Background: Dental veneers have gained growing interest recently as an aesthetic dental treatment. However, the public’s understanding of veneers’ benefits and risks is unclear. Aim: To assess the awareness and knowledge of the public about dental veneers in Saudi Arabia. Methods: This cross-sectional study employed an Arabic questionnaire, which consisted of three sections: demographic information, awareness about oral hygiene, and awareness about dental veneers. Correct responses to knowledge questions were assigned one point, and all points were summed to calculate the total knowledge score. Results: The study included 340 eligible respondents, out of whom 51 (15%) used veneers. Most responses to knowledge questions were correct. However, more than half of the participants wrongly thought that dental veneers are indicated for the correction of severely crowded teeth or to replace missing teeth, and 40.3% did not know that they require the removal of tooth structure. A low knowledge score about dental veneers was significantly related to male gender (p < 0.001), non-Saudi nationality (p = 0.005), attending medium/high schools only (0.014), and working in jobs outside the dental field (p = 0.036). Conclusions: The public’s knowledge regarding dental veneers in Saudi Arabia is fair but requires improvement to correct some misconceptions regarding the benefits and risks associated with the installation of veneers. The defects in knowledge identified by the present study should be addressed in patient education initiatives to improve patients’ understanding, align patients’ expectations, and help informed decision-making.
