Desserts

Desserts are harmful to teeth mainly because of their high sugar content and sticky ingredients. Desserts such as cakes, biscuits and candies contain large amounts of sugar, which feeds harmful bacteria in the mouth that break down the sugar to produce acids that erode tooth enamel. In addition, many desserts contain refined carbohydrates, which can also exacerbate the acidic environment in the mouth. More importantly, certain desserts such as caramel and toffee, which are sticky sweets, adhere to the surface of the teeth and are difficult to remove by saliva flushing, increasing the risk of tooth decay. Therefore, while there is nothing wrong with enjoying desserts in moderation, it is important to maintain good oral hygiene habits, including regular brushing, flossing and regular check-ups at the dentist to prevent dental problems associated with desserts.

Carbonated drinks

Carbonated drinks are harmful to teeth in two ways: acid erosion and sugar stimulation. Firstly, carbonic acid in carbonated beverages will react with calcium, phosphorus and other minerals in saliva in the mouth to form acidic substances, leading to the dissolution of minerals on the surface of the teeth, which in turn causes demineralisation of tooth enamel and acidic caries. Secondly, the high content of sugar in carbonated beverages will provide nutrients for the bacteria in the oral cavity, promote bacterial reproduction, produce a large number of acidic metabolites, exacerbate the acidic environment on the surface of the teeth, accelerating the corrosion of teeth. Long-term consumption of carbonated beverages not only easily lead to enamel loosening, tooth surface becomes rough, but also increase the risk of dental caries and periodontal disease. Therefore, in order to protect dental health, it is recommended to reduce the intake of carbonated beverages, rinse your mouth in a timely manner after drinking, conduct regular oral examination and cleaning, as well as maintaining good oral hygiene habits.

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.
