Keeping asymptomatic wisdom teeth and watching is the choice that most often fails to close the matter: across seven longitudinal studies, about 64% of retained symptom-free third molars are extracted within 18 years, at a steady rate of roughly 3% per year (Bouloux et al., 2015). A same-era 18-year cohort found 73% of the teeth that were unerupted at baseline came out before follow-up ended (Ventä et al., 2004), though that study’s follow-up window overlaps the period Bouloux pooled, so the two are better read as consistent than as independent. The reasons are ordinary: caries, gum disease, later inflammation, and part of that 64% is care that was simply timed to need rather than regretted. The practical upshot is that watching usually defers the operation rather than avoiding it, and the extraction then falls later in life rather than in early adulthood.
Removing the tooth up front does not escape regret either; it relocates it. Because prophylactic removal is itself an extraction, its regret falls on the mirror-image group: the roughly 36% of removed teeth that would have stayed trouble-free over the same 18 years, operated on for nothing. Every one of those extractions carries about a 4.2% chance of a complication, overwhelmingly dry socket, with infection and jaw-joint symptoms far behind (Chen et al., 2021). The Cochrane review found only two studies and 493 people bearing on whether disease-free impacted wisdom teeth should come out at all, and rated the evidence very low certainty (Ghaeminia et al., 2020). NICE went further in 2000, concluding that prophylactic removal of pathology-free impacted third molars should be discontinued in the NHS — a position US practice frequently sets aside.
The two figures are close on purpose, because the decision is close. Both come from the same fact: about two-thirds of these teeth eventually need removal and about a third do not. Watch, and you carry a 64% chance of the surgery you were trying to avoid; remove, and you carry a 36% chance the surgery was needless. Severity runs opposite to frequency — the deferred operation is common but often appropriate, while the unnecessary one is rarer but incurred up front against a benefit the evidence cannot show. What survives the symmetry is a modest lean, consistent with Gilovich and Medvec’s temporal asymmetry: over a long horizon, more people end up back in the chair than are spared it. Whether that reads as regret or as a reasonable bet that mostly postponed a minor operation is the judgement the evidence declines to settle.

[1]Journal of Oral and Maxillofacial Surgery (Bouloux et al. 2015) — What is the risk of future extraction of asymptomatic third molars? A systematic review
Revue par les pairs
Seven longitudinal studies, follow-up 1 to 18 years: cumulative extraction incidence rose from 5% at 1 year to 64% at 18 years — leaving ~36% of retained asymptomatic third molars still not extracted at 18 years
Extrait
“"The mean incidence rate for M3 extraction of previously asymptomatic M3s was 3.0% annually (range 1 to 9%). The cumulative incidence rate for M3 removal ranged from 5% at 1 year to 64% at 18 years. ... The cumulative risk of M3 extraction for young adults with asymptomatic M3s is sufficiently high to warrant its consideration when reviewing the risks and benefits of M3 retention as a management strategy."

The action-side proxy is the mirror image of the inaction figure. If 64% of retained asymptomatic third molars are extracted by 18 years, then roughly 36% are not — those teeth would have stayed trouble-free over that horizon, so removing them prophylactically was, in hindsight, an operation for nothing. We anchor the action proxy at 0.36, the complement of Bouloux's 64% cumulative extraction rate. This is an "unnecessary-surgery" proxy, not a regret survey, and 0.36 is an upper bound: over a full lifetime the never-needed fraction shrinks, because some of that 36% would eventually have required extraction after 18 years. Using the same dataset for both sides keeps the two proxies on one axis.

The policy basis for treating prophylactic removal as regret-prone. A national appraisal body concluded that routinely removing symptom-free impacted third molars should stop, because the benefit is unproven while every extraction carries surgical risk. US practice frequently diverges, which is why this decision is genuinely contested. Establishes the frame; not a rate.

Quantifies what an unnecessary extraction costs. Every prophylactic removal — including the ~36% that were never needed — runs about a 4.2% chance of a complication, dry socket being the commonest and generally self-limiting. Permanent nerve injury is rarer, a few per thousand. Note the population: this cohort is all impacted lower-molar extractions, mixed symptomatic and asymptomatic, not solely prophylactic cases, so the 4.2% is a general operative-risk figure, not a rate specific to the unnecessary subset. Supplies the severity of the action harm, not its frequency.
[4]Cochrane Database of Systematic Reviews (Ghaeminia et al. 2020, CD003879) — Surgical removal versus retention for the management of asymptomatic disease-free impacted wisdom teeth
Revue par les pairs
Two included studies (one RCT with 77 adolescent participants analysed; one prospective cohort of 416 healthy males aged 24–84): only low- to very-low-certainty evidence; insufficient to determine whether asymptomatic disease-free impacted wisdom teeth should be removed or retained
Extrait
“"This review update includes the same two studies that were identified in our previous version of the review ... We found only low- to very-low-certainty evidence of the effects of removal compared with retention ... Insufficient evidence is available to determine whether asymptomatic disease-free impacted wisdom teeth should be removed or retained."

The evidentiary weight behind the action-side regret framing. The benefit a prophylactic extraction is meant to buy — preventing future disease — cannot be demonstrated: the whole randomised-plus-cohort evidence base is two studies and 493 participants, rated low to very low certainty. This is why removing a symptom-free tooth is treated as regret-prone rather than clearly protective. Establishes the strength of the evidence, not a rate.

The inaction-side proxy. Retained asymptomatic third molars are extracted at about 3% per year, so the cumulative share removed climbs to 64% by 18 years. We anchor the inaction proxy at 0.64, taken directly from this figure. The regret construct: watching does not usually spare the surgery, it defers it, and the extraction then happens later in life. (Conventional oral-surgery teaching holds that later extraction in an older patient is harder, though Chen 2021 — cited below — found no age association with complications in its own cohort, so we do not lean on that claim.) This is a "needed extraction anyway" rate, not a survey asking whether people regret having waited, and part of that 64% is appropriately-timed care rather than a mistake.

A same-order-of-magnitude 18-year cohort: 118 adults tracked from a mean age of 20 to 39, most third molars unerupted at baseline ending up removed (roughly two-thirds to three-quarters over ~18 years). Treat this as consistency, not clean independent replication: Bouloux 2015 is a systematic review whose only 18-year datapoint plausibly draws on this same cohort, so we cannot confirm this is a wholly separate measurement of the 64%. Small sample; supports the direction of the inaction proxy, not an independent rate.
Réserves
Les deux chiffres sont des proxys tirés du même fait sous-jacent — qu'environ 64 % des troisièmes molaires asymptomatiques conservées sont extraites sous 18 ans (Bouloux 2015 ; cohérent avec la cohorte de Ventä 2004, dont la fenêtre de 18 ans peut chevaucher les études regroupées par Bouloux) — de sorte qu'ils se situent sur un même axe, mais aucun n'est une enquête de regret. Les 64 % de l'inaction sont un taux de "vous avez eu besoin de la chirurgie au bout du compte" ; les 36 % de l'action en sont le complément, la part des dents extraites préventivement qui seraient restées tranquilles sur le même horizon, une opération faite pour rien. La comparaison est délibérément serrée parce que le choix est serré : l'extraction préventive est elle-même une extraction à 100 %, donc surveiller ne fait jamais pire sur l'axe "éviter la chirurgie" — cela donne ~36 % de chances de ne jamais avoir besoin de l'opération et ~64 % de chances de l'opération que l'on aurait eue de toute façon, simplement plus tard. C'est pourquoi le delta est modeste plutôt que déséquilibré, et pourquoi aucun côté ne l'emporte nettement. La gravité court à l'inverse de la fréquence : le dommage de l'action est encouru d'emblée, sur une bouche plus jeune et plus facile à opérer, contre un bénéfice que la revue Cochrane (Ghaeminia 2020 — seulement 493 participants dans deux études, certitude très faible) ne peut pas démontrer ; le dommage de l'inaction est plus fréquent mais n'est souvent qu'un report, et une partie de ces 64 % est un soin simplement calé sur le besoin, après qu'une dent est réellement devenue malade, pas une erreur regrettée. Le chiffre d'action de 36 % est une borne supérieure pour deux raisons. D'abord, sur une vie entière, davantage de dents conservées finissent par nécessiter une extraction, ce qui réduit la part de celles qui n'en auraient jamais eu besoin. Ensuite, il emprunte le taux de la cohorte de rétention, mais les dents effectivement choisies pour une extraction préventive ne sont pas un tirage aléatoire — les cliniciens tendent à retirer l'anatomie la plus à risque (inclusion profonde, angulation mésio-angulaire, contact étroit avec la deuxième molaire), qui est plus susceptible de poser problème plus tard. La part des "jamais nécessaires" parmi les dents réellement retirées est donc probablement inférieure à 36 %, et ce biais de sélection vers le traitement joue contre le côté action. Les 4,2 % de complications de Chen proviennent de toutes les extractions de molaires inférieures incluses, cas symptomatiques et asymptomatiques mêlés, pas seulement des cas préventifs. C'est une décision authentiquement disputée — le NICE a conclu en 2000 que l'extraction préventive des troisièmes molaires incluses sans pathologie devait être abandonnée dans le NHS, tandis que la pratique américaine les retire fréquemment. Les populations sont taïwanaise, finlandaise et internationales regroupées, pas américaines. La direction de prédominance de l'inaction est cohérente avec le cadre d'asymétrie temporelle de Gilovich et Medvec, mais elle est ici étroite et dépend du poids que l'on donne à un report fréquent face à une opération inutile d'emblée, plus rare.
