The most harmful products for teeth are:
1. Sweet drinks.
Sugary soda contributes to the accelerated destruction of tooth enamel. This effect is due to the content of sweet drinks in them large amounts of sugar and citric acid, because of which the enamel is destroyed. Citric acid dissolves calcium salts included in the teeth. A sugar - pure carbohydrate acts on microorganisms in the oral cavity which produce acids, also destroys the enamel.
2. Candy.
All candies contain sugar, so they are harmful to the teeth. The most harmful ones are toffee, caramel and candy. They are located in the mouth long enough, so have time to harm the teeth more than, say, a chocolate bar.
3. Milk.
Carbohydrate found in milk - lactose harmful to teeth because it also destroys tooth enamel. As in the case with a conventional sugar, because of the use of milk in the mouth creates a favorable environment for the growth of bacteria that produce acid destroys the enamel.
4. Some fruits and vegetables.
Unfortunately, many fruits and vegetables, too bad teeth. For example, citrus fruits and tomatoes contain citric acid, grapes and sweet apples - a lot of sugar and potatoes and bananas - a significant amount of carbohydrates.
Based upon the foregoing, the question arises, how do you maintain healthy teeth? You can, for example, to refuse or limit the use of sweet drinks and candy. But do not do just as well with milk and fresh fruit and vegetables, because they must be present in the diet in order to maintain the health of the entire body.
Just in this case it is necessary to minimize the damage. Fruit juices, for example, it is better to drink through a straw. This minimizes the effect of citric acid on enamel. Also, after every meal, it is desirable to rinse your mouth with clean water.
But brushing your teeth immediately after eating is not as useful as many are accustomed to think. Acids softened tooth enamel is very vulnerable, so brushing your teeth will cause more damage to it. If you want to brush your teeth after eating, you need to wait for half an hour, or even better an hour.
