All about wisdom teeth: why they hurt and when removal is needed

The wisdom tooth is one of the most talked-about teeth. It is surrounded by myths, fears and conflicting advice. Some believe a wisdom tooth should be removed as soon as it appears, while others live with theirs for years without any problems.

In reality, there is no universal rule. Each wisdom tooth has its own position, root shape and conditions for eruption. That is why it is important to understand what is happening in your particular case.

In this article, we will look at what a wisdom tooth looks like and how many a person can have. We will explain at what age wisdom teeth come in and why they cause pain. We will also cover pericoronitis, indications for removal and recovery after surgery.

What is a wisdom tooth and where is it located

A wisdom tooth is the third molar, located at the very end of the dental arch. It can be in the upper or lower jaw. In theory, a person has room for four wisdom teeth: one on each side, top and bottom.

However, not everyone has four wisdom teeth. The buds of some wisdom teeth may never form. So the answer to how many wisdom teeth a person has can vary. Some people have four, some have one or two, and in some cases wisdom teeth are absent altogether.

Another common question is what a wisdom tooth looks like. On the outside, it resembles the other chewing teeth, but its shape can vary greatly. The crown is sometimes irregular, and the roots may be curved or fused.

An X-ray shows the dentist much more. It makes it possible to assess the direction of growth, the depth of the tooth, the shape of the roots and the distance to the neighboring tooth. For the lower jaw, the proximity of important nerve structures also matters.

At what age do wisdom teeth come in and until what age does eruption continue

At what age wisdom teeth come in is a question without a single exact answer. The first signs of eruption most often appear around the age of 17-25. However, the process can begin earlier or much later.

Until what age wisdom teeth keep growing cannot be pinned to one age either. In some people, a wisdom tooth starts moving at a young age but erupts gradually. In others, the tooth remains impacted and never fully comes through.

Growth can happen in phases: first a small part of the crown appears, then the process stops, and months or even years later the wisdom tooth starts growing again. So age alone does not show whether there will be a problem – the position of the wisdom tooth and the available space matter much more.

Why wisdom teeth erupt with complications – anatomical reasons

The main problem with a wisdom tooth is often not its structure but a lack of space. The wisdom tooth comes in last, so the jaw may already be fully occupied by other teeth. Because of this, it starts growing at an angle or remains partially in the bone. It may tilt forward and press against the neighboring molar. Another option is a tilt backward or toward the cheek. Sometimes the wisdom tooth lies almost horizontally.

The shape of the jaw and roots also affects the process, so even two people of the same age can have completely different situations. An X-ray examination helps understand exactly how the wisdom tooth is growing and whether it poses a risk to the surrounding tissues. This is especially useful before severe pain appears.

How to tell if your wisdom tooth hurts – symptoms and how it differs from other pain

Pain in the back of the jaw does not always mean the problem is the wisdom tooth. Similar symptoms can be caused by:

• a neighboring tooth;
• gum inflammation;
• the temporomandibular joint;
• even the ear.

So how can you tell if your wisdom tooth hurts? Pay attention to where the discomfort is. With problematic eruption, pain is often felt at the very back of the jaw. It may radiate to the ear, temple, cheek or throat. The gum over the wisdom tooth may swell. Sometimes it hurts to chew or open your mouth wide. An unpleasant taste or smell may appear in the mouth.

An ear infection is more often accompanied by ear symptoms. With TMJ problems, pain may occur when moving the jaw and be accompanied by clicking or tension in the chewing muscles. A neighboring tooth can also be the source of pain. For example, decay or pulp inflammation can cause a reaction to cold, heat or biting.

It is difficult to determine the exact cause on your own. The dentist evaluates the symptoms, examines the area and orders an X-ray if needed.

Pericoronitis – what it is and why the gum flap over a wisdom tooth becomes inflamed

Pericoronitis is inflammation of the soft tissues around a partially erupted wisdom tooth. It most often occurs when part of the crown has already come through while the rest remains under the gum. A so-called gum flap (operculum) forms over the wisdom tooth, and food debris and bacteria easily get trapped beneath it. It is often hard to clean this area properly with a regular toothbrush.

At first, pericoronitis may show up as localized pain and redness. Then the gum swells, and discomfort increases when chewing. With severe inflammation, it becomes difficult to open the mouth. Recurrent pericoronitis often indicates that the wisdom tooth lacks space for normal eruption. In this situation, the dentist assesses whether it makes sense to keep the tooth.

Fever and swelling during wisdom tooth eruption – when it is normal and when it is dangerous

During wisdom tooth eruption, the gum may be sensitive. Slight local swelling is also possible. However, severe pain and pronounced swelling should not automatically be considered a normal part of growth.

Fever, pus discharge, an unpleasant smell, rapidly increasing swelling or a general feeling of being unwell may indicate an infection. Special attention is needed when a person cannot open their mouth normally or swallow. Swelling that quickly spreads to the face or neck requires urgent medical care.

Pericoronitis – the most common wisdom tooth complication

Pericoronitis develops due to inflammation of the tissues around a partially erupted molar. A closed space forms under the gum flap, where bacteria and food debris accumulate. As a result, the gum becomes red and swollen. Pain may spread to the cheek, ear or temple. In more severe cases, body temperature rises.

Pericoronitis is dangerous because the inflammation can spread beyond the wisdom tooth area. So with pronounced symptoms, home rinses alone are not enough.

How pericoronitis is treated – gum flap removal or tooth extraction

The treatment approach depends on why the inflammation occurred and how the wisdom tooth is positioned. First, the dentist assesses the condition of the mucosa and the wisdom tooth itself, and the inflamed area is cleaned and treated. In some cases, the gum flap is incised or removed. This option may be appropriate when the wisdom tooth has enough room to erupt fully.

If the wisdom tooth is poorly positioned, the inflammation may keep coming back. In that case, extraction eliminates the cause of constant injury and bacterial buildup. However, the decision is made after an examination, since the presence of a gum flap alone does not mean the wisdom tooth must be removed immediately.

Why untreated pericoronitis is dangerous – complications and consequences

Without treatment, pericoronitis can develop into a more severe inflammatory process. Swelling may spread to neighboring tissues, pain increases, and pus or an unpleasant smell appears. Limited mouth opening also becomes a problem – it is hard to eat, speak and keep up oral hygiene normally. Pericoronitis with a high fever or significant swelling requires prompt examination.

Do wisdom teeth have to be removed – when they can be kept

Whether wisdom teeth have to be removed is a question almost every patient asks before seeing an oral surgeon. The answer depends on the condition of the specific molar. A healthy wisdom tooth does not need to be removed simply because it is there. It can be kept if it grows straight, does not damage the neighboring tooth, takes part in chewing and does not cause hygiene problems.

Having an opposing tooth also matters. This means the wisdom tooth should be in contact with a molar in the opposite jaw. Without such contact, it may gradually shift and become harder to clean.

You also need to be able to reach it with a toothbrush. A hard-to-reach wisdom tooth tends to accumulate more plaque, which increases the risk of decay and gum inflammation. So the answer to the question of removal depends not on age or the fact of eruption, but on the condition of the wisdom tooth and the surrounding tissues.

When a wisdom tooth must be removed – clear indications

Wisdom tooth removal is recommended for recurrent pericoronitis, significant crown destruction or when decay cannot be treated properly. Damage to the neighboring molar can be another indication. Surgery is also considered when the tooth is abnormally positioned. For example, a wisdom tooth may press on the neighboring molar or create conditions for a cyst to form.

Indications are determined individually. Even an impacted wisdom tooth does not always require immediate surgery. Its position, the patient’s age, bone condition and the presence of pathological changes all matter.

Impacted and malpositioned wisdom teeth – how they differ and what to do about them

An impacted wisdom tooth has not fully erupted, so it may remain under the gum or deep in the bone. Part of the crown is sometimes still visible.

A malpositioned wisdom tooth is in the wrong position. It may be tilted toward the neighboring molar, rotated around its axis or lying almost horizontally. Such teeth do not always hurt, and the problem may develop gradually. For example, the molar presses on the neighboring tooth or creates a space where bacteria accumulate.

The decision is made after analyzing the X-ray. The dentist assesses the roots, the direction of growth and the proximity to important anatomical structures.

How wisdom teeth are removed – simple and surgical extraction

How a wisdom tooth is removed depends on its position. A fully erupted wisdom tooth can often be removed relatively easily – the dentist administers anesthesia, checks that the area is numb and carefully lifts the wisdom tooth out of the socket.

An impacted or horizontal molar is more difficult to remove. In this situation, access to the bone may be needed. The wisdom tooth is sometimes sectioned into parts so it can be removed without excessive stress on the surrounding tissues. Modern local anesthesia makes the procedure painless during surgery. The patient may feel pressure, movement or vibration, but sharp pain is not a normal part of the procedure.

How wisdom tooth removal works – step by step from anesthesia to stitches

First, the surgeon examines the mouth and reviews a panoramic X-ray. Additional diagnostics are done if needed. Then local anesthesia is administered – the dentist checks that the area is numb enough.

In a simple extraction, the wisdom tooth is carefully lifted out of the socket. In a surgical extraction, the dentist may make a small incision, remove some bone or section the crown and roots. After removal, the socket is cleaned and stitches are placed if needed. A gauze pad is placed on the area to help a blood clot form.

How long pain and swelling last after wisdom tooth removal – what is normal and warning signs

Once the anesthesia wears off, pain appears, but it is usually moderate and gradually subsides. After a surgical extraction, the discomfort may be stronger. Swelling often increases over the first 2-3 days and then gradually goes down. Bruising on the skin is also possible, especially after a complex procedure.

A different picture is a cause for concern: the condition first improved, and then the pain sharply worsened. Fever, pus, a strong unpleasant smell or increasing swelling also require an examination.

After wisdom tooth removal – aftercare and recovery

After surgery, a blood clot forms in the socket. It protects the tissues and creates the conditions for healing, so in the first hours the main thing is not to disturb it. During the first day, avoid vigorous rinsing and do not touch the socket with your fingers or tongue. You can apply cold to your cheek through a cloth in short intervals.

Food should be soft and not hot, and it is better to chew on the opposite side. Painkillers should only be taken as recommended by your dentist.

In the following days, the dentist may prescribe antiseptic care. Rinse your mouth gently, without moving the liquid vigorously. Stitches may be dissolvable or may need to be removed – the timing depends on the material and the complexity of the surgery.

Dry socket after wisdom tooth removal – symptoms and what to do

Dry socket (alveolar osteitis) is inflammation of the socket after extraction, and it is often associated with the loss of or damage to the blood clot. A typical symptom is pain that does not ease after a few days but gets stronger. It may radiate to the ear, temple or a nearby area of the jaw. An unpleasant smell or taste may also appear. The socket looks unusual, and regular painkillers provide little relief.

If you suspect dry socket, see a dentist. The dentist cleans and treats the socket and then determines further care.

What not to do after wisdom tooth removal – the full list of restrictions

The first few days are needed for undisturbed healing, so it is worth following a few simple restrictions after surgery. It is not recommended to:

• rinse vigorously during the first day;
• touch the socket with your fingers or tongue;
• drink through a straw;
• eat very hot food;
• smoke;
• drink alcohol;
• do intense physical exercise right after surgery.

These actions can damage the blood clot or increase bleeding. Specific recommendations depend on the complexity of the procedure and the patient’s condition.

Wisdom tooth removal at DDC dental clinic – book an appointment

At Digital Dental Clinic, treatment begins with a consultation and diagnostics. A panoramic X-ray makes it possible to assess the position of the wisdom tooth, its direction of growth and its relation to neighboring structures. After the examination, the dentist explains whether the wisdom tooth needs to be removed and how complex the procedure will be. The patient receives information about anesthesia, the course of the surgery and recovery.

In a simple extraction, the procedure is performed without significant tissue trauma. Surgical removal requires more detailed planning, especially when the wisdom tooth is impacted or horizontal.

After surgery, the dentist gives recommendations on diet, hygiene and symptom monitoring. A follow-up visit is scheduled if needed.

Not every wisdom tooth needs to be removed. But pain, recurrent pericoronitis, damage to the neighboring tooth or an unfavorable position should not be ignored. A consultation will help you understand whether surgery is needed in your case.

FAQ:

How many wisdom teeth can a person have and do they always have four?

A person can have a maximum of four wisdom teeth. However, the number varies – some people develop one or two wisdom teeth, while others have no buds at all.

At what age do wisdom teeth usually come in?

Wisdom teeth most often start to erupt between the ages of 17 and 25. However, the exact timing depends on each person’s anatomy. Some wisdom teeth may remain in the bone for life.

Do you have to remove a wisdom tooth if it doesn’t hurt?

No. But the absence of pain is no guarantee that everything is fine. A properly positioned molar that can be cleaned well and does not damage the surrounding tissues can often be kept.

How long does the cheek hurt and stay swollen after wisdom tooth removal?

Swelling usually peaks on day 2 or 3 and then gradually decreases. Moderate pain during this period is an expected reaction. A sharp worsening of symptoms after improvement requires an examination.

What is pericoronitis and does it always require tooth removal?

Pericoronitis is inflammation of the tissues around a partially erupted molar. Not every case requires extraction. The dentist assesses the position of the wisdom tooth, how often the inflammation recurs and whether proper hygiene is possible. With frequent flare-ups, surgery may be the most predictable option.
