Objective: To investigate why women avoid dental visits during pregnancy and to explore the possible association between this attitude and relevant socio-demographic factors. Material and Methods: An online questionnaire was distributed to pregnant women during their routine visits to antenatal clinics in Al Madinah, Saudi Arabia. The questionnaire explored socio-demographic factors of age, education, employment status and nationality. It also explored misconceptions/ reasons for avoiding dental visits during pregnancy. Results: A total of 360 pregnant women participated, and their mean age was 30.08 years (range=18-52 years, SD=5.96). The most commonly cited misconception/reason for avoiding dental visits was "local anesthesia is not safe during pregnancy", followed by "transportation is difficult" and lastly, "dental treatment is not safe during pregnancy", (43.6%, 37.5%, 18.9%, respectively). Illiterate participants were statistically significantly associated with the misconception of "unsafe dental treatment during pregnancy" (p=0.002), whereas school-level and unemployed participants were statistically significantly associated with the misconception of "unsafe local anesthesia during pregnancy" (p=0.02, p=0.036 respectively). Conclusion: Pregnant women avoid dental visits mainly due to the misconception that local anesthesia is not safe during pregnancy. Difficult transportation seems to be another important deterrent in preventing pregnant women to visit dentists in this geographic area. Changing the misconceptions should be the starting point in addressing this public health problem and this should involve the three parties involved: pregnant women, oral healthcare providers and obstetric care providers.
