As long as the brushing posture is correct, the electric toothbrush and ordinary toothbrush are equally effective. However, if the brushing method is not mastered, the consensus among studies is that electric toothbrushes do provide better cleaning results.

There is such a meta-analysis, summed up the last 5 years, over 50 comparative studies, it summed up the electric toothbrush has several major benefits, you can also see if you are suitable.

Firstly, electric toothbrushes are more efficient in cleaning. Within the same timeframe, the cleaning effect of an electric toothbrush is dozens of times stronger than manual brushing, and can better clean the surface of the teeth and the crevices, as well as some hard-to-reach areas.

This cleaning efficiency is bound to give you the benefit of saving time and effort. Two minutes with an electric toothbrush is equivalent to more than ten minutes of manual brushing, so it's more suitable for busy individuals. If you're like me, constantly reminding your child and struggling to have them brush for the full three minutes, then an electric toothbrush might be an effective option to help you reduce parent-child battles a little.

Secondly, an electric toothbrush can relieve pressure on your gums. It can reduce the pressure brought to the gums by braces and prevent gum recession, so it is very suitable for people who wear braces and orthodontics.

Third, the electric toothbrush can eliminate surface stains, such as coffee stains, tobacco stains, tea stains, inhibit the formation of dental calculus, and can effectively whiten the teeth if used consistently. If you have whitening needs, it is also very suitable.

Fourth, controlled brushing. The vibration frequency of the electric toothbrush is consistent, and the pressure control is more precise. If you use ordinary toothbrushes always have a bad grasp of the strength, brush lightly, plaque is not cleaned down, and brush heavily damage enamel or gums. If you have this kind of trouble, then you are also very suitable for an electric toothbrush.

Of course, the electric toothbrush is not everything, there are two cases where it’s not ideal. One is, that if the child is relatively small and can't master the use of an electric toothbrush, it is easy to damage the tender gums. If the child says it is not comfortable, then do not use it. Secondly, if you happen to have acute gingivitis and are experiencing significant bleeding, it is not suitable for electric toothbrushes either, as the high-frequency vibrations is too high, and there may be a risk of further aggravating the damage.

How to choose an electric toothbrush? In comparison, it's even simpler than a regular toothbrush, as long as it has a tolerable vibration mode, is not uncomfortable, and has a brush head size that cleans every one of your teeth, you're good to go. After all, it's electric, so a higher waterproof rating would be nice. As for any sync apps, Bluetooth connection, display, and charging method, none of them are particularly important points.
