7 tips for brushing your teeth
1. Don't brush your teeth with the first glass of water from the tap in the morning.
You'd better not drink the first glass of water. More than two-thirds of faucets have excessive heavy metal precipitation, so it is advisable to leave them for a period of time before entering the water for more than ten seconds.
2. It is best to choose a soft toothbrush.
Hard nylon toothbrush has a good effect on brushing off dental plaque and rust on tooth surface, but it is easy to damage enamel on tooth surface after long-term use. Soft nylon toothbrush has relatively little damage to enamel.
3, toothpaste should use fluoride.
Brushing teeth with fluoride toothpaste is the most effective method to prevent dental caries, which can reduce the incidence of dental caries by 20% ~ 40%.
4. The more common toothpaste, the better.
If there are no diseases or serious lesions in the mouth and teeth, it is recommended to choose traditional ordinary toothpaste. Because ordinary toothpaste mostly contains ingredients for preventing and treating oral diseases, it does little harm to teeth.
5. Toothpaste often changes brands.
Changing the type of toothpaste frequently can maintain normal oral flora and is beneficial to dental health.
6. You have to brush your teeth if you have no teeth.
Brushing teeth is not only to clean the surface of teeth, but also to clean the whole oral environment, such as the surface of gums and tongue. Although the teeth have fallen out, the mucosa, gums, alveoli and other tissues are still there. Therefore, it is necessary to clean the entire oral environment on time.
7. Don't brush your teeth immediately after eating sour food.
If you have just eaten acidic foods such as strawberries, don't brush your teeth immediately. Because oxalic acid and benzoic acid contained in acidic foods such as strawberries can decalcify the tooth surface and reduce the hardness of the tooth surface, brushing your teeth immediately will cause damage to the tooth surface, and over time, it will easily cause tooth allergies.
Little dentist
September 20th is the 30th "national love teeth day". With the coming of "Love Teeth Day", on the morning of September 15, our reporter Shao Tongshe walked into Yameijia Stomatological Hospital to learn about teeth and learn how to protect them.
After the assembly, everyone went to the classroom. After we sat down, a dentist began to teach us. She introduced the function of teeth: teeth can not only chew food, but also help pronunciation. Good teeth can also bring beauty. Teeth are also divided into incisors, fangs and molars, each with "eighteen martial arts". When eating, front teeth are used to chop food, fangs are used to chop food, and molars are used to grind food. Then she told us about teething, changing teeth, protecting teeth and other knowledge points. Through her explanation, we realized the importance of teeth and the ways to protect them. "Eating coarse grains and drinking milk is good for dental health; And brush your teeth with paper, at least twice a day ... "She gushed on the stage, and we listened with relish below, sometimes writing at the bottom.
Next, let me give you a quick answer. No matter what the topic is, I always take the lead and blurt out the answer. It is because of my concentration and self-confidence that I have become an out-and-out "prize harvester".
After answering first, we began to check our parents' teeth. Mother was lying in a chair, and the dentist taught me to examine her. I don't know until I check. I was shocked when I checked. It's incredible that my mother has so many problems with her teeth after passing the examination.
Through this activity, I realized the importance of teeth and benefited a lot. Students should protect their teeth, get into the habit of brushing their teeth at ordinary times and pay attention to oral hygiene, because teeth are our good friends for life, please be kind to them!
