Background: Tooth loss is known to have negative effects on both functional and psychological oral health-related quality of life (OHRQoL), but the impact of the position of the tooth loss (i.e. anterior or posterior) on the different psychosocial dimensions of OHRQoL has yet to be examined. Here, we examined how the position of lost teeth impacts the different dimensions of OHRQoL. Methods: This was a cross-sectional epidemiological study of adults aged 18 years and older attending routine examinations at primary care dental centers in Jeddah, Kingdom of Saudi Arabia. Demographic information was collected, and OHRQoL was assessed using the Oral Health Impact Profile-14 (OHIP-14) (Arabic form). Differences in total and subdomain OHIP-14 scores between individuals without tooth loss and those with ≥1 anterior or posterior missing teeth were assessed using Student's t-test, and analysis of covariance was used to assess the association between the presence and absence of missing teeth in each compartment and total and subdomain OHIP-14 scores after controlling for age, gender, and income. Results: The overall prevalence of tooth loss was 76%. In multivariate analysis controlling for age, gender, and income as covariates, anterior missing teeth were significantly associated with higher OHIP-14 total, physical pain, physical disability, psychological disability, and social disability scores, accounting for 6%–12% of the score variance. However, posterior missing teeth were only associated with total OHIP-14 and functional limitations domain scores, accounting for 6% and 7% of the variance, respectively. Conclusions: Here, we show for the first time the impact of the location of missing teeth on different OHRQoL dimensions. Anterior tooth loss has a wide-ranging impact on both physical and psychosocial functioning compared to posterior tooth loss, suggesting that anterior tooth restoration should be prioritized when treatment planning. The position of lost teeth must be considered in addition to the number of losses when examining the impact of tooth loss and its treatment on OHRQoL.
