Teeth with plaque can be removed by brushing, oral irrigators, flossing and periodontal scaling. 1. Brushing: Brush your teeth correctly twice a day, morning and evening. When brushing, the toothpaste on the surface of the toothbrush and the plaque on the surface of the teeth are constantly rubbed together, which can remove plaque. It can remove the plaque attached to the surface of the teeth. 2. Oral rinser: The operation is mainly through the high-pressure water column on the surface of the teeth and the gap between the teeth for rinsing, so as to achieve the purpose of removing plaque. 3. Flossing: Flossing is also a good way to remove residues and plaque from between teeth. 4. Periodontal scaling: All the above methods have some effect on plaque, but they can’t remove it 100%. Periodontal scaling is also called scaling, which can effectively remove plaque through ultrasonic vibration. The appearance of plaque must be taken seriously, and take methods to remove it in time.
