Wisdom teeth are permanent teeth located at the very back of the dental arch and are known as “third molars.” Commonly referred to as wisdom teeth or “twenties” in everyday language, these teeth typically begin to erupt during young adulthood. However, contrary to their name, not every wisdom tooth erupts exactly at age 20. In some people, they may erupt earlier or later; in others, they may remain embedded in the jawbone without ever emerging into the mouth.
The eruption of wisdom teeth does not occur the same way in everyone. If there is sufficient space in the jaw, the tooth can erupt into its normal position and remain in the mouth without causing any problems. In cases where there is insufficient space, the tooth may erupt only partially, tilt toward an adjacent tooth, or remain completely embedded within the jawbone.
Especially with partially erupted or impacted wisdom teeth, pain, swelling, and infection can develop around the gums. The difficulty in cleaning the tooth due to its position can also set the stage for cavities and gum problems.
For this reason, the mere fact that a wisdom tooth has “erupted” does not necessarily mean it needs to be extracted. The dentist evaluates the tooth’s position, the surrounding tissues, its relationship with adjacent teeth, how easily it can be cleaned, and whether it is causing any symptoms in the patient.
When and Where Do Wisdom Teeth Erupt?
Wisdom teeth typically begin to erupt between the ages of 17 and 25. However, this age range is not a strict limit. In some people, they may erupt earlier, while in others, they may erupt even after the age of 25.
These teeth are located in the very back of the upper and lower jaws, behind the second molars. Because they are at the very end of the dental arch, whether there is sufficient space for them to erupt is crucial.
If there is sufficient space in the jawbone, a wisdom tooth can erupt into the mouth in a manner similar to other molars. However, when there is insufficient space, various complications may arise. The tooth:
- It may erupt completely into the mouth,
- Only a portion may emerge,
- It may remain beneath the gumline,
- It may remain embedded within the jawbone,
- It may be tilted toward the front molar.
The fact that a wisdom tooth is not visible in the mouth does not mean the person does not have it. An impacted wisdom tooth is often detected only through a dental examination and, if necessary, radiographic imaging.
What Are the Symptoms of a Wisdom Tooth?
A wisdom tooth that erupts without complications and in the correct position may not cause any symptoms. Complaints typically arise when the surrounding tissues are affected during eruption, when the tooth remains partially impacted, or when an infection develops.
Symptoms that may occur as a wisdom tooth erupts include the following:
- Pain or a feeling of pressure in the back of the jaw,
- Sensitivity in the gums,
- Redness or swelling around the wisdom tooth,
- Pain while chewing,
- Discomfort when opening the mouth,
- Pain radiating toward the jaw or ear,
- Bad taste in the mouth,
- Bad breath,
- Only part of the tooth is visible,
- Food buildup around the gums,
- Swelling in the surrounding tissues in the event of an infection.
Inflammation of the gum tissue around a wisdom tooth is called pericoronitis. Particularly in partially erupted lower wisdom teeth, bacteria and food debris can accumulate beneath the gum tissue that partially covers the tooth. This condition can cause pain, swelling, and difficulty opening the mouth.
If he experiences severe pain, rapidly increasing swelling of the face or jaw, fever, difficulty swallowing, or significant difficulty opening his mouth, he should not delay seeing a dentist.
Do Wisdom Teeth Come in for Everyone?
No. Wisdom teeth do not develop or erupt into the mouth in the same way for everyone.
While some people have four wisdom teeth, others may develop only one, two, or three. In some individuals, wisdom tooth buds may not form at all.
Another reason why a tooth may not be visible in the mouth even though it exists is that it is impacted. Due to the structure of the jawbone or the direction of the tooth’s eruption, the tooth may remain completely buried beneath the bone or gum tissue.
Therefore, the absence of a wisdom tooth in the mouth does not, by itself, indicate that the tooth is not present at all. When necessary, imaging methods such as panoramic X-rays can be used to assess the presence and location of the teeth.
How Many Days Does It Take for a Wisdom Tooth to Erupt?
It is not possible to give an exact number of days for a wisdom tooth to fully erupt. Tooth eruption is a process that varies from person to person and is often not completed in a single stage.
While the tooth may become visible within a few weeks or months in some people, the eruption process may continue intermittently in others. After part of the tooth has emerged into the mouth, its progress may pause for a while and then resume.
The available space in the jaw, the angle of the tooth, bone structure, and the tooth’s position in the mouth can all affect the duration of the eruption process.
Therefore, rather than asking, “How many days does it take for a wisdom tooth to come in?” it is more important to determine whether the tooth is moving into the correct position. Teeth that have remained partially erupted for a long time and repeatedly cause pain or infection should be evaluated by a dentist.
How Many Wisdom Teeth Are There?
In a standard dental structure, there may be four wisdom teeth. These are:
- One in the upper right jaw,
- One in the upper left jaw,
- One in the right lower jaw,
- and one in the lower left jaw
for a total of four third molars.
However, not everyone has four wisdom teeth. In some people, one or more of these teeth may fail to develop.
More rarely, a person may have more than the normal number of third molars or additional tooth structures. The number and position of the teeth can be assessed with a panoramic X-ray.
What Factors Affect the Eruption of Wisdom Teeth?
One of the most important factors determining how wisdom teeth erupt is whether there is sufficient space for them in the jawbone.
Some of the factors that can affect the eruption of wisdom teeth include:
Jaw structure: Insufficient space in the back of the jaw may prevent the tooth from fully erupting.
Angle of eruption: The tooth may erupt in an upright position or develop at an angle—toward the front, back, or side.
Position of adjacent teeth: The second molar can affect the space available for the wisdom tooth to erupt.
The tooth’s position within the bone: Some wisdom teeth are positioned deeper within the jawbone and cannot erupt into the mouth.
Individual developmental differences: The timing of tooth development and eruption can vary among individuals.
Assessing the eruption status of a tooth based solely on the visible portion in the mouth may not always be sufficient. When necessary, radiographic imaging can provide more detailed information about the tooth’s root structure and its relationship with adjacent anatomical structures.
What Causes Wisdom Tooth Pain?
There can be various causes of wisdom tooth pain. Pressure and sensitivity in the surrounding gum tissue during tooth eruption can cause short-term pain. However, severe or persistent pain may indicate an underlying problem.
One of the most common causes of wisdom tooth pain is when the tooth only partially erupts into the mouth. Inflammation can develop when food particles and bacteria accumulate beneath the gum tissue covering the tooth. In this condition, known as pericoronitis, pain may be accompanied by swelling and a bad taste in the mouth.
Other possible causes of pain include:
- Tooth decay in the wisdom tooth,
- Cavities developing in the adjacent second molar,
- A gum infection,
- Pressure from the tooth on an adjacent tooth,
- Infection in the tissues surrounding the tooth,
- Certain pathologies developing around an impacted tooth
may be present.
You may also feel the pain from a wisdom tooth radiating toward the ear, jaw, or the same side of the face. A clinical examination and, when necessary, radiographic evaluation are required to determine the actual cause of the pain.
How Can Wisdom Tooth Pain Be Relieved?
A permanent solution for wisdom tooth pain depends on identifying the cause of the pain. Home remedies may provide temporary relief but do not treat underlying issues such as infection, decay, or an impacted tooth.
It is important to keep the area clean during the period of pain. Brushing your teeth regularly and removing food debris accumulated around the wisdom tooth as much as possible supports oral hygiene.
If deemed appropriate by a dentist, medication may be used to manage the pain. However, antibiotics, in particular, should not be used without a dentist’s evaluation. Antibiotics are not necessary for every case of wisdom tooth pain.
Applying a cold compress to the outside of the cheek for a short time can provide relief, especially when there is swelling.
If the pain lasts longer than a few days, recurs repeatedly, or is accompanied by swelling, a bad taste, fever, or difficulty opening the mouth, he should see a dentist.
Applying chemicals, alcohol, aspirin, or similar products directly to the tooth at home is not recommended, as it can cause irritation to oral tissues.
When Should Wisdom Teeth Be Extracted?
Not every wisdom tooth needs to be extracted. A wisdom tooth that is properly positioned in the mouth, has fully erupted, can be cleaned, and does not damage surrounding tissues can be monitored.
The decision to extract a wisdom tooth is made based on a clinical examination and, when necessary, a radiographic evaluation.
Situations in which wisdom tooth extraction may be considered include:
- Recurrent gum infections,
- Untreatable or advanced tooth decay,
- Cavities or tissue damage in an adjacent tooth,
- A partially impacted tooth that cannot be cleaned and causes ongoing problems,
- The presence of a cyst or other pathological formations around the tooth,
- Damage to the periodontal tissues surrounding the tooth,
- Pain or infection caused by the tooth’s position
may be present.
Whether an asymptomatic impacted wisdom tooth should be extracted is evaluated on a case-by-case basis for each patient. The mere fact that a tooth is impacted does not, in and of itself, necessitate extraction in every case.
How Is a Wisdom Tooth Extraction Performed?
The method used to extract a wisdom tooth depends on its position in the mouth and within the jawbone.
Some fully erupted wisdom teeth in the correct position can be removed in a manner similar to a standard tooth extraction. The area is numbed with local anesthesia before the procedure, and the tooth is extracted using appropriate instruments.
If part or all of the tooth is embedded beneath the bone and gum tissue, surgical extraction may be necessary.
In a surgical extraction, generally:
- The area is numbed with local anesthesia.
- If necessary, access to the gum tissue is created.
- If there is bone covering the tooth, a controlled amount of bone may be removed.
- To facilitate removal, the tooth may be sectioned into pieces if necessary.
- After the tooth is extracted, the area is cleaned.
- If deemed necessary, the area is closed with stitches.
The duration and difficulty of the procedure may vary depending on the tooth’s position, root structure, and relationship to surrounding anatomical structures.
In Which Cases Is Surgery Performed?
Surgical extraction may be performed in cases where a wisdom tooth cannot be safely or easily removed using standard extraction methods.
Surgical extraction is particularly indicated when the tooth:
- is embedded within the jawbone,
- A portion of the tooth is located beneath the bone,
- is positioned horizontally or at a pronounced angle,
- It is tilted toward an adjacent tooth,
- The root structure making extraction difficult
may be considered in such cases.
When planning surgery, the tooth’s relationship to the surrounding anatomical structures is also taken into account. In particular, the relationship between the roots of the lower wisdom teeth and the nerve canal is one of the key points that must be evaluated during radiographic examination.
If deemed necessary, three-dimensional imaging methods may be used in addition to panoramic radiography.
What to Expect After Wisdom Tooth Extraction
Mild to moderate pain, tenderness, and swelling may occur in the first few days following wisdom tooth extraction. These symptoms may be more pronounced in surgical extractions than in simple extractions.
The blood clot that forms in the extraction site is an important part of the healing process. Therefore, the clot must be protected.
Initial Period:
- The gauze pad provided by the dentist should be kept in place for the specified duration,
- Do not probe the extraction site with your tongue or fingers,
- Very hot foods and beverages should be avoided in the first few hours,
- Do not chew hard foods on the side where the extraction was performed,
- The medications prescribed by the dentist should be taken as directed,
- You should avoid cigarettes and tobacco products.
Rinsing vigorously or spitting frequently within the first 24 hours may cause the blood clot to dislodge.
Swelling may occur in the days following the extraction. The course of the swelling may vary depending on the extent of the procedure.
If the pain increases significantly instead of subsiding after a few days, or if he experiences a bad taste or odor, persistent heavy bleeding, a fever, or progressively worsening swelling, he should contact his dentist.
A condition known as “alveolitis” or “dry socket,” which develops due to the loss of the blood clot, may be one of the causes of severe pain that becomes apparent a few days after the extraction.
