Year: 2026
Type: article
Study design: Observational Study
Abstract: Introduction: Over-the-counter (OTC) teeth whitening products are widely accessible and commonly used without professional supervision. However, public knowledge, attitudes, and practices regarding these products remain insufficiently explored in Saudi Arabia. Methods: A cross-sectional survey was conducted using a self-administered questionnaire distributed via social media platforms. A total of 420 adults participated. Data were analyzed using descriptive statistics and chi-square tests to assess associations between demographic variables and whitening-related knowledge, attitudes, and practices. Results: Awareness of OTC whitening products was high (93.8%), with 53.6% reporting prior use. Whitening toothpaste was the most commonly used product (51.4%). Tooth sensitivity was the most frequently reported side effect (39%), while gingival irritation was less common (4.9%). Despite this, only 5.7% perceived OTC whitening products as posing health risks. Neutral satisfaction was reported by 46.6% of participants. Social media was the primary source of information (43%), and tooth color concern was the main motivation for use (45.4%). Conclusion: Although awareness of OTC whitening products is high, perceived health risks remain low despite frequent reports of adverse effects. These findings highlight the need for increased professional guidance and public education regarding the safe use of OTC whitening agents.
