Coffee and citrus fruits are bad for teeth? These tricks should not be frightened.

Dentists suggest cleaning your teeth immediately after drinking coffee, or gargling with water after drinking coffee.

[6 major foods bad for teeth]

1. Coffee

Coffee is an acidic beverage, which is disadvantageous to tooth enamel for a long time. Coffee is a deeply pigmented drink, which is easy to deposit on the surface of teeth and form tooth stains. Enamel is easy to be eroded if it comes into contact with acid for a long time.

Dr. Huang Yaohui suggests that you should clean your teeth immediately after drinking coffee, or gargle with water after drinking coffee. When it is not convenient to clean your teeth, you can also consider chewing sugar-free gum for 5 to 20 minutes to stimulate saliva secretion and achieve a little "rinsing" effect. Reduce coffee stains, you can also use straws to reduce coffee retention time in the mouth, so that the color of coffee is not easy to stain the teeth.

two。 Acid citrus fruit

Citrus fruits such as oranges and tomatoes are acidic fruits. If they often eat acidic foods, the surface of their teeth will be slightly glossy, indicating that the teeth have been covered with acidic substances, increasing the risk of tooth decay.

3. Starchy snacks

Eating potato chips and other high-starch snacks are easy to get stuck in the teeth, and starch is also a hotbed of tooth bacteria, so you should brush your teeth after eating potato chips instead of going to bed without brushing your teeth, which will make the bacteria on your teeth active.

4. Sodas

People who like carbonated drinks should be careful that they may destroy your teeth. Carbonated drinks, as the name implies, is the addition of carbon dioxide gas to react with water to form "carbonic acid", resulting in the "bite" characteristics of most soft drinks. In addition to natural carbonic acid, including cola and soda, "phosphoric acid" is added, which gradually erodes the enamel of teeth, leading to tooth decay.

5. Dried fruit

Dried fruit usually sticks to its teeth, and because a large amount of sugar is added in the pickling process, it becomes an accomplice to tooth decay, so it is recommended that it is better to use natural fruit.

6. alcohol

Studies have found that alcohol can reduce saliva secretion, cause dry mouth, may also stimulate gingival tissue, affect cell division, and do a lot of damage to teeth.
