1. Is the electric toothbrush really more effective than ordinary toothbrushes?
Answer: Yes indeed. To understand this problem, you must first know the purpose of brushing your teeth. The most important thing for us to brush our teeth is to remove dental plaque, which is the root cause of a series of oral diseases such as tooth decay and dental calculus. A series of studies have been done at home and abroad, and the results show that compared with manual toothbrushes, using electric toothbrushes will reduce plaque by 21% and reduce gingivitis by 11%. Electric toothbrushes are indeed better than ordinary toothbrushes in terms of cleaning effect.
2. Why is the cleaning efficiency of electric toothbrushes higher?
Answer: This will start from the working principle of electric toothbrushes. The mainstream electric toothbrushes on the market are sonic electric toothbrushes. This kind of toothbrush mainly relies on a motor to drive the brush head to produce small amplitude high-frequency oscillations perpendicular to the direction of the brush handle. It then drives the water flow to wash the teeth to remove plaque and food residues. The oscillation frequency of sonic electric toothbrushes on the market is about 30,000 times per minute, and some high-quality toothbrushes can reach 38,000 times per minute. The efficiency is about 170 times that of manual toothbrushing, and the cleaning power is naturally better. Ordinary toothbrushes are much higher.
Another point is that the brush heads of electric toothbrushes are generally relatively small. Many people find it difficult to brush their teeth. But in fact, this small brush head can better clean dead corners, such as between teeth, gingival sulcus, and large back teeth. Larger ones tend to “out of reach” these small gaps.
3. How should an electric toothbrush be used?
Answer: In fact, whether you use an electric toothbrush or an ordinary toothbrush, I recommend using the Pap method to brush your teeth. This method is a more scientific method of brushing recognized in the industry. The core is to tilt your toothbrush so that the bristles and The tooth surface forms a 45-degree angle, aligning with the position of the gum base. This is mainly because dental plaque is very easy to grow in the middle and lower third of the teeth near the gums, even in the gap between the teeth and the gums, which is what we usually call the gingival sulcus, so we usually brush our teeth At this time, only when the bristles are inclined at 45 degrees can the plaque be effectively removed.
