Wisdom Tooth Extraction: Indications, Procedure and Recovery

I am Dr. Solène Vo Quang, oral surgeon (medicine and oral surgery) at 7 rue Marbeau, 75016 Paris. In my practice, I often accompany patients for wisdom teeth, but also for oral infections, complex pains, and diagnostic help through imaging, sometimes in 3D.

My goal here is simple. Help you understand the situations where extraction is recommended, how I decide between monitoring and intervention, and how to recover well, without dramatizing, but without minimizing either.

Why is it sometimes necessary to pull out a wisdom tooth (third molar)?

The wisdom tooth, which is also called third molar, is the last tooth to come out. It often happens when the dental arcade, i.e. the space available on the jaw, no longer has much margin, and that's where the problems begin.

I don't get a wisdom tooth, by principle. I'm trying to link your symptoms, clinical examination, and images, to decide if the benefit of removing the tooth is greater than the risks and constraints of surgery.

Common signs: pain, swollen gum, infection (pericoronarite)

The most common signs are pain at the bottom of the jaw, swollen gum, sometimes red, and an obstacle to chewing. Some patients also describe bad breath or unpleasant taste, especially when the area is infected.

A classic scenario is that of the partially exited tooth, with a small gum capuchon on top. This cap easily retains food debris and bacteria, and can cause pericoronarite, i.e. inflammation, sometimes infected, of the tissues around the tooth.

When the infection settles down, you may feel a pain that radiates to the ear or throat, and sometimes a difficulty opening the mouth. In these situations, I also take into account your general condition, including fever or fatigue, as the mouth is never isolated from the rest of the body.

Causes: lack of space, tooth included/impacted, decay, cyst, orthodontic discomfort

The most common cause is lack of space. The tooth pushes from the cross, presses on the neighbouring molar, or stays stuck in the bones, so we talk about tooth included, or impacted, which means that it cannot get out properly.

There are also caries on the wisdom teeth, or on the tooth just ahead, because access to brushing is difficult. In the longer term, an impacted tooth may be associated with a cyst, i.e. a cavity filled with liquid that may weaken the body around.

Finally, some extractions are discussed in an orthodontic context. It is not an automatism, but a global reflection, especially if a wisdom tooth may hinder alignment or maintain chronic inflammation difficult to stabilize.

How to know if extraction is necessary: examinations and diagnosis

Patients often ask me if it is necessary to remove all wisdom teeth. The answer is nuanced, there are several approaches, each with its merits, and the right decision depends on your anatomy, your symptoms, and your medical history.

In my practice, I seek to make a precise diagnosis before speaking of avulsion, i.e. extraction. The aim is to avoid unnecessary interventions while not allowing a situation at risk of infection or complication to evolve.

Consultation and imaging (panoramic/CBCT): what the dentist is looking for

The consultation begins with an examination of the mouth, the gum, the mobility of the teeth, and your oral opening. I'm also interested in how you chew, how you pain, and what triggers or relieves the symptoms, as these details give a lot of direction.

Imaging is often indispensable. A panoramic X-ray gives an overview, and when the situation is complex, I can propose a CBCT, a 3D imaging, which allows to see the actual position of the tooth, the shape of the roots, and the bone environment.

An important point is the relationship with the inferior alveolar nerve, especially for the lower wisdom teeth. This nerve gives sensitivity to the lip and chin, and I check its proximity to the roots to choose the safest technique, and explain the risks transparently.

Cases of monitoring rather than extracting: when forbearance is possible

Surveillance is sometimes the best option, especially if the tooth is well positioned, accessible to brushing, without decay, and without infectious episode. In this case, I will explain to you what I am watching, and at what rate, to avoid the wisdom tooth.

One can also monitor an impacted tooth that causes no symptoms, provided there is no sign of cyst, resorption of the neighbouring tooth, or bone weakening. The decision is built over time, and must remain reversible, as long as the situation is stable.

Procedure: how is the wisdom tooth removal?

The apprehension is normal. Many patients imagine a long and painful procedure, while, well prepared, extraction often takes place in a simpler way than expected, even if the suites require a little care.

What changes everything is to understand if you are facing a simple extraction, on a tooth exit, or surgery, on a tooth included. The duration, the gestures, and the suites are not the same, and I prefer to tell you clearly before.

I always explain why and how, because understanding intervention often reassures more than words.

Simple extraction vs surgery: steps, duration, stitches

When the tooth is out and well accessible, extraction can be relatively direct, under local anesthesia, with a precise and controlled gesture. The duration is variable, but you often stay for a short time, with pressure felt, more than pain.

When the tooth is included or semi-included, we talk more about surgery. It may be necessary to clear the tooth in the bone, sometimes to cut it into several pieces, then clean the area before closing.

Suture stitches are used to replace the gum and promote clean healing. They can be resorbable, so they fall alone, or not resorbable, with a quick removal to the cabinet, depending on the situation and the quality of the tissues.

Local, sedative or general anesthesia: for whom and in which cases

In most cases, local anesthesia is sufficient. It sleeps the area, you stay conscious, and the goal is that you do not feel pain during the gesture, even if the feeling of manipulation exists.

Sedation, i.e., drug help to reduce anxiety, can be discussed if you are very stressed, if multiple teeth need to be removed, or if the procedure is longer. General anesthesia, however, is reserved for specific situations, after evaluation, as it requires a specific framework and an appropriate assessment.

I also take into account your medical background, treatment, and history. Tomorrow's medicine will not be built into silo, and a successful extraction begins with an overall vision, not just tooth.

After extraction: pain, swelling and recovery (day by day)

After extraction, moderate pain and swelling are normal. What I am trying to give you are concrete benchmarks, to distinguish a usual healing from a warning signal.

The mouth heals quickly, but it heals in a humid environment, and it is asked at every meal, every word. This explains why recovery is progressive, and why some simple gestures make a real difference.

Healing timeline: J0–J2, J3–J7, after 2 weeks (which is normal)

In the first 24 to 48 hours, mild bleeding or sooting is common and swelling may increase. Pain is often better controlled if you follow the prescription from the beginning, without waiting to be very embarrassed.

Between day three and day seven, most patients see a clear improvement. You can still have a limited mouth opening, what is called a trismus, and an embarrassment when chewing, but the trend must be downwards.

After two weeks, the gum is usually well closed, although it takes longer to remodel. A small local sensitivity may persist, and it is often at that time that you take a more varied diet, with more comfort.

Food, hygiene, sport and work: when to resume and what to avoid

In the first few days, I recommend warm or cold, rather soft foods and chew away from the area if possible. Very hot, very hard or very friable foods can irritate the wound or get caught, which keeps the inflammation going.

Hygiene remains essential, but it must be mild. You can brush your teeth the same evening, avoiding rubbing the area directly, and keeping a careful brushing on the rest of the mouth, as a clean mouth heals better.

For work and activities, it depends on the difficulty of intervention and your occupation. In general, I recommend avoiding intense sports in the first few days, as effort can promote bleeding and increase swelling, and gradually resume when pain decreases.

What to do at home (and what to avoid) after having a wisdom tooth removed

The quality of the suites depends heavily on small details. I prefer to give you simple benchmarks, so that you know what to do at home, and why some reflexes, though logical, can hinder healing.

The goal is to protect the clot, this little corkscrew that forms in the alveole, i.e. the hole left by the tooth. This clot is valuable because it serves as a basis for healing.

Pain relief: cold, rest, medicines (safety rules)

The external cold on the cheek, in short periods, often helps to limit swelling at the beginning. Rest and a slightly raised head position on the first night can also improve comfort.

I ask you to follow the prescription as drafted, and not to add anti-inflammatory drugs without notice, because they are not suitable for all medical situations. In my practice, I normally ask patients to rate the hour of each dose on the first day, as this avoids forgetfulness and double taking when you are tired.

Not to be done: rinses too early, straw, tobacco/vap, spitting, alcohol

Rinsing too early is a common cause of problem, even if you want to clean up. During the first 24 hours, flushing vigorously can dislodge the clot and increase the risk of alveolite, a very painful inflammation of alveole.

Straw, strong spitting, and tobacco or vape also create pressure variations or irritations that disrupt healing. Alcohol can increase bleeding and interact with certain medicines, and I advise you to avoid it for at least the first days, while the situation is stable.

When to consult quickly or urgently after extraction

I want to reassure you, the vast majority of suites are simple. But I prefer you to have clear signals, because waiting too long in case of complication often increases discomfort, while early management is easier.

It should also be borne in mind that pain is not the only indicator. Fever, smell, difficulty swallowing, or bleeding that does not yield should be taken seriously.

Warning signs: persistent bleeding, fever, pus, increasing pain, bad smell

Mild bleeding is common, but if it remains abundant despite compression, or if it resumes strongly, you must contact me again or consult. A fever, pus, or pain that increases instead of decreasing, especially after two or three days, are signs that must alert.

A persistent bad smell, with unpleasant taste and deep pain, may evoke alveolite or infection. In this case, it's not in your head, and there are gestures and treatments to relieve and restart healing.

Complications to know: alveolite, infection, numbness (nerf), trismus

L-alveolite often corresponds to loss or alteration of the clot, with pain that can become intense. It usually appears a few days later, and requires treatment at the firm, with cleaning, local dressing if needed, and treatment adaptation.

The infection is manifested by pain, swelling, sometimes discharge, and sometimes fever. Numbness, associated with nerve irritation, is rare but possible, especially if the tooth was close to the inferior alveolar nerve, and this is one of the reasons why imaging and prudence count.

Trismus, which is the difficulty of opening the mouth, is common at first, then regresses. If it gets worse or if it comes with general signs, I prefer to see you again, to check that there is no associated complication.

How much does it cost and how much money do you pay to rip out a wisdom tooth?

The question of cost is legitimate, and I treat it transparently. The budget depends mainly on the complexity of the gesture, the need for complementary imaging, and the type of anaesthesia discussed.

I take the time to explain what is included, what is covered by fees, and what can be covered by Sickness Insurance and your mutual. A clear estimate helps you decide calmly, without surprise.

Factors that make the price vary: simple vs surgery, imaging, anesthesia, number of teeth

A simple extraction does not have the same cost as a tooth surgery included, as operating time and technical gestures differ. Imaging may also vary, between a panoramic view and a CBCT, especially when it is necessary to accurately assess the roots and proximity of the nerve.

The number of teeth removed at the same session also plays, as does the context of anesthesia. In some cases, removing several teeth on the same day simplifies the overall organization, but this can also make the suites more sensitive, and this balance is discussed on a case-by-case basis.

Reimbursement (illness/mutual insurance) and questions to be asked before the act

Before the act, I encourage you to ask for a quote and check your remaining fee, as the reimbursement rules may vary depending on the type of act and your mutual agreement. If fees are exceeded, they must be explained, and you must be able to understand what this covers.

You can also ask me your questions about the schedule, the duration of the shutdown if necessary, and the conditions for resumption of activities. A medical decision is best built when you have a clear vision, and when the relationship remains simple and direct.

If you have any doubts about your wisdom tooth or your symptoms, I recommend you come for an examination and diagnosis tailored to your situation. Depending on the case, you can monitor, treat inflammation, or organize the procedure, with caution and with humans in the centre.
