Wisdom teeth, or third molars, are the last set of molars that typically emerge in the late teens to early twenties. For many individuals, these teeth can become problematic, leading to discomfort, infection, or crowding of other teeth. One of the most common dental surgeries performed is the removal of wisdom teeth. But when is the best time to have them taken out? What is the average age, and why does it matter?
In this comprehensive guide, we will explore the average age to get wisdom teeth removed, the factors that influence the timing of removal, and what patients can expect before, during, and after the procedure. Whether you’re a parent, a teenager, or an adult wondering about your own dental health, this article provides professional insights that will help you understand this significant dental milestone.
Understanding Wisdom Teeth
Wisdom teeth are the third and final set of molars that typically emerge in the back corners of the mouth. Most people have four wisdom teeth—two on the top and two on the bottom. Unlike other teeth, wisdom teeth usually erupt much later, typically between the ages of 17 and 25.
Historically, these molars served a purpose for our ancestors, who had larger jaws and diets that required more chewing power. However, as human diets and jaw sizes have evolved, these once-useful teeth often no longer fit comfortably in the modern mouth. This misalignment often leads to a recommendation for removal.
Why Are Wisdom Teeth Removed?
Not everyone needs to have their wisdom teeth removed, but a significant portion of the population does. The primary reasons include:
Impaction: Wisdom teeth may not have enough room to erupt properly, becoming trapped in the gums or jawbone.
Crowding: The eruption of wisdom teeth can push other teeth out of alignment.
Infection: Partially erupted teeth can create flaps of gum tissue that trap food and bacteria, leading to infections.
Tooth Decay: Because of their location, wisdom teeth are harder to clean and more prone to cavities.
Cysts or Tumors: In rare cases, wisdom teeth can cause cysts to form, which can damage the jawbone or surrounding teeth.
When Do Wisdom Teeth Usually Erupt?
Most individuals experience the eruption of their wisdom teeth between the ages of 17 and 25, though the exact age can vary depending on genetic and environmental factors. Some people may see them emerge as early as 16, while others may not experience eruption until their late twenties—or not at all.
It’s important to note that just because the teeth haven’t erupted doesn’t mean they’re not present. A dental X-ray often reveals the presence and position of wisdom teeth well before they break through the gums.
Average Age to Get Wisdom Teeth Removed
The average age to get wisdom teeth removed is between 18 and 24 years old. Most dental professionals recommend evaluating the position of the wisdom teeth during the late teenage years, usually around age 17 or 18. If there are signs of potential problems—such as impaction, misalignment, or crowding—extraction is often advised sooner rather than later.
There are several reasons why this age range is ideal:
1. Root Development Is Not Yet Complete
In younger patients, the roots of the wisdom teeth are still developing. Removal during this stage is generally easier and less traumatic for the surrounding bone and tissues. The incomplete root structure allows for a simpler extraction and quicker healing.
2. Lower Risk of Complications
The younger the patient, the better the body tends to respond to surgery. Younger individuals have better healing capacity, lower risk of infection, and generally recover faster compared to older adults.
3. Preventive Benefit
Even if wisdom teeth are not currently causing problems, early removal can prevent future issues. Dentists often recommend removing wisdom teeth prophylactically to avoid impaction or infection down the line.
Late Removal of Wisdom Teeth
Although 18 to 24 is the average age for removal, many adults have their wisdom teeth extracted later in life. There are several reasons why someone might delay the procedure:
- Lack of symptoms in early years
- Missed dental evaluations
- Fear of surgery
- Financial concerns
However, delaying the removal of wisdom teeth can lead to more complicated extractions. Fully developed roots, denser bone, and increased risk of complications such as nerve damage are more common in older patients. This is why most dental professionals stress the importance of early evaluation and timely intervention.
What Happens If Wisdom Teeth Are Not Removed?
Not all wisdom teeth need to be removed. If the teeth:
Erupt fully and are properly aligned,
Do not affect other teeth,
Are healthy and easy to clean,
…then removal may not be necessary.
However, leaving problematic wisdom teeth can lead to:
- Chronic pain or pressure in the jaw
- Gum infections (pericoronitis)
- Crowding of adjacent teeth
- Decay of neighboring molars
- Jaw cysts or damage to nerves
Each case is unique, so regular dental checkups and X-rays are essential to assess the condition and positioning of wisdom teeth.
What Factors Influence the Timing of Removal?
Several factors affect when wisdom teeth should be removed. These include:
1. Impaction
If the wisdom teeth are impacted (trapped in the jaw or gums), removal is usually recommended as early as possible to prevent cyst formation, infection, or bone loss.
2. Symptoms
Pain, swelling, recurrent infections, or difficulty opening the mouth are signs that wisdom teeth are problematic and should be evaluated for removal.
3. Dental Development
Some patients’ mouths are simply not large enough to accommodate an extra set of molars. X-rays and orthodontic evaluations can determine if there is enough space.
4. Age and Overall Health
Younger patients generally have better surgical outcomes. If health concerns arise, it’s often better to remove wisdom teeth when a person is in good overall health rather than wait until later.
When Is It Too Late to Remove Wisdom Teeth?
There’s technically no maximum age limit for wisdom teeth removal. However, the complexity and risks tend to increase with age. In older adults, potential complications include:
Delayed healing
Greater bone density requiring more invasive surgery
Increased risk of damaging adjacent nerves
That said, if a problematic wisdom tooth becomes infected or causes pain at any age, it should be evaluated and treated accordingly.
FAQs about Wisdom Teeth Removal Age
Q: Can wisdom teeth be removed before they erupt?
A: Yes. In many cases, dental X-rays reveal the position of wisdom teeth before eruption. Removing them before they come in can prevent impaction and crowding.
Q: Is it safe to remove wisdom teeth at age 30 or later?
A: Yes, but the risks are generally higher than for younger patients. Healing takes longer, and the surgery may be more complex.
Q: Do all wisdom teeth need to be removed?
A: Not necessarily. If they are healthy, fully erupted, and properly aligned, they may not need to be extracted. Your dentist can advise you based on your specific situation.
Q: Why do some people never get wisdom teeth?
A: Some individuals are congenitally missing one or more wisdom teeth due to genetic factors. This is perfectly normal and often beneficial.
Conclusion
The average age to get wisdom teeth removed is between 18 and 24, when the teeth have developed enough for extraction but before their roots are fully formed. Early evaluation, usually beginning around age 16 or 17, allows dentists to monitor their development and recommend timely removal when necessary.
If you’re unsure whether your wisdom teeth need to be removed—or if you’re a parent concerned about your teenager’s dental development—schedule a dental evaluation. Proactive care is key to avoiding the potential issues that these third molars can bring.
