How to brush your teeth correctly?

The first paragraph: summary of content

Correct brushing is the basis for maintaining oral health, which mainly includes toothbrush selection, brushing posture, time control, use of auxiliary tools and frequency arrangement. First of all, choosing a soft-bristled toothbrush and fluoride toothpaste is key; secondly, using the Pasteur brushing method (gentle brushing at a 45-degree angle) can effectively clean the gingival sulcus; brushing twice a day for 2 minutes each time is the basic requirement, and it is recommended to use dental floss or a dental rinser to clean the interdental spaces. Finally, regular toothbrush replacement (every 3 months) and oral examinations are equally important. This article details these points step by step.

Paragraph 2: Choice of Toothbrush and Toothpaste

Quality brushing tools are the first step. RecommendedSmall head soft bristle toothbrush, to prevent the hard bristles from damaging the gums, and children can choose cartoon shapes to cultivate interest. Fluoride toothpaste can strengthen tooth enamel and prevent dental caries, but children under 6 years old need to use the low-fluoride version specially designed for children. Some brands such asColgate, Crest, Shukeetc. have related products. Be careful to avoid toothpastes with exaggerated claims such as "whitening" or "special effects", and choose according to your oral condition (for example, use anti-sensitivity models for sensitive teeth).

Section 3: Brushing postures and techniques

adoptPasteur brushing method: Tilt the toothbrush at 45 degrees and aim it at the gingival sulcus, vibrate horizontally in a short distance (amplitude is about 1-2 mm), and clean the outer surface, inner surface and occlusal surface in sequence. The American Dental Association (ADA) states that this method can remove 80% of dental plaque. Do not brush your teeth with force in a saw-like motion laterally to avoid wedge-shaped defects. The hard-to-brush areas of the back teeth can be replaced by the vertical brushing method, and the tongue surface also needs to be lightly brushed to reduce bacterial accumulation.

Paragraph 4: Time and Auxiliary Tools

Brush your teeth at least every time2 minutes, you can use the timer or the smart reminder of the electric toothbrush. The data shows:

Brushing time <1 minute	Plaque removal rate is only 40%
Brushing time ≥ 2 minutes	Plaque removal rate reaches 70%

Brush your teeth 30 minutes after a meal to prevent acidic substances from eroding tooth enamel. Floss once a day to clean the gaps between teeth that are difficult to reach with toothbrushes. Dental rinsers (such as Waterpik) are suitable for orthodontic patients.

Paragraph 5: Summary and reminder

Correct brushing requires a combination of tools, methods, and habits: choose the right toothbrush and toothpaste, adhere to scientific techniques and duration, and check regularly. The Chinese Stomatological Association recommends cleaning your teeth every six months to detect potential problems in time. Children need parental supervision until they are 7 years old, and the elderly can choose an electric toothbrush for labor-saving cleaning. Remember: brushing your teeth is just the basics. Comprehensive oral care also needs to be combined with diet control (less sugar) and quitting smoking and limiting alcohol.
