Teeth play an important role that cannot be ignored for the health of the human body. Teeth are subjected to the grinding of food, the harm of bacteria and the corrosion of acidic substances in the mouth every day. The human oral cavity is very prone to problems, so brushing teeth correctly is particularly important. It is also the basic method to maintain oral health. It can not only reduce the bacteria in the oral cavity, remove food debris, reduce the occurrence of dental caries and gingivitis, but also avoid damage to oral soft tissues. and dental hard tissue damage. So how many times a day to brush your teeth, when is the best time to brush your teeth?

 It is a good thing to pay attention to oral health, but blindly brushing your teeth multiple times will get twice the result with half the effort and cause certain damage and wear to the tooth enamel.

 The correct way to brush your teeth is:

 1. Brush your teeth in the morning

Calcium levels in saliva are lowest in the morning. Therefore, the risk of tooth damage from bacteria and acidic foods is highest during the day. After a whole night, bacteria have multiplied in the mouth. Brushing your teeth can speed up the secretion of saliva that was reduced the night before, and the fluoride in the toothpaste mixed with saliva can effectively slow down the acid damage.

 It only takes a few seconds for the bacteria to start metabolizing the sugar into acid. It's much wiser to clean up the bacteria before you eat than to brush your teeth after they've eaten a lot of sugar and produced acid.

 2. Brush teeth before bed

Compared with getting up early and brushing your teeth, brushing your teeth before going to bed is more important. It can remove food residues and dirt accumulated on your teeth during three meals a day.

 When a person falls asleep, the secretion of saliva will decrease, and saliva can wash away bacteria and inhibit bacterial reproduction. If you don’t brush your teeth or clean them before going to bed, food residues will soon ferment and produce acid under the action of bacteria. In addition, the lack of saliva in the mouth due to sleep cannot dilute and neutralize the acid produced by bacteria, and the teeth will be easily corroded. , may cause dental caries over time. So brush your teeth before going to bed, clean the food debris left between the teeth and the teeth, and do not eat anything after brushing, you can maintain oral hygiene throughout the night.

 3. Rinse mouth after meal

Gargling after meals is a very good habit, and long-term persistence is conducive to oral protection. Food residues are often left on the teeth, which breeds bacteria. If you rinse your mouth after a meal, you can effectively remove the food residues and avoid the growth of bacteria. In addition, after eating a lot of irritating food, there will be more serious breath, gargling can effectively reduce these irritating odors. It is recommended to rinse your mouth with warm water. Hot water and cold water are too irritating to your mouth. Secondly, rinse your mouth 3 minutes after eating. It is the best time to rinse your mouth for no less than 30 seconds each time.

 To sum up, I hope everyone can develop a good habit of brushing teeth. You can use an electric toothbrush instead of a hand brush to clean deeply and protect your teeth; eat less irritating and acidic foods to take care of our oral health.
