Brushing teeth is an important way for people to keep their mouths clean and healthy in daily life. A white tooth can make our smile more beautiful. A study by American scientists has found that people who do not brush their teeth well not only have yellow teeth, which affect their beauty, but also lose 13 years of life what is the right way to brush your teeth
1. Place the brush head on the tooth neck, and the bristles point to the root direction (the maxillary teeth are upward and the mandibular teeth are downward). The bristles are at an angle of about 45 ° with the long axis of the teeth. Press slightly to make the bristles enter the gingival sulcus and rest on the gums.
2. Start brushing from the buccal side of the back teeth in a group of 2-3 teeth. Use the action of short-distance horizontal vibration to go back and forth in the same part for several times, and then rotate the toothbrush towards the crown to brush the buccal surface. After brushing the first part, move the toothbrush to the next group of 2-3 teeth for repositioning, pay attention to the overlapping area with the previous part, continue to brush the next part, and brush the lip (cheek) surface of the upper and lower teeth in sequence.
3. Brush the lingual (palatal) surface of the posterior teeth in the same way.
4. When brushing the lingual surface of the anterior teeth, place the brush head vertically on the tooth surface so that the front bristles contact the gingival margin and vibrate from top to bottom. When brushing the lingual surface of the anterior teeth, it vibrates from bottom to top.
5. When brushing the occlusal surface, the bristles should point to the occlusal surface and brush back with a little force.
Many people don’t brush their teeth for too long, but brushing is by no means routine. According to the survey, 60.4% of people brush their teeth for 1-2 minutes, 23.8% for less than 1 minute, and only 15.8% for more than 2 minutes. Some experts say that brushing time is not long enough, and brushing is also equivalent to white brushing in addition to its massage and cleaning functions, toothpaste also has sterilization and other health care functions. If the toothpaste does not have sufficient contact with teeth and the contact time is too short, it will not be able to give full play to its functions. Therefore, it is better to brush teeth for more than two minutes each time, so as to keep teeth in a high concentration of fluorine environment and improve the anti decalcification and anti caries ability of their surfaces. At the same time, correct brushing time also requires good brushing habits to keep teeth beautiful:
1. Brush your teeth in the morning and evening
“Toothbrush should be the last thing your teeth touch before going to bed.” Edmond R. Hewlett, a professor of Dentistry at UCLA, said that eating snacks before going to bed can significantly increase the risk of tooth decay. Brushing your teeth in the morning is also important: when you sleep, the protective saliva will slow down, which will stimulate the bacteria in your mouth to reproduce faster. Generally speaking, brush your teeth twice a day for more than two minutes each time, ensuring that there is 30 seconds for cleaning in every corner.
2. Choose soft brush for toothbrush
Dr Hewlett pointed out that the soft toothbrush can gently slide your gum tissue and then brush away any plaque that stays there. If the plaque here is not completely cleared, it will increase the risk of gum disease. Choosing a toothbrush with medium hardness or too hard will make it difficult to clean the tartar between teeth and hidden surfaces. Instead of good cleaning effect, it is more likely to cause tooth decay. And because of excessive force, it will also lead to gingival bleeding, injury and even atrophy.
3. Brush your tongue too
The tongue also harbors a large number of harmful bacteria. There are many tiny papillary processes on the back and side of the tongue, and food and debris can be easily stuck in their gaps. That’s why you need to wash your tongue every day.
4. Change the toothbrush regularly
An average toothbrush contains more than 10 million bacteria, so the old toothbrush can not effectively remove dental plaque or bacteria. The American Dental Association recommends that you change your toothbrush every 3-4 months. If you are sick, you must change your toothbrush immediately, because the bacteria and disease viruses left on it will attach to the toothbrush and infect you again.
