Objective: To investigate the major causes of tooth loss among patients attending Riyadh Elm University (REU) hospital, taking into consideration the patient's age, gender, and tooth type.

Subjects and Methods: Data were collected by undergraduate, postgraduate students, and interns through a questionnaire with specific inclusion and exclusion criteria. The specification of the patient's age, gender, tooth type, and the reason for extraction was required.

Results: A total of 895 teeth were extracted from 385 patients, of which 51% were extracted due to dental caries, whereas 21% were extracted because of periodontal disease. There is a statistically significant relationship between age and reasons for tooth extraction (P-value < 0.000). Maxillary molars were extracted mostly due to dental caries (64.8%). On the contrary, mandibular anterior teeth were extracted mainly due to periodontal disease (39.6%). No significant relationship was detected between gender and reasons for tooth extraction.

Conclusion: Dental caries and periodontal disease were the leading causes of tooth extraction.
