Short answer: Not every wisdom tooth needs to be removed. Wisdom teeth that are fully erupted, can be kept clean and have no decay or gum problems can stay in the mouth. Extraction is recommended in cases such as recurring gum inflammation (pericoronitis), decay that cannot be treated, damage to the neighboring tooth or a cyst, or when an orthodontic or surgical plan requires it. The decision is made after an examination and an X-ray assessment.
Third molars, commonly called wisdom teeth, are the last molars to erupt in the mouth and usually start coming in between the late teens and early twenties. Most people have a clear question in mind: when should wisdom teeth be removed, and does every wisdom tooth have to come out? Current dental practice does not recommend routinely removing wisdom teeth that cause no problems; the decision to extract should be based on specific reasons. In this article we look at when extraction is needed, the most suitable age, how wisdom teeth are assessed before orthodontic treatment and when waiting is the right decision.
Should every wisdom tooth be removed?
No, not every wisdom tooth needs to be removed. Wisdom teeth that are fully erupted, bite properly against the opposing tooth, can be cleaned with a toothbrush and floss and have no decay or gum problems can keep functioning in the mouth like the other molars.
Many international guidelines do not recommend preventively removing wisdom teeth that cause no symptoms and show no signs of disease simply because they "might cause problems later." Every surgical procedure carries its own risks, and removing a healthy tooth can mean taking on those risks unnecessarily.
On the other hand, wisdom teeth often cannot erupt fully because there is not enough room in the jawbone; they may stay partly covered by gum tissue or remain completely buried in bone. Such teeth should be monitored regularly even if they cause no symptoms.
Another factor in the decision is the possible risk of the procedure itself. The roots of lower wisdom teeth may lie close to the nerve that supplies feeling to the lower lip and chin, while upper wisdom teeth may sit next to the sinus. Swelling, pain and temporarily limited mouth opening are common after extraction, while dry socket or a temporary change in sensation occur less often. For this reason, the decision is made by weighing the position of the tooth together with the person's overall situation.
When is extraction necessary?
Wisdom tooth extraction is recommended when there is a clear problem such as recurring infection, decay that cannot be treated, damage to the neighboring tooth or the formation of a cyst or tumor, or when it is part of a comprehensive treatment plan. The main situations are:
- Pericoronitis: Inflammation that develops when food and bacteria collect under the gum tissue covering a partially erupted wisdom tooth. It shows up as pain, swelling, difficulty opening the mouth and a bad taste. Recurring pericoronitis is one of the most common reasons for extraction.
- Decay that cannot be treated: Because they sit at the very back of the mouth and are hard to clean, wisdom teeth can develop deep cavities. If a filling or root canal treatment is not suitable, extraction is recommended.
- Damage to the neighboring tooth: A wisdom tooth lying horizontally or at an angle can cause decay, bone loss or root resorption on the back surface of the second molar in front of it. Protecting the second molar is an important factor in the decision to extract.
- Cysts and tumors: Although rare, a cyst can develop around an impacted tooth and is usually treated together with the extraction.
- Gum disease: If deep pockets and bone loss have developed around the wisdom tooth, extraction may be considered.
- Part of a treatment plan: A wisdom tooth may need to be removed as part of orthodontic treatment, jaw surgery or prosthetic planning.
If a wisdom tooth is causing pain and swelling, and there is noticeable facial swelling, difficulty swallowing or fever, see a dentist without delay.
What is the right age for wisdom tooth extraction?
If there is a reason to extract, the procedure is generally easier in young adulthood, while the roots are not yet fully formed, and healing tends to be faster. Between the late teens and mid-twenties, the bone is more flexible, the roots may be farther from the nerve and the capacity to heal is high.
With age, the roots become fully formed, the bone becomes denser and in some cases the roots may lie closer to the nerve in the lower jaw. That is why extractions performed later in life can be more difficult and healing may take longer.
However, this does not mean "let's remove them while young even if there's no problem." The ideal age is about the timing of the procedure when there is a reason to extract. An examination and panoramic X-ray in young people provide information about the direction of the wisdom teeth and their chances of erupting, helping to identify early the teeth that are more likely to cause problems later.
How are wisdom teeth assessed before orthodontic treatment?
Wisdom teeth are routinely assessed before orthodontic treatment; however, not every orthodontic patient needs their wisdom teeth removed. The decision depends on the treatment plan and the position of the teeth.
For many years, wisdom teeth were thought to push the front teeth forward and cause crowding. Current scientific evidence shows that wisdom teeth are not the only or the main cause of crowding in the front of the mouth. Changes in tooth position after treatment depend on many factors, and the main way to prevent them is wearing a retainer.
In orthodontics, removing a wisdom tooth is more often considered in the following situations:
- If the treatment plan requires moving the back teeth backward and the wisdom tooth stands in the way of that movement,
- If jaw surgery is planned and a wisdom tooth is located in the surgical area,
- If the wisdom tooth is negatively affecting the eruption or position of the second molar,
- If there is another problem that requires extraction (such as pericoronitis or decay).
The same assessment applies to clear aligner treatment. During planning, the presence and position of the wisdom teeth are taken into account; if extraction is needed, its timing is set according to the treatment plan. To learn about the stages of clear aligner treatment, see our clear aligner treatment page.
When is waiting the right choice, and how is monitoring done?
If the wisdom tooth causes no problems, its eruption path looks favorable or the risks of extraction outweigh the possible benefits, waiting with regular monitoring is the right decision. For example, for a deeply impacted tooth whose roots are very close to the nerve and which causes no problems, monitoring is often a more appropriate choice than extraction.
During monitoring, the following points are checked:
- At regular dental checkups, the gums around the wisdom tooth and the condition of the neighboring tooth are examined.
- X-rays are taken at intervals your dentist considers necessary to assess the tooth's position, any cyst formation and its effect on the neighboring tooth.
- Special attention is paid to cleaning around partially erupted teeth; brushes with small heads can help in this area.
- If symptoms such as pain, swelling, a bad taste or difficulty opening the mouth develop, the assessment is repeated.
A decision to monitor is not permanent; it is revisited as the condition of the tooth and the surrounding tissues changes. For frequently asked questions about wisdom teeth and other oral health topics, see our frequently asked questions page.
When should you have your wisdom teeth evaluated in Ankara?
If you have recurring pain at the back of your mouth, swollen gums, difficulty opening your mouth or a bad taste, or if you are considering orthodontic treatment, it is a good idea to have your wisdom teeth assessed with an examination and X-ray. At our polyclinic in Oran, Çankaya, we examine the position of your wisdom teeth and their effect on the surrounding tissues, and explain to you, with our reasons, whether extraction or monitoring is the better option.
Frequently asked questions
Is it mandatory to remove wisdom teeth?
No. Wisdom teeth that are fully erupted, can be kept clean and cause no problems can stay in the mouth. Extraction is recommended when there are specific reasons such as recurring inflammation, decay that cannot be treated, damage to the neighboring tooth or the requirements of a treatment plan.
Do wisdom teeth cause crowding of the front teeth?
Current scientific evidence shows that wisdom teeth are not the only or the main cause of crowding in the front teeth. Teeth shifting over time depends on many factors. After orthodontic treatment, the main way to keep teeth in position is wearing a retainer.
What if an impacted wisdom tooth never causes any problems?
Impacted wisdom teeth that cause no symptoms and show no signs of disease can be monitored with regular examinations and X-rays at appropriate intervals. If a problem appears during monitoring, the decision to extract is reconsidered.
Should wisdom teeth be removed before clear aligner treatment?
Not in every case. The orthodontist decides based on the treatment plan and the position of the wisdom teeth. Extraction may be recommended if moving the back teeth backward is planned or if there is a problem with the wisdom tooth.
