Wisdom teeth, also known as third molars, are teeth that cause uncertainty, discomfort, and fear for many people. While some never experience any problems, for others wisdom teeth become a source of persistent pain, inflammation, and recurring dental complications. The reasons lie in their late eruption, limited space in the jaw, and their often irregular position. That is why it is important to understand when pain is temporary and harmless, and when it signals a condition that requires intervention.
This topic is especially relevant for adult patients because wisdom teeth most commonly begin to appear between late adolescence and the early thirties, often at a stage of life when tooth development is expected to be complete. Timely information helps patients make rational decisions, reduces fear, and enables safer treatment planning.
What are wisdom teeth and why do they often cause problems?
Wisdom teeth, known as third molars, are the last teeth to erupt in the dental arch. They are located at the very back of the upper and lower jaws, and they usually emerge between the ages of 17 and 25, although they may erupt much later — or not appear at all. Most people have up to four wisdom teeth, but it is not uncommon for one or more never to develop, which is now considered entirely normal.
The reason wisdom teeth often cause problems lies in evolutionary changes to the human jaw. Our ancestors had broader, stronger jaws and a diet that required intense chewing. In those conditions, wisdom teeth had a clear function. Modern diets and jaw development have led to many people simply not having enough space for wisdom teeth to be positioned correctly.
When a wisdom tooth does not have enough room to erupt, it may appear only partially, at an abnormal angle, or remain completely trapped in the bone. Such teeth are called impacted wisdom teeth. They can press on neighbouring teeth, cause pain, a feeling of tightness in the jaw, or lead to tooth movement. Partially erupted wisdom teeth are additionally problematic because they create a pocket between the tooth and the gum, where bacteria and food debris can easily accumulate.
Because of their position, wisdom teeth are often difficult to clean thoroughly, even with good oral hygiene. This increases the risk of tooth decay, gum inflammation (pericoronitis), bad breath, and recurring infections. Inflammation can spread to surrounding tissues, cause swelling, make it difficult to open the mouth, and even trigger pain that radiates towards the ear or temple.
It is important to emphasise that wisdom teeth do not always cause problems. If they erupt properly, sit in a good position, and can be kept clean, they often do not require any procedure. However, due to the high frequency of complications, wisdom teeth are among the most common reasons for surgical extraction in dental practice. That is why regular check-ups and timely assessment of wisdom tooth position play a key role in preventing more serious issues.
When is wisdom tooth pain normal, and when is it a sign of a problem?
Mild discomfort or occasional sensitivity in the area of the back teeth can be part of the normal process of wisdom tooth eruption. This pain is usually mild, appears intermittently, and does not persist continuously. It is most often felt as pressure in the jaw or slight gum tenderness, especially when chewing or touching the area. In these situations there is usually no significant swelling, fever, or pronounced redness of the surrounding tissue, and symptoms often resolve on their own within a short time.
A problem arises when the pain becomes intense, lasts for a long time, or worsens over time instead of improving. One of the most common causes of this type of pain is pericoronitis — inflammation of the soft tissue covering a partially erupted wisdom tooth. Because cleaning is difficult, bacteria and food debris are easily trapped there, triggering an inflammatory response. In such cases, pain is often accompanied by gum swelling, redness, an unpleasant taste in the mouth, bad breath, and difficulty opening the mouth.
In addition to pericoronitis, wisdom tooth pain may result from tooth decay developing on the wisdom tooth itself or on the neighbouring tooth. Because the area is hard to access, decay is often not noticed in time, and pain may radiate towards the ear, temple, or down the jaw. In some cases, pressure from an impacted wisdom tooth can cause pain and damage to the adjacent tooth, including root resorption or tooth movement within the dental arch.
Signs that suggest the pain is not temporary and requires a dental examination include:
• pain that lasts for several days and does not settle
• pain that worsens over time
• swelling of the face or gums
• difficulty opening the mouth or swallowing
• an unpleasant smell or taste in the mouth
• pain that radiates towards the ear, neck, or temple
It is important to emphasise that ignoring these symptoms can lead to inflammation spreading to surrounding tissues and, in some cases, to more serious complications. A timely examination allows assessment of the wisdom tooth position, the condition of the surrounding tissue, and a decision on next steps — whether that means monitoring, treatment, or a recommendation for extraction.
When should a wisdom tooth be removed, and when should it not?
There is no universal rule that all wisdom teeth must be removed preventively. The decision to remove them is based on a combination of clinical findings, X-ray imaging, and the symptoms a patient has — or may potentially develop. If a wisdom tooth has fully erupted, is correctly positioned in the dental arch, participates in chewing, causes no pain or inflammatory changes, and can be cleaned adequately, it usually does not require intervention. In such cases, the focus is on regular check-ups and maintaining thorough oral hygiene, because the situation can change over time.
Extraction is recommended when a wisdom tooth causes recurring pain, gum or surrounding tissue inflammation, bad breath, difficulty opening the mouth, or when it is associated with tooth decay that cannot be treated properly. A common reason for extraction is pericoronitis — recurrent inflammation of the soft tissue around a partially erupted wisdom tooth, which may settle with treatment but often returns because the underlying cause is mechanical and anatomical.
A separate group includes retained or impacted wisdom teeth that sit partially or completely within the bone. Although they may sometimes cause no immediate symptoms, these teeth can present a long-term risk because they may lead to cyst formation, resorption of the adjacent tooth’s root, chronic inflammation, or pressure on a nerve. For that reason, preventive extraction is recommended in certain situations, before complications develop and make the procedure more complex.
In orthodontic patients, wisdom teeth are sometimes removed as part of a wider treatment plan, particularly if there is a risk that later growth could affect the stability of the achieved tooth position. It is important to stress that this decision is never made routinely, but only on an individual basis after a detailed assessment.
What does wisdom tooth extraction involve?
The method of wisdom tooth extraction depends primarily on its position, how far it has erupted, and its relationship to surrounding structures. If a wisdom tooth has fully erupted and is in a correct position, extraction is usually a straightforward procedure, very similar to removing any other tooth. It is performed under local anaesthetic, the patient does not feel pain during the procedure, and the process is relatively quick.
Surgical extraction is needed when a wisdom tooth is partially or fully trapped in the bone, tilted towards the neighbouring tooth, or covered by gum tissue. In that case, the dentist or oral surgeon makes a small incision in the gum, removes a portion of bone if necessary, and extracts the tooth either whole or in smaller sections. Although the term “surgical extraction” often triggers anxiety, it is important to emphasise that this procedure is also performed under local anaesthetic and is painless during the operation itself.
Discomfort typically appears only after the anaesthetic wears off, but in most cases it can be effectively managed with the prescribed therapy. Many patients are surprised by how short the procedure is and how much less unpleasant it feels than expected, especially when carried out in controlled conditions and with good preparation.
What does recovery look like after wisdom tooth extraction?
Recovery after wisdom tooth extraction varies from person to person and depends on the complexity of the procedure, the tooth position, the patient’s general health, and how carefully postoperative instructions are followed. In the first hours after the procedure, mild bleeding is normal and stops once a blood clot forms in the socket. That clot is essential for healing and needs to be protected.
During the first two to three days, swelling, a feeling of tightness, and moderate pain can be expected. Swelling is usually most pronounced on the second or third day and then gradually subsides. Pain is generally well controlled with analgesics recommended by the dentist, and the need for stronger medication rarely lasts longer than a few days.
During the recovery period, it is important to avoid rinsing the mouth for the first 24 hours, as well as smoking and alcohol consumption, because all of these factors can interfere with healing and increase the risk of complications such as dry socket. A soft, lukewarm diet is recommended, along with adequate fluid intake and maintaining oral hygiene while cleaning the surgical area carefully and gently.
Most patients return to everyday activities within a few days, while complete tissue regeneration takes a little longer. Regular follow-up and adherence to the dentist’s instructions are key to a smooth and fast recovery without unpleasant surprises.
What is normal, and when should you contact your dentist?
Some discomfort is part of normal healing, but there are situations that require additional attention. If pain suddenly worsens a few days after the procedure, especially if accompanied by an unpleasant smell or taste in the mouth, it may indicate dry socket. This occurs when the blood clot is lost too early, leaving the bone exposed.
A raised temperature, pronounced swelling that does not go down, or increasing difficulty opening the mouth are also signs for which a follow-up examination is recommended. Prompt action helps prevent more serious complications and speeds up recovery.
Can wisdom tooth pain be prevented?
Although not all wisdom tooth problems can be prevented, regular dental check-ups allow early identification of potential risks. Radiographs help assess the position of wisdom teeth and plan possible extraction at the optimal time, often before symptoms develop.
Maintaining good oral hygiene, especially at the back of the mouth, reduces the risk of inflammation and tooth decay. For partially erupted wisdom teeth, extra attention to cleaning can significantly reduce how often problems occur.
Understanding wisdom teeth makes decision-making easier
Wisdom teeth are not necessarily problematic, but because of their position and the way they erupt, they often require extra attention. The difference between temporary discomfort and a serious problem is not always obvious, which is why it is important to listen to your body and not delay an examination if symptoms appear.
An informed patient finds it easier to decide on treatment, feels less fear about the procedure, and has more realistic expectations about recovery. Timely advice from a dentist and an individual approach are key to preserving oral health and avoiding unnecessary complications.
