Extraction dent de sagesse : ce que vous devez savoir
Une dent de sagesse qui pose problème ne s'arrange pas avec le temps
L'extraction des dents de sagesse est un geste courant, mais rarement vécu comme anodin. Elle est souvent recommandée pour éviter des douleurs, des infections ou une pression sur les dents voisines. À Paris, le Dr Solène Vo Quang évalue l'indication au cas par cas, vous explique le déroulé de l'intervention et vous accompagne jusqu'à la cicatrisation complète.
Quand une dent de sagesse cesse d'être discrète
Les dents de sagesse arrivent tard, entre 17 et 25 ans, sur une mâchoire qui a déjà trouvé son équilibre. Quand la place manque, elles forcent, s'inclinent, ou restent bloquées sous la gencive. Les signes reviennent alors par épisodes, avec des périodes d'accalmie qui rassurent à tort.
La douleur qui revient
Une gêne au fond de la bouche qui s'apaise, puis réapparaît un peu plus forte. C'est le signe que la situation évolue, pas qu'elle se règle.
La gencive qui s'enflamme
Rouge, gonflée, douloureuse au brossage : c'est souvent une péricoronarite, l'infection de la gencive qui recouvre une dent en cours d'éruption.
La dent voisine menacée
Entre la dent de sagesse et la deuxième molaire, la plaque s'accumule là où aucune brosse n'arrive. C'est la dent 7 qui se carie, et c'est elle qu'il faut protéger.
Le kyste silencieux
Certaines dents incluses ne font jamais mal et ne se signalent que sur une radiographie. C'est pour cette raison qu'un bilan vaut mieux qu'une attente.
Why have a wisdom tooth removed?
Common problems caused by wisdom teeth
Wisdom teeth come through late, usually between 17 and 25, at a point where the jaw has already found its balance.
When there isn't enough room, they push, tilt, become inflamed, or stay trapped under the gum.
I regularly see patients who alternate between painful episodes and quiet spells, until the day the infection comes back stronger than the last one.
The most common situations:
- a painful or inflamed gum (pericoronitis),
- decay forming on the neighboring tooth,
- a diffuse pain radiating towards the jaw or the ear,
- or sometimes a cyst developing silently.
When these signs keep coming back, removal is no longer an option: it's the safest way to protect your oral health long term.
The case for removing them early
Acting early, even before the pain sets in, brings several benefits: faster healing, roots that are less developed, a simpler surgical procedure and a more comfortable recovery.
I often tell my patients: taking a wisdom tooth out at the right time means avoiding a heavier procedure later.
When should a wisdom tooth be removed?
The usual age for this procedure
The ideal window is between 18 and 25.
At that age the bone is more flexible and the roots are still short, which makes for a precise procedure and less discomfort afterward.
Later on it remains perfectly possible, but it sometimes calls for extra precautions.
Symptoms that point to removal
Some signs are unmistakable: pain when chewing, pressure in the jaw, a gum that flares up regularly, persistent bad breath, an unpleasant taste, or the feeling that the tooth is pushing against the others.
Even with no pain at all, an X-ray can reveal a fully impacted tooth, likely to cause complications later.
My job is to help you decide with every piece of information in hand.
What happens during wisdom teeth removal
Pre-operative consultation and imaging
Before any extraction, I run a full assessment: a panoramic X-ray, a 3D CT scan if needed, and a conversation where you describe your symptoms, your worries, your history.
That moment matters.
It lets me analyze the exact position of the tooth, how close it sits to the nerve, the shape of the roots, and it also lets me adapt the procedure to how comfortable you feel.
The steps of the surgical procedure
The procedure usually takes 20 to 45 minutes, depending on how many teeth are involved and how complex they are.
Under local or general anesthesia, I reach the tooth gently and release it progressively, sometimes sectioning it into fragments to avoid pulling on it.
Once the tooth is out, the site is cleaned carefully, then stitched.
With today's techniques, pain during the procedure itself is fully controlled.
Which type of anesthesia is used?
Local or general: how to choose
The choice depends on how many teeth need removing, where they sit, and how anxious you feel.
- Local anesthesia is enough for one or two teeth.
- General anesthesia is sometimes preferable to take all four out in a single session.
I always walk you through both options, and I never impose one.
Contraindications and precautions
Before the procedure, we go through your medications, allergies, medical history and any contraindications.
That conversation is what keeps you safe, and it lets me adapt the procedure openly.
Recovery after wisdom teeth removal
How long healing takes
Most of the discomfort lasts 2 to 3 days, with swelling peaking on day 2.
Most patients feel comfortable again in under a week, even though complete healing takes 10 to 15 days.
Eating and oral hygiene after surgery
The first 48 hours call for gentleness: cold or lukewarm food, soft textures, no pressure on the operated site.
Brush as you normally would, but leave the area alone for the first few days.
Salt water rinses start after 24 hours, never before.
And ice for 10 minutes, several times a day, remains one of the simplest and most effective things you can do.
Possible complications and how to prevent them
Pain, swelling, infection: what to watch for
Light bleeding on the first day is normal, and so is a swollen cheek.
What should alert you:
- pain that increases instead of easing,
- a fever,
- a persistent unusual taste, which can point to a dry socket,
- or continuous bleeding.
In those situations, I would rather see you quickly.
When to come back after the procedure
A check-up is scheduled around day 7 to review the healing, remove the stitches if needed, and make sure everything is progressing normally.
In the meantime I stay available if a doubt comes up, and no question is ever too small.
Getting back to normal after an extraction
How soon you can go back to work or study
You can usually go back within 2 to 3 days after a straightforward extraction.
For all four teeth, 4 to 5 days of rest is often preferable, to avoid unnecessary fatigue or pain.
Sport and physical activity: what I recommend
Intense exercise is best avoided for a week.
A rise in blood pressure or an impact could trigger pain or late bleeding.
Build back up gradually, and listen to your body.
Fees and cover in 2025-2026
Average cost of wisdom teeth removal
The fee depends on complexity: between 100€ and 400€ per tooth.
I always explain the exact cost before the procedure.
Cover by the French health service
If the procedure is medically justified, the French health service (Sécurité sociale) covers 70% of the base rate.
Any additional fees are explained upfront, openly.
Ce qu'il faut retenir
Quatre repères, du premier symptôme à la cicatrisation
Reconnaître le moment
Une douleur qui revient, une gencive qui s'enflamme, un goût désagréable persistant : ces signes justifient un avis, pas une attente.
Poser le diagnostic
Radiographie panoramique, scanner si nécessaire : la position de la dent, la forme de ses racines et sa proximité avec le nerf décident de la suite.
Choisir le bon moment
Entre 18 et 25 ans, l'os est plus souple et les racines encore courtes. Intervenir tôt, c'est un geste plus simple et des suites plus légères.
Récupérer sereinement
Deux à trois jours de gêne, un gonflement maximal à J+2, un contrôle à J+7. Le froid et une alimentation douce font le reste.

Wisdom teeth removal: your questions
Answers to what patients ask me most
Sometimes yes, sometimes no. Let me be straight with you: a wisdom tooth that doesn't have enough room won't settle back into place on its own. But in some patients, early orthodontic follow-up or regular monitoring is enough to avoid an extraction. It all comes down to the position, the space available and your history of inflammation, which is exactly why a precise assessment matters.
It can be.
Repeated pain, an infection or swelling are all signs that the situation is moving.
The longer you wait, the more the inflammation settles in, and the more uncomfortable the procedure becomes.
I say it often: acting before the crisis makes for a far calmer recovery.
A badly positioned tooth can put pressure on the neighboring teeth.
The extraction itself doesn't twist your teeth; on the contrary, it removes a force that was already disturbing the alignment.
If you're wearing orthodontic treatment, the procedure can even protect the result you've achieved.
There's no rule.
We take out what's causing trouble, nothing more.
That said, when a CT scan shows that all four are going to cause complications, removing them in one session (under general anesthesia) means a single recovery, simpler and faster.
