Can Wisdom Teeth Come Through at 60?

Wisdom teeth can and occasionally do come through at 60, though it is uncommon. These third molars typically erupt between the ages of 17 and 24, but in some people they remain buried in the jawbone for decades, only to partially emerge much later in life as the surrounding bone gradually changes. The process behind this late appearance is different from the normal eruption teenagers experience, and it brings a distinct set of risks that make the situation worth understanding rather than dismissing as a curiosity.

Why Wisdom Teeth Normally Appear in Your Late Teens and Early Twenties

Third molars are the last permanent teeth to develop. They begin forming in the jaw around age seven or eight, and in most people they push through the gums somewhere between 17 and 24 years of age.¹ Whether they actually make it into the mouth depends on how much room is available in the jaw. In modern humans, jaws tend to be smaller than those of our ancestors, which is why impaction is so common. Research on hunter-gatherer populations shows that malocclusion and failure of wisdom teeth to erupt were close to nonexistent in preindustrial groups, whose jaws were simply roomier.² The shift toward softer, more processed diets over the last few thousand years is widely suspected to have reduced jaw growth during childhood, leaving less space for the third molars.

When there is not enough room, the teeth become impacted, meaning they are stuck wholly or partly within the jawbone or under the gum tissue. Many people live their entire lives with impacted wisdom teeth and never know it unless a dental X-ray reveals them. In a large radiographic study of Swedish women across multiple age groups, about 8% had one or more impacted teeth.³ Most of those impacted teeth stayed put, causing no trouble. But “no trouble” does not always mean “no change,” and that distinction matters as you get older.

How a Buried Tooth Can Appear Decades Later

The mechanism behind a wisdom tooth showing up at 60 is usually not the same active eruption that pushes a tooth through the gum in a teenager. Instead, the bone around the tooth gradually resorbs over the years. Jawbone is living tissue that remodels constantly, and in older adults it tends to lose density, especially in the area behind the last molar. As the bone around an impacted wisdom tooth thins and recedes, the tooth that was once deeply embedded can become partially or fully exposed to the mouth.

A study of infections in patients over 60 found exactly this pattern. In most of the older patients with impacted third molars that had become problematic, bone resorption had caused the originally embedded tooth to become exposed inside the mouth. The tooth had not “grown” or erupted in the usual sense; the bone covering it simply retreated enough to uncover it.⁴ This exposure often creates a pocket between the gum and the partially visible tooth, which is extremely difficult to clean and becomes a magnet for bacteria.

Another mechanism involves cyst formation. Dentigerous cysts, which develop from the tissue surrounding an unerupted tooth, can slowly enlarge over years and physically displace the tooth into an abnormal position. In some cases the cyst pushes the tooth closer to the surface or into contact with other structures, effectively mimicking eruption. Dentigerous cysts are commonly associated with impacted third molars, and when they form, the standard approach is to remove the tooth and the cyst together.⁵

What Problems Late-Emerging Wisdom Teeth Cause

A wisdom tooth that becomes exposed in an older person’s mouth is not the same as one that erupted cleanly in a 20-year-old. It typically comes through at an odd angle, only partially breaks the gum surface, or sits in a position where effective cleaning is impossible. The consequences fall into a few categories.

Infection is the most common. The same study of patients over 60 documented a range of infectious problems tied to impacted wisdom teeth: pericoronitis (infection of the gum tissue around a partially erupted tooth), secondarily infected dentigerous cysts, deep abscesses, limited osteomyelitis, and even a skin fistula draining from the jaw.⁴ These infections can be harder to manage in older adults, whose immune response and healing capacity tend to be reduced compared to younger patients.

Damage to the neighboring second molar is another significant concern. Research on elderly patients with erupted third molars found that wisdom teeth at any stage of eruption are a risk factor for both periodontal disease and cavities in the adjacent second molar. The side of the mouth where a wisdom tooth was present had significantly higher probing depths around the second molar and a significantly higher rate of cavities on that tooth, compared to the opposite side where the wisdom tooth had been removed.⁶ This finding held regardless of whether the wisdom tooth erupted to the same level as the second molar or sat lower. In other words, a wisdom tooth does not need to be fully erupted to create problems for its neighbor; partial emergence is enough.

Less commonly, an impacted wisdom tooth can be associated with pathological changes in the surrounding tissue. In the Swedish study that followed women over 12 years, pathological conditions were found in about 16% of those who had impacted teeth. Most were relatively mild, such as a slightly widened follicle or minor crown resorption. A follow-up examination 12 years later showed that conditions had remained unchanged in 85% of cases, with only small changes in the rest.³ So while serious complications from completely buried, asymptomatic wisdom teeth are the exception rather than the rule, they do happen, and they become more likely the longer the tooth sits there.

Why Extraction Gets Harder With Age

If you are 60 and a wisdom tooth has started causing trouble, one of the first things an oral surgeon will tell you is that the extraction itself carries more risk than it would have at 20. A retrospective study of surgical extractions in patients over 60 concluded bluntly that the procedure is “fraught with a high risk of possible complications” in this age group.⁷

Several factors work against you. The bone surrounding the tooth becomes denser and less elastic over the decades, making it harder to luxate the tooth out of its socket. The roots may have completed their development long ago and can be curved, hooked, or divergent in ways that complicate removal. Blood supply to the area and healing capacity both decline with age. And many older adults are on medications such as blood thinners that introduce additional management challenges during surgery.

One age-related change that is particularly relevant to wisdom teeth is hypercementosis, an excessive buildup of cementum on the root surface. A study using cone-beam CT scans found that the incidence of hypercementosis in lower wisdom teeth increases dramatically with age: essentially 0% in people under 20, about 14% in the early twenties, rising to roughly 83% in the 30-to-39 age group, and reaching nearly 97% in people aged 60 and older.⁸ This extra root material makes the tooth bulkier and can cause it to fuse partially with the surrounding bone, a condition called ankylosis. An ankylosed tooth essentially becomes welded to the jaw, and extracting it requires removing some of the surrounding bone as well.

To Remove or Not to Remove

The decision about what to do with a wisdom tooth at 60 depends heavily on whether the tooth is causing symptoms. If it is completely buried, shows no signs of cyst formation, is not associated with infection, and is not damaging neighboring teeth, there is a strong case for leaving it alone and monitoring it with periodic X-rays. A Cochrane systematic review on this topic found insufficient evidence to recommend routine removal of asymptomatic, disease-free impacted wisdom teeth. The reviewers concluded that patient values should be considered and clinical judgment used to guide shared decision-making, and that if the decision is to keep the teeth, regular clinical assessment is advisable to catch problems early.⁹

A review in the European Journal of Clinical and Experimental Medicine reached a similar position, recommending that in older patients, asymptomatic third molars should be retained and watchfully monitored, with removal reserved for cases where clear clinical or radiological symptoms develop.¹⁰

The calculus shifts when symptoms are present. Recurrent infections, cyst formation, progressive bone loss, or decay spreading to the second molar all tip the balance toward extraction, even though the surgery is more complex in an older patient. The risk of doing nothing in these cases typically outweighs the surgical risk, because untreated infections in the jaw can spread to deeper spaces and become life-threatening. But the decision involves weighing the patient’s overall health, medications, and ability to tolerate a surgical procedure, and the conversation between patient and surgeon matters more at 60 than it does at 25.

When a Wisdom Tooth Surprises You on a Routine X-Ray

Many people over 60 discover they have impacted wisdom teeth only because they show up incidentally on an X-ray taken for another reason. A reported case involved a 72-year-old woman whose impacted lower wisdom tooth was found only because a panoramic X-ray had been ordered to investigate an infection around an upper wisdom tooth on the opposite side.¹¹ The impacted tooth had sat silently for decades, and without the unrelated problem, it might never have been noticed.

This is not unusual. Panoramic radiographs cover the entire jaw and routinely reveal impacted teeth, cysts, and other incidental findings that have nothing to do with the original complaint. Cone-beam CT imaging can reveal even more detail, including the number and direction of roots and their relationship to the nerve that runs through the lower jaw. One randomized trial found that cone-beam CT showed root number and divergence more reliably than panoramic X-rays, though it did not reduce the rate of complications after surgery itself.¹² For older patients where the roots are likely to be fully formed and potentially irregular, that extra detail can help a surgeon plan the safest approach.

Finding a buried wisdom tooth at 60 or 70 that is not causing problems is genuinely a situation where the best response is often to note it, schedule follow-up imaging in a year, and otherwise leave it alone. The monitoring itself is the intervention.

Can New Teeth Really “Grow” in Old Age?

It is worth clearing up a common confusion. When someone says their wisdom tooth “came through” at 60, they sometimes imagine the tooth developed fresh in their jaw as an older adult. That is not what happens. The tooth formed decades earlier, usually completing its crown and root development by a person’s mid-twenties at the latest. What changed is the environment around the tooth: the bone receded, a cyst expanded, or the gum tissue broke down enough for the tooth to become visible. The tooth itself was always there.

Supernumerary teeth, extra teeth beyond the normal 32, can occasionally add to the confusion. These are sometimes discovered late in life when they cause symptoms or show up on imaging. A review of cases involving ectopic supernumerary fourth molars found that the average age at diagnosis was about 48, suggesting these teeth can go undetected for a long time.¹³ A person finding such a tooth in their jaw at 50 or 60 might reasonably think they grew a new tooth, but the tooth had been developing silently for years or decades.

Why Jaws Became Too Small for Wisdom Teeth

The reason so many modern humans end up with impacted wisdom teeth in the first place is an evolutionary mismatch. Our distant ancestors ate tough, fibrous diets that required heavy chewing from childhood onward, and that mechanical stimulus helped their jaws grow larger. The shift toward agriculture and, more recently, industrially processed foods reduced the forces acting on growing jaws. Researchers have described this as a “jaw epidemic”: preindustrial populations had roomy jaws with space for all 32 teeth, while modern populations frequently do not.² The exact mechanisms linking diet, jaw development, and tooth crowding remain uncertain, but the temporal and geographic correlation is strong: as lifestyles industrialize, wisdom tooth impaction rates rise.

This background matters for the question of late eruption because it explains why the teeth get stuck in the first place. In a jaw with adequate space, wisdom teeth erupt normally and function like any other molar. The problem is not the tooth; it is the jaw that never grew large enough to accommodate it. And that mismatch does not resolve with age. If anything, the progressive bone loss that comes with aging can shift the problem from a buried-and-stable tooth to a buried-and-now-exposed one, which is exactly how a 60-year-old ends up at the dentist with a wisdom tooth poking through the gum for the first time.

Keeping an Eye on Aging Wisdom Teeth

If you are past 60 and know you still have impacted wisdom teeth, a few practical points are worth keeping in mind. First, regular dental imaging matters. The same Swedish study that found most impacted teeth stay stable over 12 years also found that changes, when they did occur, were generally small.³ Periodic panoramic X-rays, taken every few years if there are no symptoms, can catch early cyst formation or bone changes before they become emergencies.

Second, pay attention to new symptoms in the back of the jaw. Persistent dull aching, swelling in the gum behind your last molar, a bad taste or smell from that area, or difficulty opening your mouth fully can all signal that an impacted tooth is becoming a problem. These symptoms can mimic other conditions, including temporomandibular joint issues or periodontal disease unrelated to wisdom teeth, so getting a proper evaluation rather than guessing is important.

Third, if you are told you need an extraction and you are on blood thinners, anti-resorptive medications for osteoporosis, or immunosuppressive drugs, make sure your oral surgeon coordinates with the physician managing those medications. These drugs do not necessarily rule out surgery, but they affect how the procedure is planned and how the wound heals afterward. The case report of a geriatric patient on dabigatran (a blood thinner) who needed a dentigerous cyst and wisdom tooth removed illustrates that these surgeries are done in older patients on complex medication regimens, but they require careful management.⁵

Finally, the health of the second molar next door deserves attention. Because wisdom teeth that are partially erupted or poorly positioned can drive decay and gum disease in the neighboring tooth, keeping that second molar clean and monitored is an indirect way of managing the wisdom tooth problem. In some cases, losing the second molar to decay caused by a wisdom tooth ends up being the bigger functional loss, since second molars are far more useful for chewing than wisdom teeth. Catching that damage early gives you more options.⁶
