushing too hard. Once enamel is lost, it cannot regenerate, leading to increased sensitivity, discoloration, and vulnerability to decay. To reduce this wear, it's essential to brush gently using a soft-bristled toothbrush, limit acidic foods and drinks, and consult with a dentist about fluoride treatments to strengthen enamel.

Receding Gums

Gum recession is a natural part of aging, where the gum tissue pulls away from the teeth, exposing the roots. This can happen due to various reasons, including overzealous brushing or insufficient brushing. While receding gums may not be an immediate concern, they can make it harder to maintain good oral hygiene, increasing the risk of sensitivity, decay, and gum disease. It’s important to be mindful of these changes and seek professional advice if needed.

Tooth Shifting and Alignment Changes

Ageing can also lead to shifts in tooth alignment. As the dental arches narrow, teeth may become crowded or misaligned, altering their appearance. Additionally, individuals who grind their teeth may notice that their teeth become flatter and shorter over time. This is due to accelerated erosion, often resulting from years of consistent grinding.

Increased Sensitivity

As enamel wears down and gums recede, the more sensitive parts of the teeth become exposed. This can cause discomfort when consuming hot, cold, or sweet foods and drinks. However, some people may experience reduced sensitivity as the nerves inside the teeth shrink with age.

Dry Mouth

Dry mouth is a common issue among older adults, often caused by medications for conditions such as high blood pressure, anxiety, allergies, and pain. Dehydration, certain medical conditions like diabetes, and treatments such as radiotherapy can also contribute to dry mouth. Staying hydrated by sipping water regularly, chewing sugar-free gum to stimulate saliva production, and discussing potential treatments with a dentist can help manage this condition.

Increased Risk of Cavities and Gum Disease

Older adults are more susceptible to cavities and gum disease. This can be attributed to several factors, including gum recession that exposes vulnerable tooth roots, reduced saliva production allowing bacteria to thrive, and difficulty in cleaning teeth properly due to conditions like arthritis. Additionally, older dental restorations may wear out over time and harbor bacteria if not properly maintained. Regular dental check-ups and consistent oral hygiene practices are crucial for preventing these issues.

Brittle Teeth

As we age, the enamel of our teeth can thin, making them more brittle. This is particularly true if combined with dry mouth. Decades of grinding, biting, and consuming acidic foods and drinks can contribute to this brittleness. Individuals who have had root canals or large fillings may also find their teeth becoming more brittle over time.

Recognizing Normal Ageing vs. Early Signs of Oral Disease

It's important to distinguish between normal signs of ageing and early indicators of oral disease. Persistent bad breath, bleeding gums, loose teeth, pain, increased sensitivity, or sores that do not heal within two weeks could signal underlying issues rather than natural ageing. If any of these symptoms are observed, it is essential to consult a dental professional for evaluation.

Preventive Measures for Healthy Oral Habits

Maintaining good oral health should remain a priority as we age. Daily habits such as flossing play a significant role in keeping teeth clean and healthy. Brushing twice a day with fluoride toothpaste and flossing are recommended practices. For those with conditions affecting dexterity, an electric toothbrush can provide an effective clean. Using mouthwash to combat bacteria and brushing the tongue with a toothbrush can further support oral hygiene.
