Is a rotary electric toothbrush better than a sonic electric toothbrush? Are electric toothbrushes really more useful than ordinary toothbrushes?

The main function of an electric toothbrush is cleaning, which can make teeth cleaner, but it cannot whiten teeth. There are two types of electric toothbrushes: rotary and sonic. Which one do you think is better?

Is a rotary electric toothbrush better than a sonic electric toothbrush?

Rotary and sonic are the two major types of electric toothbrushes. It is impossible to judge which one is better. Next, we will compare them from three aspects, and you can choose the type of electric toothbrush that satisfies you.

1. Cleaning power comparison: Rotary electric toothbrush slightly wins

In terms of vibration frequency data and the contact area between bristles and teeth, rotary electric toothbrushes are relatively better, but the difference is not big. Both can clean our mouths well.

2. Comparison of the degree of wear on teeth: Rotary type wears more obviously, while sonic type protects teeth better

Data shows that rotary electric toothbrushes cause 4-5 times more wear on teeth than sonic toothbrushes on average. They rotate very fast and cause more wear on teeth. From this perspective, sonic toothbrushes are safer for our teeth. The difference in wear between sonic and rotary toothbrushes becomes more apparent after using them for a long time.

3. Brushing experience comparison: Sonic brushing is more comfortable

In terms of comfort, the difference between the two is quite big. Just search and you will know that there are many reviews that call the rotary toothbrush a "small electric drill". This is because the vibration of the rotary toothbrush is relatively large when used, and it is more likely to cause bleeding gums. In comparison, the sonic toothbrush works more gently than the rotary toothbrush. In addition, the noise generated by the rotary toothbrush is relatively loud when working, which may make people who are sensitive to sound feel uncomfortable, while the sonic toothbrush is quieter.

Are electric toothbrushes really better than regular toothbrushes?

It is true. The common sonic electric toothbrushes on the market do not clean teeth by emitting sonic waves, but are named because the vibration frequency of the toothbrush exceeds 260Hz, reaching the sonic frequency range that can be heard by the human ear. The number of vibrations per minute of electric toothbrushes generally reaches more than 30,000 times. In contrast, manual brushing generally has about 200 times per minute. The gap is as much as 150 times. The high-frequency vibration of the electric toothbrush will also stir up the foam of toothpaste and water flow to pass through the teeth for cleaning. Electric toothbrushes also have the advantage of a smaller brush head, which can deeply clean the hard-to-reach places such as the back of wisdom teeth and the inside of the front teeth, and achieve better cleaning effects when it is difficult to exert force when holding the toothbrush handle at an angle. According to research data from authoritative institutions, after three months of use, users of electric toothbrushes have 21% less dental plaque than those who brush manually, and 11% less gingivitis. It can be seen that electric toothbrushes do have huge advantages in cleaning power.

Can an electric toothbrush and an oral irrigator be used together?

Yes. Oral irrigators and electric toothbrushes can be used together. Brushing is the main way to clean teeth, while oral irrigators are auxiliary tools. Using the two together can better and more effectively remove dental plaque on the surface of teeth and food residues and bacteria in the gaps between teeth that cannot be cleaned by toothbrushes. Using them together can keep the mouth fresh, reduce and prevent the occurrence of periodontal diseases, and better maintain oral health.

Which should I use first, an electric toothbrush or an oral irrigator?

It is recommended to brush your teeth first. If you want to use an oral irrigator and an electric toothbrush at the same time, it is recommended to brush your teeth first and then use the oral irrigator. In this way, the dental plaque and bacterial substances removed from the tooth surface during brushing can also be washed away by the water column pressure of the oral irrigator, thereby better maintaining oral health. In addition, you can also use the oral irrigator when you don't need to brush your teeth after a meal, which can effectively remove food residues stuck in the teeth.
