2. Know how to protect your teeth.
(2) Activity preparation
A series of pictures about protecting teeth.
(III) Activity process
1. Guide children to compare and observe each other. Whose teeth are good and why?
2. Guide children to think and discuss: Why do some people have irregular, yellow, black and rotten teeth?
3. Introduce how to grow neat and beautiful teeth.
(1) When changing teeth, be careful not to loosen the teeth manually; Don't lick loose deciduous teeth and growing new teeth with your tongue; If the deciduous teeth don't fall out, new teeth will grow out. Please ask the dentist to pull out the deciduous teeth in time. At the same time, guide children to think and talk about why they should do this.
(2) Discussion: "Do you want to eat soft food when changing your teeth?" The teacher concluded: children don't have to eat soft food when changing their teeth. Eating coarse grains and crude fiber food at ordinary times can exercise teeth, strengthen roots, help straighten teeth, supplement calcium tablets and vitamin D, and help grow teeth.
(3) Always brush your teeth in the morning and evening. If the teeth are rotten and the roots are not well developed, grotesque permanent teeth will grow.
Look at the series of pictures and talk about how to protect our teeth.
(1) Don't eat sweet and sour foods before going to bed. They will destroy the protective layer of teeth and make them suffer from bacteria.
(2) Insist on brushing your teeth in the morning and evening, remove food residues in your mouth and teeth, and kill bacteria in your mouth.
5. Summary: Children will not change their teeth after changing their teeth, so children must protect their teeth.
