Citrus fruits

Citrus fruits are harmful to teeth mainly because of their acidity and fructose content. Citrus fruits such as oranges, lemons and grapefruit contain a lot of vitamin C, but they are also highly acidic. Prolonged exposure to acidic environments can erode tooth enamel, leading to tooth sensitivity and even tooth decay. In addition, citrus fruits are rich in fructose, bacteria will use fructose to produce acidic metabolites, exacerbating oral acidification, further damaging teeth. Frequent consumption of citrus fruits or drinking citrus juices may increase the risk of tooth damage. To minimise damage to teeth, it is recommended to rinse and clean the mouth promptly after consuming citrus fruits or choose to consume them with other foods to reduce the amount of time the acids are in direct contact with the teeth. In addition, people with sensitive teeth may consider reducing their intake of citrus fruits, maintaining good oral hygiene habits and having regular oral check-ups to prevent potential dental problems.
