Objectives To investigate the influence of oral health conditions, socioeconomic status and dental care utilization on subjective happiness and identify the factors associated with changes in happiness among adolescents. Methods Data were collected in 2012 and 2014. Oral health conditions were evaluated by performing clinical examinations; socioeconomic status and dental care utilization were assessed by using a questionnaire. The participants answered the Child Perceptions Questionnaire 11‐14 for the evaluation of the impact of these variables on oral health‐related quality of life (OHRQoL). Happiness was assessed using the Brazilian version of the Subjective Happiness Scale. For longitudinal data analysis, a mixed‐effect model of linear regression was used to assess the factors related to happiness and multinomial logistic regression to appraise prospective changes in happiness. Results A total of 1134 12‐year‐old adolescents were examined at baseline (response rate: 93%), and 770 were reevaluated after 2 years (retention rate: 68%). The adolescents who lived in households with lower equivalized income and greater overcrowding, had not visited the dentist in the later 6 months, had a higher number of cavitated carious lesions, and reported a higher impact on OHRQoL in 2012 presented lower happiness levels. Additionally, the adolescents with a higher number of decayed, missing or filled teeth and who reported a higher impact on OHRQoL were more likely to belong to the most unfavourable happiness trajectory categories. Conclusions The presence of dental caries, socioeconomic conditions, dental care utilization and OHRQoL influence happiness in adolescents. Having more teeth affected by dental caries and worse self‐perception in early adolescence can lead to a decrease in happiness.
