BackgroundTo provide effective oral health care to patients and healthy individuals, it is critical to recognize prevalent myths. Most myths cause patients to follow the wrong protocol in dentistry, which can make treatment difficult for the dentist. This study aimed to assess dental myths among the Saudi Arabian population in Riyadh. MethodologyA descriptive cross-sectional questionnaire survey was conducted among Riyadh adults between August and October 2021. Saudi nationals aged 18-65 living in Riyadh without cognitive, hearing, or vision impairments and with limited or no trouble interpreting the questionnaire were surveyed. Only participants who consented to participate in the study were included. JMP Pro 15.2.0 was used to evaluate survey data. Frequency and percentage distributions were used for dependent and independent variables. The chi-square test evaluated the statistical significance of the variables, with a p-value of 0.05 being considered statistically significant. ResultsA total of 433 participants completed the survey. Half of the sample (50%) were aged 18-28; 50% were men; and 75% had a college degree. Higher-educated men and women did better on the survey. In particular, 80% of the participants believed "teething causes fever." "Placing a (pain killer) tablet on a tooth reduces pain" was believed by 34.40% of the participants, and 26% thought pregnant women should not get dental work. Lastly, 79% of the participants believed that "infants obtain calcium from their mother's teeth and bone." Most sources of these pieces of information were online (62.60%). ConclusionsNearly half of the participants believe in dental health myths, and as a result, people follow unhealthy practices. This results in long-term health consequences. The government and health professionals must prevent the spread of such misconceptions. In this regard, dental health education may be helpful. Most of this study's crucial findings are consistent with those of prior studies, indicating its accuracy.
