Citrus fruits like oranges, lemons, limes, and grapefruits are acidic and can erode tooth enamel. The acid can weaken the protective enamel and make teeth more susceptible to decay.
Pineapple is another acidic fruit that can be harmful to teeth. It contains enzymes that can break down proteins, potentially affecting the oral tissues.
Dried fruits like raisins, dates, and apricots are concentrated sources of sugar. They are sticky and tend to cling to teeth, providing a constant source of sugar for harmful bacteria in the mouth.
Grapes, especially when consumed in large quantities, are high in natural sugars and can contribute to tooth decay. Their small size and the fact that they can easily get stuck between teeth make them even more problematic.
Kiwi is an acidic fruit that can affect tooth enamel if consumed excessively. While it's rich in vitamin C and other nutrients, it's best enjoyed in moderation.
Pomegranate seeds and juice are high in sugars and can be acidic, which can have a detrimental effect on tooth enamel.
