Dear leaders, teachers and students,

Good Morning, everyone! The theme of my speech today is: protect your teeth, starting with me. As we all know, a smile is the most beautiful symbol in the world, and teeth are the center of a smile. It can be seen that having good teeth, especially white and neat teeth, is what everyone expects and will undoubtedly make your smile brighter and more confident. Because the beauty of teeth directly affects our daily communication and external perception.

This happened in Guangdong: a manager talked with foreign businessmen about business, which was a foregone conclusion, but no agreement was reached in the end. Only afterwards did I know that the problem was with the manager. He usually doesn't pay attention to oral hygiene, and his mouth is full of black and yellow teeth, which gives a bad impression. In the eyes of foreign businessmen, can a manager who can't even do his own oral hygiene well do a good job in an enterprise?

We are in a critical period of growth and development, and the quality of teeth can directly affect our physical and mental health. So we should try our best to protect our teeth from bacteria.

Three generations of gentlemen. Every parent expects us to have a healthy life and a high quality life. Then, let's "take care of our teeth and prevent dental caries" from now on.

However, students, it is better to do more activities by yourself. The best way to protect your teeth is to do three things:

1. Brush your teeth every morning and evening; 2. Use a healthy toothbrush; 3. It is best to use fluoride toothpaste.

Next, I will take you to learn the correct method of brushing your teeth. The toothbrush vibrates horizontally for 4-5 times in its original position, and only moves about 1 mm when it vibrates, and then brushes vertically along the teeth. When brushing the upper teeth, brush from top to bottom, brush from bottom to top, brush the chewing surface, brush back and forth, brush the tongue surface of the upper and lower teeth, and you can stand the toothbrush head up and down. Move the toothbrush to the adjacent teeth in turn and repeat the same action. When brushing your teeth, you should follow a certain order, and every time you move the toothbrush, you should have a proper overlap to ensure that every tooth surface is not missed. Brush your teeth twice in the morning and evening for 3 minutes each time.

We should also develop good eating habits. Eat sugar scientifically, drink less carbonated drinks, and don't eat after brushing your teeth before going to bed; Avoid eating too many sweets, and don't "bully the weak and be afraid of the hard". Eat more vegetables that can promote chewing, such as celery, cabbage, spinach, leeks, kelp and so on. , as well as meat, eggs, milk and some nuts with high calcium content, stimulate the synchronous development of jaws and teeth.

Students, I hope everyone can learn to protect their teeth. I hope everyone has healthy teeth and a beautiful smile.
