The short answer
No — there is no rule that wisdom teeth (Weisheitszähne) come out as a set of four. Each of the four is assessed on its own: its position, whether there is room for it, whether you can keep it clean, and whether there is an actual finding on it or on the tooth in front. German dental associations take the view that symptom-free, healthy wisdom teeth in a sound position do not have to be removed simply because they are wisdom teeth. In practice, three outcomes are all common: all four out, one or two out, or none out with regular monitoring. Not everyone even has four to begin with — it is common for one or more wisdom teeth never to develop at all. The question to ask your dentist is not “should they come out?” but “what is the finding on each one?”

Where the "all four at once" idea comes from
It has an understandable history. For decades, in many countries, removing all four in the late teens was close to routine — the reasoning being that they would cause trouble sooner or later, that healing is easier at that age, and that one operation beats three appointments spread over years.
Convenience is a real argument and it has not disappeared. What has changed is the starting assumption. The position reflected in the guidance used in Germany is that removal needs a reason for that particular tooth, and a healthy, fully erupted, cleanable wisdom tooth causing nothing is not automatically a problem waiting to happen. Imaging is the other thing that changed: a panoramic X-ray (OPG), and where justified a 3D X-ray (DVT), shows each tooth’s position and its relationship to the nerve canal below or the sinus above — so the assessment can be specific rather than general.
What is actually assessed on each tooth
Six questions, applied separately to each of the four positions.
Is it through, and is it upright? A wisdom tooth that has erupted fully, stands straight, and meets an opposing tooth is functionally an ordinary molar. A tooth lying at an angle, partly covered by gum, or completely buried in bone is a different proposition — not automatically a problem, but a different one.
Is there room? The jaw either has space behind the second molar or it does not. Where there is not, a tooth pushing forwards can press against its neighbour, and that pressure occasionally damages the root of the tooth in front — a finding that carries weight, because that neighbour is a tooth you very much want to keep.
Can it be cleaned? This is the practical criterion that decides many cases. A partly erupted lower wisdom tooth with a flap of gum over part of it creates a pocket that no toothbrush reaches. That pocket is where recurring inflammation of the gum flap comes from, and repeated episodes are one of the clearest reasons to remove a tooth.
Is there a finding on it — or caused by it? Decay on the wisdom tooth or on the back surface of the second molar, a deep gum pocket, root resorption of the neighbour, or a cyst forming around the crown of a buried tooth. Findings decide; predictions do not.
What is the tooth opposite doing? This is where the “in pairs” logic genuinely applies. If a lower wisdom tooth is removed and the upper one has nothing to bite against, it can gradually drift downwards over years, which eventually causes its own problems. So removing a lower tooth sometimes makes a case for removing the upper one on the same side — not because four is the number, but because those two are a functional pair.
What else is planned? Orthodontic treatment, a denture, or implant work in the area can change the assessment, since the wisdom tooth’s position affects planning. Occasionally the opposite applies and a wisdom tooth is worth keeping precisely because it may serve as an anchor later.
Keep or remove: the honest comparison
| Speaks for keeping | Speaks for removing |
|---|---|
| Fully erupted, upright, meets an opposing tooth | Tilted or lying against the second molar |
| You can clean it properly and it is free of decay | Partly covered by gum, with a pocket that cannot be cleaned |
| No symptoms, no findings on X-ray | Repeated inflammation of the gum flap |
| Bone and gum around it are healthy | Decay on the wisdom tooth or on the neighbour’s back surface |
| It could be useful for future prosthetic planning | A cyst has formed around the crown of a buried tooth |
| Removal would carry particular risk in your case | The root of the tooth in front is being resorbed |
| — | Deep gum pocket behind the second molar that will not settle |
Two entries in that table deserve emphasis, because they are what turns a wait-and-see tooth into a remove-it tooth: damage to the neighbour, and a pocket that cannot be cleaned. Both are about the tooth in front, which is worth more to you than the wisdom tooth is.
When wisdom teeth may simply stay
It is worth stating this positively, because patients are often surprised to hear it.
A wisdom tooth may stay where it is fully erupted and functional, or where it is completely buried in bone with intact bone all around it, no contact with the mouth, and no finding. A tooth that is entirely enclosed has no route for bacteria to reach it. Removing it would mean opening healthy bone for no current gain.
Staying is not the same as being ignored, though. A tooth that stays is a tooth that gets looked at — clinically at check-ups, and on an X-ray at sensible intervals, since findings around buried teeth develop without symptoms. That is monitoring, not neglect, and it is a legitimate plan.
The reverse case also exists: circumstances where removal is normally advised even without symptoms — for instance where a cyst has formed around the crown, or where the neighbouring tooth is being damaged. The detailed list of indications belongs to a separate article: When do wisdom teeth have to come out — and when can they stay?.
One appointment or several?
If two or more do need removing, the next question is how to arrange it. There is no single right answer, and this is a genuine choice you should be offered rather than told.
One side at a time (upper and lower together). The most common arrangement. You keep one side of your mouth fully usable for eating, which makes the first few days considerably easier. It means two appointments and two recovery periods.
All at once. One operation, one recovery, one period off work — attractive if you are organising around a job or a course, and the usual choice where sedation is involved. The trade-off is that both sides are sore at the same time and eating is more restricted for a few days.
Only the tooth that has the finding. Where one tooth is clearly a problem and the others are not, doing only that one is entirely reasonable, and revisiting the others later is not a failure of planning.
Practical factors reasonably influence this: how far you travel, whether anyone can collect you afterwards, exams, deadlines, childcare, and whether you would rather have one difficult week than two mildly awkward ones. Say what suits your life — it is legitimate input, not an inconvenience.
Upper and lower are not the same operation
Patients who have had one wisdom tooth out sometimes assume the next will feel identical. Often it does not.
Upper wisdom teeth generally sit in less dense bone, are frequently more straightforward to remove, and recovery is often quicker. The structure of interest above them is the maxillary sinus, whose floor can lie close to the roots.
Lower wisdom teeth sit in denser bone, are more often tilted or buried, and more often require the gum to be opened and some bone removed, or the tooth to be divided so it can be taken out in pieces. Dividing a tooth sounds alarming and is entirely routine — it usually means less bone has to be removed, not more. The structure of interest here is the nerve canal supplying feeling to the lip and chin, which is what 3D imaging assesses when roots appear close to it on a flat X-ray.
So a plan that says “upper left straightforward, lower left more involved” is not a warning. It is the level of detail you want before agreeing to anything.
Anaesthetic, sedation and anxiety
Wisdom tooth removal is normally carried out under local anaesthetic (Betäubung). You are awake, you feel pressure, movement and vibration, but not sharp pain. Sharp pain during the procedure is not something to endure silently — say so, and more anaesthetic is given.
For patients who find dental treatment genuinely difficult, sedation and laughing gas (Lachgas) are available in our practice. Bring it up at the consultation rather than on the morning of surgery, because it affects planning, how you get home, and often how the appointments are arranged. Being anxious about this is common and is not something you need to apologise for or talk yourself out of.
What the operation itself feels like is covered in more depth here: Does wisdom tooth surgery hurt?.
What's normal afterwards — and when to contact us
This is the part to save. After wisdom tooth removal there is a wide band of entirely normal experiences, and a short list that means picking up the phone.
Our opening hours are Monday to Friday 07:30–19:30 and Saturday 08:00–18:00, so a Saturday morning question can be dealt with the same day rather than waiting for Monday. Outside those hours the dental out-of-hours service (zahnärztlicher Notdienst) in your region of NRW covers evenings, Sundays and public holidays — this is the number to use for a night-time bleed that will not stop, and it exists for exactly that.
Cost and coverage, in brief
Removal of a wisdom tooth for a medical reason is, as a rule, covered for patients with statutory health insurance (gesetzliche Krankenversicherung, GKV) — it is treatment of a finding, not an elective extra. What can fall outside that are additional services: certain imaging, and sedation or general anaesthesia chosen for comfort rather than required by a specific medical situation. Anything payable by you is set out in writing beforehand, and the amount depends on the individual finding, so general figures are not worth quoting. The two articles that go into this properly are Does statutory insurance cover wisdom tooth removal? and What does wisdom tooth removal cost?.
If you are new to Germany
Three things routinely catch international patients out with this particular procedure.
If sedation is planned, you will usually be asked to bring someone with you. Arrange that in advance; it is not a formality that can be waived on the day.
Sick notes are normal and expected. A certificate of incapacity for work (Arbeitsunfähigkeitsbescheinigung) after wisdom tooth surgery is routine — ask for it at the appointment rather than afterwards. Bring your health insurance card (Gesundheitskarte / eGK), and any panoramic X-ray you already have from another practice, which saves repeating an image.
Take the consent conversation seriously. You will be told about the specific considerations for your teeth — the nerve in the lower jaw, the sinus above the upper ones — and you should understand that conversation, not merely sit through it. With us it can happen in English: English-Speaking Dentist in NRW. From Düsseldorf, Cologne or Bonn, Wuppertal is a 20 to 30 minute journey — an ordinary distance for surgery you want explained in a language you think in. We also work in German, Russian, Turkish, Ukrainian, Arabic, Kurdish and French.
Neither is medically superior in most cases; it is a trade-off. All at once means one recovery and one period off work, but both sides are sore simultaneously. One side at a time leaves you a functioning side to chew on. Where sedation is used, doing more in a single session is often the practical choice.
Not for that reason alone. Absence of symptoms is one factor among several — position, cleanability, the state of the neighbouring tooth and the X-ray findings all count too. Some situations justify removal without symptoms, such as a cyst around the crown or damage to the tooth in front, but “they might cause trouble one day” is not on its own a sufficient reason under current German guidance.
No, but age does affect the picture. Bone becomes denser and roots are fully formed, so surgery can be more involved and healing a little slower than at twenty. Wisdom teeth are removed at all adult ages when there is a reason to; the assessment simply weighs the benefit against a slightly greater undertaking.
This is often assumed and is not well supported. Front teeth tend to crowd with age in people who never had wisdom teeth at all, so wisdom teeth are unlikely to be the main cause. They are, however, sometimes removed as part of orthodontic planning for reasons specific to the treatment.
Plan for two quiet days, with most people back to normal activity within a few days to a week depending on how involved the surgery was. Swelling peaks around day two or three, so scheduling surgery immediately before an important presentation is a decision people regret. Ask for a sick note at the appointment.
Four wisdom teeth are four separate decisions that happen to sit in the same mouth. Some come out because of a finding, some come out because of the tooth opposite, and some can stay under observation for years without ever becoming a problem.
The useful conversation is a specific one: what does the X-ray show for each of the four, what is the reason for removing this particular tooth, and what happens if it stays. If you get answers at that level of detail, the decision usually makes itself — and it may well not involve the number four.
