Unlike a conventional brush head, an electric brush attachment softens plaque and then literally sweeps it off the tooth enamel. It pulsates and makes thousands of reciprocating and rotating movements per minute. You can choose between three to five modes of use. The main ones are:
- daily cleaning,
- gentle cleaning,
- polishing of tooth enamel.
For a thorough cleaning, choose a round or oblong nozzle. The bristles should be of different lengths, with rounded tips and directed towards each other. These thoroughly cleanse and do not injure the gums and tooth enamel.
Advanced electric brushes clean not only with bristles, but also with sound.
How to choose an electric toothbrush
The cleaning head for mechanical electric brushes is round. During the cleaning process, it turns left / right at an angle of 40-70 degrees. The number of movements depends on the model - from 5,000 to 40,000 per minute. Advanced devices are equipped with a ripple mode.
- Benefits: reasonable cost of the device and high-quality teeth cleaning.
- disadvantages: can not be used for gingivitis and periodontitis.
She has an elongated shape. The device operates at a frequency of 200-400 Hz, it is quite noisy. Using sound vibrations, the toothpaste is mixed with water and saliva. It penetrates the gaps between the teeth and cleans out dirt. The bristles make 24-48 thousand movements per minute and easily loosen plaque on the teeth.
- Benefits: long-lasting freshness in the mouth.
- disadvantages: painful sensations with diseases of the gums and teeth.
How to choose an ultrasonic toothbrush
A piezoceramic plate inside the cleaning head generates ultrasound and vibrates the brush bristles at a breakneck speed. Depending on the model, they perform from 2.4 to 204 million movements per minute at a frequency of 0.02 to 1.7 MHz, but the amplitude of these movements is not large. Our hearing does not pick up such a frequency, but it is more than enough for a thorough brushing of our teeth.
With the help of an ultrasonic brush, you brush your teeth without moving, simply by bringing it to your teeth. Ultrasound forms millions of microbubbles in the toothpaste, which remove food debris from the irregularities of the enamel and whiten it. It also destroys bacteria on the gums. But if you have filled teeth or have crowns, it is better to refuse an ultrasonic brush. The sound wave is refracted between the dental tissue and the filling material. It speeds up the spread of the infection.
- Benefits: maximum efficiency of cleaning teeth and massage of the gums with ultrasound.
- Disadvantages: do not use the ultrasonic nozzle for people with oral diseases and treated teeth. Under the influence of ultrasound, fillings, crowns and other bodies foreign to teeth are destroyed at an accelerated rate. Pregnant women and people with pacemakers should not use it.
How to choose a toothbrush for a child
The children's brushes are lightweight and have a shortened handle. They are bright, often in the form of figurines of fairy-tale characters, so that, while playing, the child gets used to brushing his teeth with pleasure. The main feature of children's models is that a whisk bristle, similar to a broom brush, is installed in the cleaning heads. The villi are soft but firm. Such a brush will not damage the delicate enamel of milk teeth.
The smaller the child, the softer the bristles of the brush head should be. Manufacturers indicate the age on the packaging for which this model is designed.
- Children under five years old should buy models with the “extra soft” mark (very soft).
- Senior - "soft" (soft).
Switch to an "adult" electric brush should be at the age of 12-14 - when the teeth are finally formed.
How to brush your teeth with an electric toothbrush
Place the brush on the teeth at a 45 degree angle for 1-2 seconds, then move to the next area. Remember to clean the chewing surfaces and back walls.
How to choose the right electric toothbrush
The more autonomy, the better
- The brush should be able to work for 1 to 2 weeks. Choose a model with a charge indicator. Then the device will not turn off without warning at the wrong time.
- Batteries are expensive: they are not cheap, and we don't have enough charge for a long time.
Do not be guided by unnecessary cleaning modes
The more "bells and whistles" a brush has, the more it will cost you. Before buying, check with your dentist about the functionality you need. At least 50% of reviews on the Internet boil down to one thing: "I took a full minced meat, but I use 1-2 modes."

The more of them in the set, the more versatile dental care. They are more expensive individually.
- for gentle cleaning of teeth,
- for bleaching and polishing,
- to clean the interdental spaces,
- for sensitive gums,
- for daily care,
- for children's teeth).
If you buy your own brush head for each household, the whole family can use one electric brush. Each nozzle has its own colored sealing ring, with its help you can easily find out who it belongs to (each has its own color).
The bristles of the cleaning head wear off over time and change color. This is a signal: it's time to change the nozzle. On average, it lasts from 3 to 6 months.
Need a timer and pressure sensor
- The timer displays how long it takes to brush each segment of the dentition.
- The sensor monitors the force of pressing on the teeth. You should not be overzealous: you can damage the enamel.
