1. The benefits of brushing your teeth with your left hand

Recently, a British study confirmed that as long as you slightly change your lifestyle and do some active "brain exercises", such as brushing your teeth with the other hand, taking a bath with your eyes closed, doing crossword puzzles, etc., your intelligence can be improved by 10%-40% within 7 days. So brushing your teeth with your left hand can improve your intelligence.

2. The role of brushing teeth

Dental plaque is the initiating factor of periodontal disease, so the treatment of periodontal disease should first remove plaque and prevent the re-formation of plaque. During the basic treatment stage, the respective responsibilities of doctors and patients in the periodontal disease treatment process should be clarified. Doctors should try to eliminate or reduce factors that cause plaque retention, growth, and re-formation, affect patients' implementation of oral hygiene measures, and promote the progression of periodontal disease. Patients should be responsible for daily removal and control of supragingival plaque. Brushing teeth is the main means for people to remove plaque and prevent the occurrence, development and recurrence of periodontal disease.

3. How to brush your teeth

1. Place the brush head on the neck of the tooth, with the bristles pointing towards the root of the tooth (upward for maxillary teeth and downward for mandibular teeth). The bristles should be at an angle of approximately 45° to the long axis of the tooth. Apply slight pressure so that part of the bristles enters the gingival sulcus and part of the bristles is placed on the gums.

2. Start brushing your teeth from the buccal side of the back teeth, in groups of 2 to 3 teeth. Use short horizontal vibrations to move back and forth on the same area several times. Then turn the toothbrush toward the crown of the tooth and brush the cheek surface. After brushing the first area, move the toothbrush to the next group of 2 to 3 teeth and reposition it, making sure there is an overlapping area with the previous area. Continue to brush the next area, and brush the labial (cheek) surfaces of the upper and lower teeth in order.

3. Use the same method to brush the lingual (palatal) surface of the back teeth.

4. When brushing the lingual surface of the front teeth, place the brush head vertically on the tooth surface, so that the front bristles touch the gum edge, and vibrate from top to bottom. When brushing the lingual surface of the lower front teeth, vibrate from bottom to top.

5. When brushing the occlusal surface, point the bristles towards the occlusal surface and brush back and forth with a little force.
