Background and objective This study aims to explore the concept of preemptive analgesia, which is the technique of administration of analgesic agents before the painful stimulus. This bridges the time gap between the onset of action of the analgesic agents and the wear-off of local anesthesia. Existing literature also brings up the concept of central sensitization, which is the hyper-activity of the nervous system in response to a noxious stimulus. Administration of preemptive analgesia prevents central sensitization and hence provides prolonged analgesia to the patient. For the benefit of this study, tab. Etoricoxib 90 mg was used as the analgesic agent. In addition, this study aims to investigate the effects of the administration of tab. Etoricoxib 90 mg 30 minutes before extraction of a single mandibular third molar on the effects of pain experienced by the patient after tooth extraction as compared to a placebo. Methodology This was a double-blinded, prospective, observational study. The pain experienced by 50 participants in each group was measured at 1 hour, 6 hours, 12 hours, and 24 hours postoperatively using a visual analog scale (VAS). The independent samples t-test was then conducted to evaluate the results and draw out conclusions. Results The average difference in pain experienced was maximum in the first hour after the procedure. The mean VAS score reported by patients was 3.14 in the study group but was 6.40 in the control group within the first hour. This difference was reduced in the first six hours after the procedure, with the average score being 3.82 in the study and 7.16 in the control group. The difference was the least after 12 hours, with the study group experiencing a VAS score of 4.64 and controls experiencing a VAS score of 6.14. After the first 24 hours, the mean VAS score was 3.80 in the study group and 5.60 in the control group. Conclusions Preemptive administration of tab. Etoricoxib 90 mg can reduce postextraction pain in healthy adult patients as compared to placebo tablets, with a maximum difference in pain reduction seen at the end of the first six hours (P = 0.012) and the minimum at the end of 12 hours (P = 0.0197).
