Eating lemons can help whiten teeth to some extent due to their acidic nature. The acid in lemons acts as a mild bleach that helps remove surface stains from teeth. However, it is important to note that consuming too many lemons can erode tooth enamel, so it is important to be careful about the amount you consume.

Besides their potential teeth whitening properties, lemons are also a good source of vitamin C, which is important for gum health and overall oral health. Vitamin C also helps strengthen the immune system and is important for healthy skin.

It is recommended to consume lemons in moderation as part of a balanced diet. Drinking half a lemon a day or adding lemon juice to water or salads can provide the benefits of vitamin C without the risk of potential tooth enamel erosion. It is also important to rinse your mouth with water after eating lemon to minimize possible damage to your teeth.
