Q1. Does an extraction actually count as “surgery”?

In the classification used by the literature, tooth extraction is a surgical procedure: Cochrane compares techniques directly under the title of surgical removal of mandibular wisdom teeth and sets out the indications and the complications [F11][F12]; and the SECIB guideline describes third molar extraction as the most frequently performed surgical procedure in the field of oral surgery [F1]. That is also why the literature, when it discusses this, lists the indications and the complications together [F11][F12]; and where the evidence is insufficient, what Cochrane offers is shared decision-making that takes in patient values, with clinical assessment at regular intervals if the decision is to retain [F6].

Q2. My wisdom tooth is not uncomfortable — does it still need to come out?

This question currently has no high-certainty evidence-based answer. The authors' conclusion in the Cochrane systematic review is that, for the class of impacted wisdom teeth that are neither symptomatic nor associated with disease, the available evidence is insufficient to determine whether they should be removed or retained [F3]; what the literature therefore offers is shared decision-making that takes in patient values, with clinical assessment at regular intervals if the decision is to retain [F6]. The judgement about your own particular tooth falls within the scope of supplementary canonical card S01 (in production) and is not answered here [F32].

Q3. Do antibiotics always have to be taken for an extraction?

Not by default. The Cochrane result does show that prophylactic antibiotics may reduce postsurgical infectious complications by approximately 66% and reduce the risk of dry socket by 34%, but the same review also gives the corresponding numbers needed to treat — about 19 people need to take antibiotics to prevent one infection, and about 46 people to prevent one case of dry socket; both are low-certainty evidence, and the population included was mostly healthy people undergoing surgery for impacted third molars [F24][F25]. A 2025 review of reviews requires that their administration be carefully considered to balance benefits against potential risks [F26], while another systematic review cited in this article reaches the opposite conclusion, that antibiotic prescription does not avoid postoperative complications after lower third molar surgery [F37]. Whether they are prescribed is assessed patient by patient by a dentist [F25]; this article gives no medication advice [F31].
