A plant-based diet emphasizes the consumption of foods of plant origin—fruits, vegetables, legumes, whole grains, and nuts. This dietary pattern may provide oral-health benefits due to its fiber, antioxidant, and micronutrient content. However, it may also present potential risks, such as increased exposure to acidic foods or fermentable carbohydrates. Understanding these factors helps promote balanced habits that support the prevention of dental caries, erosion, and periodontal disease.
