Introduction Antibiotic prophylaxis for tooth extractions is a common practice in dentistry to prevent postoperative infections. However, the routine use of antibiotics has been questioned due to concerns about bacterial resistance and potential side effects. This study aimed to evaluate the necessity of postoperative antibiotics in patients undergoing orthodontic tooth extraction. Materials and methods This prospective study involved 100 patients requiring orthodontic tooth extraction, divided into two groups. The patients were recruited from Saveetha Dental College and Hospital, Chennai, India, after obtaining approval from the Institutional Human Ethics Committee, Saveetha Dental College (approval number: IHEC/SDC/OMFS-2103/23/293). Group 1 (n = 50) received antibiotics (amoxicillin 500 mg, three times a day for three days) after extraction, while Group 2 (n = 50) did not receive antibiotics. Postoperative infection was assessed on postoperative days (POD) 3 and 7. Data analysis was conducted using IBM SPSS Statistics for Windows, version 26.0 (released 2019, IBM Corp., Armonk, NY). Categorical variables were presented as frequencies and percentages, and differences between groups were assessed using chi-square or Fisher's exact tests. A p-value of <0.05 was considered statistically significant. Results The incidence of postoperative infection was recorded in both groups. In group 1 at POD 3 and POD 7, there were two patients and one patient with infection, respectively. In group 2 at POD 3 and POD 7, there were four patients and two patients with infection, respectively. Conclusion The findings of this study suggest that the routine administration of antibiotics for the non-traumatic extraction of teeth in healthy patients might not be necessary. The absence of postoperative infections in patients who did not receive antibiotics indicates that antibiotics may be avoidable in many cases of orthodontic tooth extraction. These results emphasize the importance of reconsidering the widespread use of antibiotics to combat the growing concern of bacterial resistance. Antibiotics should be prescribed judiciously, only for patients with specific medical conditions who are prone to infection. One of the limitations of this study is the limited sample size; hence, studies with larger and heterogeneous groups should be done to validate the same.
