Introduction: Odontogenic infection is polymicrobial, consisting of various facultative and strict anaerobes. The dominant isolates are strictly anaerobic gram-negative rods and gram-positive cocci. Aims and Objectives: To identify the most common microorganisms responsible for causing infection and different species in oral infections. To evaluate the common types of dental infections and its site. To identify the sensitivity and resistance of antibiotics. Materials and Method: This study was conducted on 62 subjects, of which 11 showed no pathogens. After collection of the sample, it was sent to the microbiology laboratory for aerobic and anaerobic culture, gram staining, and antibiotic susceptibility test. Results: Staphylococcus (40.3%, n = 25) was the most commonly found microorganism. Maxillary anterior (32.25%, n = 20), maxillary posteriors (32.25%, n = 20), and mandibular posteriors teeth (27.4%, n = 17) showed almost similar occurrences. Maximum resistance was shown to co-trimoxazole (70.5%), amoxicillin (62.7%), erythromycin (54.9%), and azithromycin (37.25%). Linezolid (78.4%), amoxiclav and gentamicin (39.2%), vancomycin, imipenem, doxycycline showed (56.9%), and cefuroxime showed 37.25% sensitivity. Conclusions: Appropriate and correct use of antibiotics is essential to ensure that effective and safe treatment is available. The result of the present study should not be considered an absolute one; however, they can serve to increase awareness about the pathogens responsible for different infections and the sensitivity and resistance toward different antibiotics.
