When Should Impacted Wisdom Teeth Be Extracted?

Impacted wisdom teeth should be extracted without delay when they lack sufficient space in the jawbone, causing pain, infection, or decay in adjacent teeth. While healthy wisdom teeth that erupt properly and do not harm surrounding tissues do not need to be removed, severe wisdom tooth pain and recurrent swelling in the gums indicate a clear need for surgical intervention. If you are experiencing such symptoms, an evaluation by a specialist can prevent future cysts or permanent jaw damage.

In Brief

• Wisdom teeth typically begin to emerge between the ages of 17 and 25.
• A lack of space in the jaw causes the tooth to remain impacted under the bone or gum tissue.
• The most common symptoms include pain at the corner of the jaw, aching that radiates to the ears, and bad breath.
• Diagnosis usually involves a panoramic X-ray or three-dimensional cone beam computed tomography (CBCT).
• The extraction can be performed under local anaesthesia, though general anaesthesia may be preferred for patient comfort.
• Depending on the extent of the surgery, the recovery process is usually complete within 3 to 7 days.

What is an Impacted Wisdom Tooth?

The last teeth to erupt in an adult's mouth are the third molars, commonly known as wisdom teeth. Most people have four in total, located at the very back of the upper and lower jaws. They generally try to emerge into the oral cavity between the ages of 17 and 25. However, because the human jaw tends to be smaller due to changing dietary habits, these teeth often cannot find enough space to erupt.

Teeth that cannot find adequate space remain trapped inside the jawbone or under the gum tissue, in a fully or partially impacted position. While fully impacted teeth are entirely invisible from the outside, only a small portion of partially impacted teeth pierces the gum to reach the inside of the mouth. The flap of gum tissue surrounding partially impacted teeth creates an ideal environment for food particles to accumulate and bacteria to multiply.

This situation paves the way for the tooth itself to decay or for an infection to develop in the surrounding tissues. Impacted teeth can sometimes remain in the jawbone for years without causing any complaints. However, they often put pressure on adjacent teeth, causing structural problems, and require surgical removal.

Causes and Risk Factors for Impacted Wisdom Teeth

The primary reason wisdom teeth remain impacted is the lack of sufficient space in the jawbone to accommodate them. Genetic factors are the most significant determinant of the mismatch between jaw size and tooth size. Individuals with a family history of impacted teeth are highly likely to face a similar situation.

In addition, the premature loss of primary (baby) teeth during childhood or the eruption of permanent teeth at an abnormal angle can block the path of wisdom teeth. In individuals with narrow jaws, the back teeth shift forward, narrowing the space where the wisdom tooth would emerge. Furthermore, childhood habits that negatively affect jaw development, such as mouth breathing or thumb sucking, are also considered risk factors that lead to jaw narrowness in later years.

Changes in dietary habits—such as shifting away from the hearty, chew-intensive fresh produce and meats typical of traditional Turkish cuisine towards softer, modern processed foods—also contribute to the underdevelopment of jaw muscles and bones. Jaws that do not receive enough chewing force remain underdeveloped, leaving the last erupting teeth with no space and dooming them to an impacted position.

What Are the Symptoms of an Impacted Wisdom Tooth?

Fully or partially impacted teeth may not always show immediate symptoms. However, as the tooth tries to erupt or an infection develops around it, some typical complaints arise. The severity of the symptoms varies depending on the tooth's position and the pressure it exerts on surrounding tissues. A condition called pericoronitis (gum inflammation) is particularly common around partially impacted teeth.

The most common symptoms include:

• Throbbing pain at the corner of the jaw that radiates towards the ear and neck.
• Redness, swelling, and tenderness in the gum tissue of the affected area.
• Difficulty opening the mouth and severe aching while chewing.
• Persistent bad breath despite brushing, and a bad taste in the mouth.
• Swelling and tenderness to the touch in the lymph nodes under the jaw.

Food particles accumulating around partially impacted teeth can also cause the adjacent healthy tooth to decay. Sometimes, when these cavities are combined with conditions that strain the jaw joint, such as teeth grinding during sleep (bruxism), the intensity of the pain is felt much more severely. When these symptoms begin, it indicates that the tooth has started to damage the surrounding tissues.

How is it Diagnosed at the Hospital?

When you visit the hospital complaining of an impacted tooth, your dentist will first perform a detailed intraoral examination. During this exam, swelling and redness in the gums, potential decay in the adjacent tooth, and your ability to open your mouth are evaluated. However, radiological imaging is essential to see the exact position of the impacted teeth, their root structure, and their relationship with surrounding anatomical formations.

The most commonly used method in the diagnostic process is a panoramic X-ray. A panoramic X-ray shows the entire upper and lower jaws, teeth, and jaw joints on a single film. This makes it possible to clearly determine the angle of the impacted tooth, its depth within the bone, and its distance from adjacent teeth.

In complex cases where the tooth is very close to the main nerve passing through the lower jaw or where a cyst is suspected, a three-dimensional dental tomography (CBCT) is requested. Tomography shows the tooth's relationship with the nerve down to the millimetre, allowing surgical planning to be done much more safely. This 3D imaging is vital to reduce the risk of nerve damage to zero.

Impacted Tooth Extraction Treatment with Oral Surgery

The treatment of impacted teeth is a surgical extraction procedure planned according to the condition of the tooth. The operation is usually performed under local anaesthesia, numbing only the relevant area. However, for highly anxious patients, those with a strong gag reflex, or cases where multiple impacted teeth will be extracted at the same time, sedation or general anaesthesia may be preferred.

During the extraction, the oral and maxillofacial surgeon opens the gum over the tooth with a small incision. If the tooth is embedded in the bone, a small amount of the overlying bone tissue is removed using special instruments to access the tooth. Sometimes, extracting the tooth in one piece could damage surrounding tissues, so the tooth is divided into several pieces and removed. Once the extraction is complete, the area is cleaned, and the gum is closed with stitches.

The surgical procedure typically takes between 20 and 45 minutes. Mild swelling and pain are expected during the first few days of the recovery period. Painkillers and antibiotics prescribed by your doctor will help you get through this process comfortably. To avoid disrupting blood clot formation in the extraction site, refraining from using straws, avoiding smoking, and staying away from hot foods and drinks directly affects the speed of healing. For instance, sipping a piping hot glass of Turkish tea too soon can dissolve the protective blood clot and delay recovery. Stitches are usually removed after about a week, or if self-dissolving stitches were used, the tissue heals rapidly on its own.

Complications of Untreated Impacted Teeth

Impacted teeth that cause problems and are not treated in time lead to complications that seriously threaten oral health. The most common problem is the inflammation of the gum surrounding a partially impacted tooth. If left untreated, this inflammation can spread to the cheek and neck area, turning into severe abscesses.

Another significant complication is the mechanical pressure the impacted tooth exerts on the second molar directly in front of it. This pressure causes the roots of the healthy adjacent tooth to resorb or deep cavities to form on the contact surface. As the decay progresses, the healthy tooth may also require root canal treatment or even complete extraction.

Furthermore, the protective sac around impacted teeth can fill with fluid over time, turning into cysts or, rarely, tumours. The resulting cysts cause bone loss in the jaw, weakening the bone and paving the way for jaw fractures from even the slightest trauma. Crowding of the front teeth in the lower jaw is another aesthetic and orthodontic problem caused by the pressure coming from the back.

When to See a Doctor?

During the eruption period of wisdom teeth, between the ages of 17 and 25, it is recommended to undergo a routine dental check-up even if you have no complaints. However, certain symptoms require you to visit a healthcare facility without waiting. Early intervention prevents the infection from spreading to surrounding tissues.

If you experience any of the following symptoms, you should consult your doctor without delay:

• Severe toothache that wakes you from sleep and does not subside despite painkillers.
• Noticeable swelling on the outside of the cheek, under the jaw, or in the neck.
• Significant difficulty in opening your mouth, chewing, or swallowing.
• Pus discharge from the gums or a sudden bad taste in the mouth.
• High fever or chills accompanying the pain and swelling.

If your difficulty swallowing is very severe, if you are having trouble breathing, or if the swelling has progressed up to your eye, the infection may have entered your bloodstream or narrowed your airway. Since this requires emergency medical intervention, you should immediately call 112 or visit the nearest hospital emergency room.

Frequently Asked Questions

How long does an impacted wisdom tooth extraction take?

The duration of an impacted tooth operation varies depending on the tooth's position in the bone, its root structure, and its angle. A standard surgical extraction is usually completed between 20 and 45 minutes. This time may be slightly longer for deeply impacted teeth or those associated with a cyst.

How can I relieve wisdom tooth pain at home?

Methods you apply at home will not solve the tooth's underlying problem, but they can alleviate the pain until you see a dentist. Gargling with warm salt water, applying a cold compress to the outside of the cheek, and using over-the-counter painkillers recommended by your doctor provide temporary relief. A surgical evaluation is absolutely necessary for a permanent solution.

Must every impacted wisdom tooth be extracted?

No, it is not mandatory to extract every impacted tooth. If the tooth remains completely inside the bone, does not harm adjacent teeth, carries no risk of forming a cyst, and does not cause any pain, it can simply be monitored with regular X-ray follow-ups. The decision to extract is based on the tooth's current or potential risk of causing harm.

When does facial swelling go down after extraction?

Swelling in the cheek after a surgical procedure is an expected outcome, depending on the difficulty of the operation. The swelling usually peaks on the second or third day, then slowly begins to subside. On average, your face will return to its completely normal appearance within 5 to 7 days.

Is impacted tooth surgery difficult?

Because it is performed under local or general anaesthesia, you will not feel any pain or aching during the procedure. The post-operative period is quite comfortable with the use of antibiotics, painkillers, and mouthwashes prescribed by your doctor. Thanks to modern surgical techniques, impacted tooth extractions are now performed much more safely and comfortably.
