Do you have good teeth? We brush our teeth to keep them clean and healthy. In fact, having good eating habits is also helpful for the health of our teeth!

Eating too many sweets is the worst thing you can do to your teeth. When you eat candies, for example, the bacteria (细菌) in your mouth will produce some acids. These acids can damage your teeth and the tooth problems would appear. You can try eating sugar-free things instead of sugary ones. Chewing (咀嚼) xylitol gum, for example, can help reduce the bacteria in your mouth.

More or less, eating leaves food debris on your teeth. If you chew more while eating, the friction between your mouth and tongue will help you to better clear out the food debris. People often chew more when they eat high-fiber (高纤维的) foods, such as cabbage. When they eat low-fiber foods, such as white bread, they chew fewer times. Therefore, it’s a good idea to eat more high-fiber foods.

You may think it’s okay to eat ice cubes (冰块) because they’re just water. These cracks (裂缝) can then weaken (弱化) your teeth. While it may feel good to break up ice cubes with your teeth, it’s better to let them melt in your drink.

All in all, in order to have a brighter smile, you should improve your eating habits as well as brush your teeth twice a day. Also remember to floss (用牙线洁牙) and make sure to visit your dentist often!
