Short answer
Teeth can last a lifetime, but the risks change with age. Older adults are more likely to have dry mouth from medications, cavities on exposed root surfaces, gum disease, worn or cracked teeth and older fillings or crowns that need attention. Regular exams, fluoride, daily cleaning adapted to your hands and abilities, and an up-to-date medication list help catch problems early. Many seniors without dental insurance may qualify for the Canadian Dental Care Plan.
Key takeaways
- Dry mouth from medications is one of the biggest drivers of new cavities in older adults.
- Exposed root surfaces decay more easily than enamel, so fluoride matters more, not less, with age.
- Dentures and implants still need regular checks of the gums, bite and mouth tissues.
- Seniors without dental insurance may qualify for CDCP coverage if family income is under $90,000.
More Canadians are keeping their natural teeth well into their 70s, 80s and beyond. That is good news, but it also means more years in which teeth, gums and older dental work need care. The challenges of the senior years are different from those of childhood or mid-life, and a few changes to routine can prevent most of them.
How does the mouth change with age?
Teeth do not wear out on a schedule, but several changes become more common with age:
- Dry mouth. Saliva protects teeth by washing away food and neutralizing acid. Hundreds of common medications reduce saliva flow, including some for blood pressure, depression, allergies, pain and bladder control.
- Gum recession. Years of gum disease, grinding or hard brushing can expose the root surfaces of teeth.
- Root cavities. Root surfaces are covered by softer cementum rather than enamel, so they decay faster once exposed.
- Wear and cracks. Decades of chewing and grinding flatten and weaken teeth, and large old fillings can leave the remaining tooth prone to fracture.
- Ageing dental work. Fillings, crowns and bridges placed years ago can leak, chip or develop decay at their edges.
- Changes in health and dexterity. Arthritis, vision changes, tremor or memory problems can make thorough cleaning harder.
None of these changes is inevitable, and none means teeth are destined to be lost. Most of them develop slowly, which is good news: they can be found early at regular checkups and managed with small, conservative steps rather than large treatments. The aim is to spot the trend, such as a drier mouth or a new spot of root decay, before it becomes a broken tooth or an emergency visit.
Why dry mouth deserves attention
Dry mouth is one of the most common reasons older adults suddenly develop several new cavities after years of stable dental health. Our guide to dry mouth causes and remedies covers it in more depth. Signs include a sticky or burning mouth, difficulty swallowing dry foods, a need to sip water while talking, cracked lips and dentures that rub or do not stay in place.
What can help:
- Bring an up-to-date medication list to every dental visit, including over-the-counter products and supplements.
- Ask your physician or pharmacist whether any medication could be adjusted. Never stop a medication on your own.
- Sip water through the day, and limit alcohol and caffeine, which can dry the mouth further.
- Use sugar-free gum or lozenges, ideally with xylitol, to stimulate saliva.
- Ask your dentist about high-fluoride toothpaste, fluoride varnish or saliva substitutes.
Gum disease after 60
Gum disease often progresses quietly, without pain. Bleeding when brushing, bad breath, gums pulling away from teeth, loose teeth or changes in your bite are signs to have checked. Gum disease is also associated with diabetes and heart disease, and managing it is part of caring for your overall health.
Treatment usually starts with careful cleaning above and below the gumline, followed by regular maintenance visits. Our article on early signs of gum disease explains what to watch for.
Caring for dentures, implants and older dental work
- Dentures: Clean them daily with a soft brush and a denture cleaner, not regular toothpaste, which can scratch them. Take them out overnight unless your dentist advises otherwise, and keep them moist. Jaw bone changes over time, so dentures that once fit well can loosen and cause sores. See our guide to daily denture care.
- Implants: They cannot decay, but the gums and bone around them can become inflamed. Clean around them as carefully as natural teeth and keep regular checks.
- Crowns and bridges: Clean under bridges with floss threaders or interdental brushes, and watch for food trapping or bad taste, which can signal a problem at the margin.
A home-care routine that works with your hands
The aim is the same at any age: remove plaque from every surface once a day, and use fluoride twice a day. The tools can change:
- An electric toothbrush does much of the work for people with arthritis or limited grip.
- Wide-handled brushes or a foam grip are easier to hold.
- Interdental brushes or water flossers are often easier than string floss.
- High-fluoride toothpaste, if your dentist recommends it, adds protection for exposed roots.
- Good lighting and a magnifying mirror help when vision is limited.
Caregivers who help with brushing can ask the hygienist for a short demonstration. A few minutes of guidance makes daily care much easier for both people.
Chewing, nutrition and overall health
Teeth affect more than your smile. Missing teeth, loose dentures or a sore mouth can push people toward soft, processed foods and away from fresh vegetables, fruit, nuts and lean proteins. Over time that can affect nutrition, energy and weight, which matters a great deal in later life.
If chewing has become difficult, tell your dentist. Options might include adjusting or relining a denture, replacing a missing tooth or repairing a broken one. Until then, a few practical changes help:
- Cut food into smaller pieces and chew on both sides if you can.
- Choose softer, nutrient-dense foods such as eggs, fish, beans, yogurt, cooked vegetables and soups.
- Keep sweet snacks and sugary drinks to mealtimes, especially if your mouth is dry.
- Drink water through the day instead of sweetened drinks.
Oral health and general health also affect each other in other ways. Gum disease is associated with diabetes and heart disease, and some medical treatments, such as certain bone-strengthening medications or head and neck radiation, change how dental treatment should be planned. Always tell your dentist about new diagnoses and medications.
How often should seniors see the dentist?
There is no single interval for everyone. Many older adults do well with an exam and cleaning once or twice a year. People with dry mouth, gum disease, frequent new cavities or a lot of dental work may need visits every three or four months. Even people with no natural teeth benefit from an annual exam of the gums, tongue and other soft tissues, including a check for early signs of oral cancer.
Our article on why regular dental check-ups matter explains what an exam looks for.
Paying for dental care in retirement
Many people lose workplace dental coverage when they retire. The Canadian Dental Care Plan may help: it is available to eligible Canadian residents without access to dental insurance whose adjusted family net income is under $90,000. It can cover exams, cleanings, fillings, extractions and removable dentures, with income-based co-payments, frequency limits and some services that need preauthorization. Implants and bridges are not covered. Our guide to CDCP coverage explains the details.
When to book sooner
Do not wait for a routine visit if you notice:
- A sore, patch or lump in the mouth that has not healed within two weeks
- A loose tooth, or a change in how your teeth meet
- Pain, swelling or a bad taste around a tooth or implant
- A broken tooth, filling or denture
- Dentures that rub, slip or make chewing difficult

Frequently asked questions
How often should seniors see the dentist?
Most older adults benefit from an exam and cleaning at least once or twice a year. People with gum disease, dry mouth, frequent cavities or many restorations may need more frequent visits. Your dentist will suggest an interval based on what your mouth shows.
Do I still need checkups if I have full dentures?
Yes. A yearly visit lets the dentist check the fit of the dentures, look for sore spots and examine the gums, tongue and other soft tissues for changes, including early signs of oral cancer.
Is it normal for gums to recede with age?
Some recession is common, but it is not simply caused by ageing. Gum disease, hard brushing and grinding contribute. Recession exposes root surfaces that are prone to sensitivity and decay, so it should be monitored.
Does CDCP cover seniors?
The Canadian Dental Care Plan is open to eligible Canadian residents of any age who do not have access to dental insurance and have an adjusted family net income under $90,000. It can cover exams, cleanings, fillings, extractions and dentures, with income-based co-payments and plan limits.
What if brushing is hard because of arthritis?
An electric toothbrush, a toothbrush with a wider handle, floss holders or interdental brushes can make cleaning easier. Your hygienist can recommend tools that suit your hands.
