What's going on here? This is the content of Chen Fa's circle of friends:
"In the two years when I wore braces, I followed the doctor's advice, brushed my teeth well, tried to brush my teeth, and brushed my teeth as long as I ate. Three minutes is nothing, but five minutes is not enough. The moment I saw the teeth again, the doctor praised that there were no calculus, and the teeth were not very yellow, clean and rare. I am proud to keep my unique brushing method to this day. Recently, I feel my teeth are extremely sensitive, so I can only swallow them in a hurry. I always thought that it was due to insufficient cleaning of teeth that caused tartar residue. Go to the stomatology department, lie down and be scolded by the doctor when you open your mouth. " You still think it's not clean enough? Your gums have been brushed off and your roots are exposed. "
It is reported that Chen Xiao has developed the habit of "brushing your teeth hard" since she corrected her teeth in her teens. She brushes her teeth at least twice a day for 5 minutes each time. After more than ten years of unremitting efforts, her teeth were finally brushed.
Moreover, she also has her own "unique brushing method": "At that time, the doctor asked me to brush sideways, but I felt weak when brushing. I know that brushing my teeth horizontally will do harm to my teeth, so I brush my teeth vertically, which will make me energetic. "
Incorrect brushing method+exaggerated strength+more than ten years, finally Xiao Chen's teeth were brushed by himself. After the dentist's examination, it was found that there were only two unfilled teeth left in the whole mouth.
Why did Xiao Chen do so much harm to his teeth by brushing his teeth? "Clinically, this disease is called wedge-shaped defect, which is a defect of dentin exposure caused by slow consumption of hard tissues of teeth lips, cheeks and neck, and is often wedge-shaped. Dentin is exposed when the enamel in the neck of a tooth breaks. When the dentin is also brushed off, the nerve part at the root of the tooth is exposed, which is also the cause of dentin allergy.
There are usually three reasons for this result:
1, wrong brushing method:
Brush horizontally or vertically for a long time. The correct way to brush your teeth is to brush your teeth with paper.
2, drink drinks as water all the year round:
Acidic substances in drinks will react with calcium in enamel and dentin. In the long run, calcium will be taken away by drinks.
3. Brush your teeth immediately after meals:
Tooth enamel will soften when it comes into contact with acidic substances, and it will wear easily if you brush your teeth immediately. It is generally recommended to brush your teeth 30 minutes after meals until the pH in your mouth is balanced.
Brushing points:
Point the toothbrush at an angle of 45 to the long axis of the teeth in the apical direction (the maxillary teeth are upward and the mandibular teeth are downward), and press the gingival-tooth interface area, so that one part of the bristles will enter the gingival sulcus, and the other part will spread out on the gingival margin and extend into the adjacent gap as far as possible. With a slight pressure, the bristles will vibrate horizontally in the back and forth direction for 65,438+00 times. When vibrating, the toothbrush only moves about 1mm and brushes 2 ~ 3 teeth at a time.
In addition, the intensity of brushing teeth is generally the intensity of brushing teeth with three fingers, and you can feel it yourself. Change your toothbrush every three months.
