Wisdom teeth typically emerge between ages 17-25, but not everyone experiences problems. Research indicates that approximately 5 million Americans undergo wisdom tooth extraction annually, with an estimated 50% of patients having at least one third molar removed by age 25. Common issues requiring removal include impaction (when teeth lack space to emerge properly), crowding, tooth decay, infection, and pain. The American Association of Oral and Maxillofacial Surgeons recommends evaluation by early adulthood to assess presence, disease status, and management options. Warning signs include persistent pain at the back of the mouth, swelling or redness, jaw stiffness, and associated headaches or earaches. However, fully erupted wisdom teeth that are functional, painless, cavity-free, and maintainable with proper hygiene may not require extraction. Regular dental monitoring with X-rays remains essential even for asymptomatic wisdom teeth, as problems can develop over time.
As the name suggests, wisdom teeth emerge much later than your other teeth, and it’s not uncommon for these to arrive well into your twenties. On the whole, wisdom teeth appear without any pain or problems.
However, in some cases, their arrival can cause some complications or discomfort, making removal the best course of action. In this guide, we will look at when and why wisdom teeth might need to be removed, with the aim to support you to make a more informed decision regarding your own oral health.

What Are Wisdom Teeth and When Do They Emerge?
Wisdom teeth develop much later than your other teeth, and in some cases, they may not even arrive at all. For those who do grow wisdom teeth, it is expected that they will arrive between your late teens and mid-twenties, but of course, this is just an approximation.
Historically, wisdom teeth were required to grind tough foods, but a change in diet in today’s world has almost left them without purpose.
Additionally, modern developments in jaw size and structure means that many people simply don’t have enough room for wisdom teeth, so when they do emerge, this can cause significant pain or other problems.
5 Common Problems Associated with Wisdom Teeth
Not every person will experience difficulties when their wisdom teeth arrive. However, here are the most common complications they can bring:
- Discomfort: Emerging wisdom teeth can add pressure to the jaw and gums, making this an uncomfortable experience to go through.
- Impaction: Impaction happens when wisdom teeth try to break through, but have no room to grow due to existing teeth. Impacted wisdom teeth can be fully or partially blocked and can also become quite painful.
- Crowding: A lack of space can impact the positioning of your existing teeth, as they try to make room for the wisdom teeth to emerge.
- Tooth decay: Wisdom teeth are much more likely to have decay issues due to their hard-to-reach position in the mouth.
- Infection: Gums can become infected where partially erupted wisdom teeth create a pocket of bacteria. According to the American Association of Oral and Maxillofacial Surgeons, pericoronitis (inflammation of soft tissues surrounding a partially erupted tooth) accounts for 25-30% of third molar extractions, highlighting the significant role infection plays in extraction decisions.
Signs & Symptoms That Indicate a Problem
There are a number of warning signs your body will give you if your wisdom teeth are becoming a problem. Here’s what to look out for:
- Pain: Pain, throbbing or any form of persisting discomfort at the back of your mouth is not normal, and could be a sign of problematic wisdom teeth.
- Swelling: If you notice any redness or swelling in the back of your mouth, we would recommend getting this checked out.
- Stiff jaw: Impacted wisdom teeth can also affect the jaw muscles, making it difficult to open your mouth fully.
- Other aches and pains: Jaw pressure may also impact other areas and cause headaches or earaches.
Although these symptoms may seem minor at first, however if ignored, they are likely to become much worse. If you notice any of these, or feel that something isn’t right, it’s always best to get checked over by your dentist.
When Extraction Becomes Necessary: Medical Indications
Many wisdom teeth emerge without any issues, and this does not impact the individual in any way. However, these are the times when extraction may be the best way forward:
- Impaction: Impacted wisdom teeth are unlikely to emerge properly; therefore, it is often better to remove them altogether.
- Recurring issues: Repetitive occasions of gum disease or other infections will result in the problem tooth being removed.
- Crowding: Wisdom teeth will be extracted if they cause excessive crowding in the mouth, or their arrival damages other teeth in the process.
- Orthodontic purposes: If you’ve previously had braces, it is possible that the new wisdom tooth will reconfigure the alignment of your existing teeth.
The Evaluation Process: X-rays and Dental Assessment
Although it’s beneficial to remain informed regarding dental treatment and processes, your dentist will have the final say when it comes to your wisdom tooth removal.
You will be invited to a consultation where you can share your concerns, and your dentist will complete a full medical and dental history.
This will include a physical examination of your teeth and gums, as well as an X-ray so they can see the exact position of your wisdom tooth. Research published in Frontiers in Dental Medicine found that by age 25, approximately 80% of patients underwent at least one tooth extraction, with an estimated 50% undergoing third molar extraction, making wisdom tooth evaluation a common and important part of young adult dental care.
What to Expect During and After Wisdom Teeth Removal
Here’s what will happen during and after your procedure:
During
- Depending on your situation, your dentist will perform the procedure under local or general anaesthetic or sedation.
- For impacted teeth, a small incision will be made into the gum.
- The tooth will be extracted either as a whole or in parts.
- The area will be cleaned and stitched if necessary.
After
- Expect to experience some mild pain, swelling or bruising around the jaw.
- Control the discomfort with over-the-counter medication or ice packs.
- Restrict your diet for a few days to contain softer foods.
- Keep the area clean to avoid infection.
Living with Wisdom Teeth: When Removal Isn’t Needed
The emergence of wisdom teeth doesn’t always result in removal; many people live with their wisdom teeth without any issues at all.
If your wisdom teeth have fully erupted, and you haven’t noticed any pain, overcrowding or alignment concerns with your surrounding teeth, then it’s likely that you are one of the lucky ones. With that being said, just as the same as your other teeth, wisdom teeth should be checked regularly, as even those that are symptom free could have an upcoming concern.
A routine check-up with your dentist enables them to pick up any issues early on, to prevent them from becoming a bigger problem down the line. However, if you do notice anything out of the ordinary, don’t wait until your next appointment, and get in touch with your dentist as soon as possible.
Early detection could save you a lot of time, money and pain in the future.
Frequently Asked Questions (FAQs)
At what age should wisdom teeth be evaluated or removed?
The American Association of Oral and Maxillofacial Surgeons recommends that wisdom teeth be evaluated by an oral surgeon during early adulthood, typically between ages 17-25. This is considered the optimal timeframe because the roots are not yet fully formed, which can make recovery easier and reduce the risk of complications. Research shows that by age 25, approximately 50% of patients have undergone at least one third molar extraction. However, wisdom teeth can be removed at any age from adolescence to older adulthood if problems develop. The best time for removal depends on individual circumstances including tooth position, root development, and whether symptoms or complications are present. Regular dental X-rays and examinations during the late teen years help dentists monitor wisdom tooth development and recommend the most appropriate timing for evaluation or removal.
Do all wisdom teeth need to be removed, or can some be kept?
Not all wisdom teeth require removal. According to dental guidelines, wisdom teeth that are completely erupted, functional, painless, cavity-free, in a hygienic environment with healthy gum tissue, and disease-free may not need extraction. Studies suggest that a significant portion of wisdom tooth extractions may be unnecessary—some research indicates up to 60% of extractions are performed prophylactically on asymptomatic teeth. However, even healthy-appearing wisdom teeth require regular professional monitoring because problems can develop over time. Retained wisdom teeth need annual check-ups, professional cleaning, and periodic X-rays to monitor for changes in health status. The decision to keep or remove wisdom teeth should be made on an individual basis through shared decision-making between patient and dentist, considering factors like tooth position, ability to maintain proper hygiene, risk of future complications, and personal circumstances.
What are the risks and complications of wisdom tooth extraction?
While wisdom tooth extraction is a common and generally safe procedure, it does carry some risks. The most common complications include temporary pain, swelling, and bruising, which typically peak within 48-72 hours and resolve within 7-10 days. Dry socket (alveolar osteitis) occurs in approximately 20-30% of impacted mandibular extractions but only 1-5% of non-impacted tooth extractions. Less common but more serious complications include temporary or permanent nerve injury affecting sensation in the lip, tongue, or cheek (occurring in 0.4-8.4% of cases, with permanent injury under 1%), infection (0.8-4.2% of cases), prolonged bleeding, and rarely, jaw fracture. Risk factors that increase complication rates include smoking (which triples complication risk), taking oral contraceptives (which doubles dry socket odds), older age at extraction (patients over 25 have higher surgical difficulty), and poor oral hygiene. Your oral surgeon will discuss these risks during consultation and provide specific guidance based on your individual case, tooth position, and health status.
