Aim To assess obesity as a risk factor for tooth loss over 5 years in an urban sample of Brazilian adults. Materials and methods A total of 1586 individuals were surveyed using a multistage probabilistic approach. Five years later, 635 individuals 14‐64 years old were re‐examined. An incident case of tooth loss was determined for a participant that had lost at least one tooth over time. Obesity was evaluated by calculating body mass index at baseline and by the change in obesity status over time. Results Incident cases of tooth loss were significantly more frequent among obese (47.1%) than normal‐weight individuals (32.4%) ( p = .004). Obese individuals had 31% higher risk [relative risk (RR) =1.31; 95% confidence interval (95%CI) 1.04‐1.65] for tooth loss than normal‐weight individuals adjusting for age, socio‐economic status, smoking, dental care and periodontitis. This association was significant for females (RR=1.47, 95%CI 1.08‐2.01), but not for males. The risk for tooth loss was also modified by presence of periodontitis at baseline and lifetime smoking exposure. There was an increased risk for tooth loss for those that remained obese than those that remained normal weight. Conclusion Obesity is associated with higher risk for tooth loss. This association was modified by sex, periodontal status and smoking.
