How do dental needs change as we get older?

A guide for older adults and for people helping a parent look after their teeth.

Dr Bill Kalis — Saturday 14 November 2026

As we get older, the main dental changes are a drier mouth, more wear on teeth and old fillings, a higher risk of gum disease and decay at the gum line, and dentures that no longer fit. Most of these can be managed well if they are picked up early.

I am Dr Bill Kalis, principal dentist at Padstow Dental in Padstow, Sydney. Many of my patients have been with the practice for decades, and I also see adult children helping a parent with their dental care.

Why does dry mouth matter?

Saliva protects teeth. Many common medications reduce it, including some for blood pressure, depression, allergies and bladder control. A dry mouth makes decay much more likely, especially along the gum line and around old fillings and crowns.

What helps: sipping water often, sugar-free gum, high-fluoride toothpaste where we recommend it, and more frequent professional cleans.

What happens to old fillings and crowns?

They wear out. Fillings placed decades ago can crack or leak, and the tooth around them can break. Regular examinations pick this up before a tooth fractures.

Why are the gums more of a concern?

Gums recede with age, exposing the root surface, which decays more easily than enamel. Gum disease is also linked with general health conditions such as diabetes. Our oral health therapists provide regular cleans and can adapt home care for hands that are less nimble.

What if dentures are loose?

Dentures loosen because the jawbone shrinks over time. A reline can help. For a lower denture that will not stay put, implant-retained dentures are an option for suitable patients.

Is it too late to replace missing teeth?

Age alone is not a barrier to implants or other treatment. General health, medications and bone matter more. Read about dental implants at Padstow Dental.

How can I help a parent with their dental care?

• Come to the appointment if they would like you there

• Bring a current list of their medications

• Tell us about memory, mobility or swallowing difficulties

• Ask us to write instructions down

• Check that dentures are cleaned daily and taken out at night

• Look for signs of trouble: avoiding food, bad breath, a sore mouth or broken teeth

Is the practice easy to get to?

Yes. We are on the ground floor with wheelchair access, parking nearby and Padstow Station a one-minute walk away.

What about cost?

We accept all health funds and treat DVA patients. For larger treatment, we provide a written plan with the cost of each visit, and treatment can often be staged.

Common questions about dental care for older adults

How often should an older adult have a check-up?

It depends on their risk. For many people with a dry mouth or gum disease, every three to six months is appropriate.

Can treatment be done under sedation?

Often, yes, after the sedationist reviews their medical history.

Do people with dentures still need check-ups?

Yes. We check the fit, the gums and the soft tissues of the mouth.

Can you see my parent if they have dementia?

Yes. Tell us beforehand so we can plan a calm, unhurried visit.
