Harvard Health published a short piece last fall called The Senior's Guide to Dental Care. It is good, and it is short. Brush, floss, see your dentist twice a year, watch for dry mouth. All true. But I see patients in their sixties, seventies, and eighties every week at both of our offices, and the questions they actually ask are bigger than that. Why am I suddenly getting cavities again at 72? Does Medicare pay for any of this? My denture used to fit, what changed? Is it worth doing an implant at my age?
So here is the longer version. This is what I would tell my own parents.
Your teeth are not "done" changing
Most people assume that once you reach adulthood, the mouth settles down. It does not. Three things shift after 60 that change how you need to care for your teeth.
Gums recede. Decades of brushing, gum disease, and simple wear pull the gumline back and expose the root of the tooth. Root surfaces are softer than enamel and decay much faster. That is why so many of my older patients who went thirty years without a cavity suddenly have three. Nationally, about one in eight adults over 65 has untreated decay right now, according to the CDC's oral health surveillance data, and most of what I see in that age group is on the roots, not the chewing surfaces.
Saliva drops. More on this below, because it is the single most important thing on this list.
Gum disease adds up. Periodontitis is slow. It does not hurt until it is advanced, and by 65 roughly six in ten adults have some degree of it, based on national survey data published in the Journal of the American Dental Association. Most of it is moderate and very treatable. The problem is that untreated, it is the main reason people lose teeth in their seventies.
None of this is a reason for alarm. It is a reason to adjust the routine.
Dry mouth is the root of most senior dental problems
If you take blood pressure pills, an antidepressant, an antihistamine, a diuretic, a bladder medication, or something for pain, there is a good chance your mouth is drier than it used to be. The American Dental Association lists all of those classes as common causes, and the National Institute of Dental and Craniofacial Research says hundreds of medicines can cause the salivary glands to make less saliva. A review of population studies found dry mouth in about one in five people overall, and more often in older adults.
Saliva is not just for comfort. It washes food off the teeth, buffers acid, and carries the minerals that repair early enamel damage all day long. Take it away and the teeth are defenseless, especially those exposed roots. Dry mouth plus receded gums is how a 75-year-old gets cavities along the gumline of every tooth in a year.
What actually helps:
- •Sip water through the day. Not a gulp with pills, small sips constantly.
- •Sugar-free gum or mints with xylitol after meals. Chewing is the best natural saliva stimulant there is.
- •Prescription-strength fluoride toothpaste at 5,000 ppm. The ADA's clinical guideline on root cavities recommends 5,000 ppm toothpaste as one option for stopping decay on root surfaces, alongside silver diamine fluoride and fluoride varnish. We prescribe it routinely. Use it at night and do not rinse afterward.
- •Fluoride varnish at your cleaning visits.
- •Alcohol-free mouthwash only. Alcohol dries the mouth further, which is the opposite of what you want.
- •Ask your physician whether a drier-mouth medication has an alternative. Sometimes it does. Never stop a medication on your own.
We wrote a longer post on how saliva protects your teeth if you want the full picture.
Gum disease and the rest of your body
The Harvard article touches on this, and it is worth being precise, because the internet overstates it.
The strongest connection is diabetes. It runs both ways: diabetes makes gum disease worse, and gum inflammation makes blood sugar harder to control. The CDC reports that adults over 50 with diabetes are about half again as likely to have severe tooth loss, and that treating gum disease measurably improves glycemic control. If you are diabetic, your gums are part of your diabetes care. I mean that literally.
Heart disease and stroke are associated with gum disease, and the American Academy of Periodontology considers that association real and independent of the usual risk factors. Whether treating your gums lowers your heart risk is not proven. Do not let anyone sell you a deep cleaning as a heart treatment. Get your gums treated because it saves your teeth.
Pneumonia is the one nobody talks about. In older adults, especially anyone with swallowing trouble or in assisted living, bacteria from an unclean mouth get inhaled into the lungs. A review in the journal Age and Ageing found professional oral care lowered the risk of aspiration pneumonia in residential care. If you are helping care for a parent, their mouth matters more than you think.
Dementia is the headline everyone asks about. There is a real statistical link between tooth loss and cognitive decline. A 2026 study of over 8,000 adults found people missing 9 to 16 teeth had about a 28% higher risk of cognitive impairment. But association is not cause. People with early dementia also brush less, so some of this runs the other direction. My honest read: keep your teeth and your gums healthy because it clearly helps you eat, speak, and stay well. If it turns out to protect your brain too, that is a bonus.
Medicare, and what you will actually pay
This is where I get the most frustrated questions, so let me be plain.
Original Medicare does not cover routine dental care. No cleanings, no fillings, no extractions, no dentures, no implants. Medicare.gov says so directly. The exceptions are narrow, like a dental exam before a transplant.
Medicare Advantage plans usually do include some dental benefit. In 2026, 98% of Advantage enrollees have access to one. But the benefits vary enormously. Some cover only cleanings and X-rays. Others cover crowns and dentures up to an annual cap, and that cap is usually low enough that a single crown can use most of it. Read the dental section of your plan before you need it, not after.
We are in network with Aetna and Humana Medicare Advantage dental plans at our Ahwatukee office, and with Aetna, Delta Dental, and Humana Medicare Advantage at Chandler. Bring your card and we will check your benefits before you commit to anything.
If you have no dental coverage, both offices have an in-house membership plan that covers your preventive visits for a flat yearly fee and discounts the rest. For a retiree paying cash, it is usually the cheaper route.
Dentures, and why they stop fitting
A denture does not wear out so much as the jaw underneath it shrinks. Once the teeth are gone, the bone that held them slowly resorbs, and a denture made five years ago is sitting on a ridge that is no longer there. That is why it starts to rock, why food gets underneath, and why you find yourself buying more adhesive. The ADA's guidance on dentures is to have them evaluated once they are past five years old and to treat adhesive dependence as a sign it needs relining or replacing, not as a solution.
Daily care is simple but people skip it. Take them out at night, every night. Tissue that never gets a break develops a fungal irritation called denture stomatitis that is uncomfortable and completely avoidable. Brush the denture with a non-abrasive cleaner, soak it overnight, and brush your gums and tongue with a soft brush. Never hot water, it warps the acrylic.
For a lower denture that will not stay put, two implants under it changes everything. A ten-year study of two-implant lower overdentures found about 93% of implants still in place in patients aged 60 to 80 at treatment, who did as well as younger patients, and my experience matches that. We have placed them for patients in their eighties. Age by itself is not the deciding factor, bone and general health are. If you want to read about someone weighing exactly this question for her mother, this post covers it.
Tell us about your bones
If you take a medication for osteoporosis, we need to know before any extraction. Oral bisphosphonates like alendronate carry a very small risk of a jaw healing problem called osteonecrosis after surgery. The ADA puts the risk at well under one in ten thousand for the pills, but it is much higher for the IV versions used in cancer care, and it rises after a couple of years on the drug. Denosumab injections count too. Knowing this changes how we plan an extraction. It does not mean you cannot have one.
Same goes for blood thinners and anything new your cardiologist added. Bring an updated list every visit. It takes thirty seconds and it matters.
Oral cancer screening is part of every exam
The median age at diagnosis for oral cancer is 65, according to the National Cancer Institute. Caught early, five-year survival is about 89%. Caught after it has spread, about 36%. That gap is the whole argument for regular checkups even if your teeth feel fine. We do a full head, neck, and mouth screening at every exam. It takes a few minutes. If you smoke, drink regularly, or have a sore in your mouth that has not healed in two weeks, do not wait for your next cleaning.
The routine, adjusted for age
Take the Harvard basics and add these.
Switch to an electric toothbrush if your hands are stiff. A Cochrane review found powered brushes remove modestly more plaque than manual, and the real advantage for arthritic hands is that it does the work for you. A rotating-oscillating head with a two-minute timer is what I recommend.
Use interdental brushes if floss is hard. Those little bottle-brushes on a handle clean between teeth and around bridges, and for many older patients they are easier and more effective than string floss. Water flossers are fine as well, particularly around implants.
Brush at the gumline. That is where the root decay starts. Soft bristles, 45 degrees, short strokes.
Come more often if you are higher risk. Twice a year is the default, but if you have dry mouth, gum disease, diabetes, or a lot of crowns and bridges, I will usually ask to see you every three or four months. It is not upselling. Root decay moves fast, and I would rather catch it as a spot I can treat with fluoride than a cavity I have to fill.
Be conservative about treatment, but do not defer it. I do not believe in over-treating anyone, and that goes double for someone on a fixed income. But a small root cavity at 70 is a fluoride prescription and a watch. The same cavity at 73 is a root canal or an extraction. The cheap fix only stays cheap if you take it early.
Frequently asked questions
I have not been to a dentist in years. Is it too late?
No. Some of my most rewarding patients walked in at 75 after a decade away. We start with an exam and X-rays, deal with anything urgent, and then build a plan in order of what matters most. Nobody gets a lecture.
Am I too old for implants?
Almost never on the basis of age alone. What matters is your bone, your overall health, and your medications. We will tell you honestly if a conventional denture or a bridge is the better call. Our dental implants page explains the options.
Do you take my Medicare Advantage plan?
Ahwatukee is in network with Aetna and Humana Medicare Advantage dental. Chandler is in network with Aetna, Delta Dental, and Humana. Call either office with your card handy and we will verify your specific plan and its annual cap before you come in.
My mouth is so dry I wake up at night. Is that normal?
It is common, but it is not something to just live with. Waking with a dry mouth is often medication-related, and sometimes it points to sleep apnea, which we can also screen for. Tell us. There are things we can do about it.
Is the Chandler office close to Sun Lakes?
Yes. We are on Riggs Road, about a five-minute drive from Sun Lakes, and a lot of our patients there are retirees. Details are in our Sun Lakes post.
