Background Molar-Incisor Hypomineralization (MIH) is a prevalent clinical condition which is associated with a high burden of disease. The present study aimed to assess and compare the knowledge, perceptions, and clinical experience of general dental practitioners (GDPs), pediatric dentists (PDs), and other dental specialists (DSs) in Egypt about MIH. Methods Online and paper-based survey administration methods were used to collect the responses from Egyptian dentists regarding their knowledge, and perceptions about MIH. The survey tool focused on participants’ socio-demographics, clinical experience, perceptions, clinical management, and preferences for further training. The level of knowledge regarding MIH was compared among the three groups. Data analysis utilized Chi-square and one-way ANOVA followed by Tukey’s post hoc test using SPSS® Statistics Version 26. Results The majority of respondents had observed MIH in their practice (86%). The participants who had a postgraduate degree had a significantly higher knowledge score value (51.01 ± 5.74) than GDPs (43.05 ± 7.04) ( p  < 0.001). PDs (51.13 ± 4.76) had a significantly higher knowledge score value than other DSs (50.91 ± 6.46) ( p  < 0.001). Conclusions Dissemination of evidence on MIH to dental practitioners especially to GDPs is highly needed to assure confidence in MIH diagnosis at an early stage when it can be best managed.
