The electric toothbrush has long since replaced the classic manual toothbrush. In particular, the sonic toothbrush is becoming increasingly common in bathrooms.
Because it not only cleans more deeply, but is also more comfortable, more hygienic, and easier to use. But how exactly does a sonic toothbrush work, and what is the secret to its success?
What is a sonic toothbrush?
A sonic toothbrush is an electric toothbrush. It cleans teeth using extremely rapid movements. These movements are performed so quickly that they are perceived only as vibrations while brushing your teeth.
More specifically, the head of the electric toothbrush must oscillate between 30,000 and 62,000 times per minute for the model to be called a sonic toothbrush.
Usually, sonic toothbrushes are powered by an integrated rechargeable battery. This lithium-ion battery is rechargeable and offers up to six weeks of battery life in higher-quality models.
The sonic toothbrush can also be easily transported without its charging station or taken with you on vacation. Battery-powered sonic toothbrushes are also available.
These modern toothbrushes are often equipped with various features, such as pressure control and different cleaning programs. Premium models generally have a Bluetooth function. This allows the sonic toothbrush to be connected to a smartphone. The manufacturer's app can be used to monitor brushing progress or access other controls.
Children are often offered challenges to make brushing their teeth an exciting and rewarding experience.
How does a sonic toothbrush work?
Sonic toothbrush technology is based on 30,000 to 62,000 lateral bristle oscillations per minute. The resulting vibrations provide an extremely effective cleaning effect.
Unlike a manual toothbrush, the brush head does not move up and down but glides over the teeth. The bristles are so fine that they vibrate one hundred times faster than those of a manual toothbrush.
The sonic toothbrush reaches its extremely high frequency by using a sound transducer instead of an electric motor. This generates the vibrations, which are then transmitted directly to the brush head.
The teeth are then cleaned by moving the brush head through sound. The sound waves generated and the associated fluid flow, in turn, offer the advantage that even hard-to-reach interdental spaces can be cleaned thoroughly.
In addition, the sonic toothbrush does not require pressure while brushing. Due to the high-frequency up-and-down movement, no effort is required. Some toothbrushes have 3 sonic vibration modes: gentle, normal, or intensive. This is the case with the Y-Brush toothbrush , which also allows you to brush your teeth in 10 seconds.
The difference between sonic and ultrasonic toothbrushes
The main distinguishing feature of sonic toothbrushes is that their brush head vibrates at high speed. You will therefore experience a completely different brushing sensation from that of models based on oscillation. In addition, sonic models do not emit ultrasound. Their main characteristic is that the brush head moves at high speed, and the rapid movement it makes produces the sound. Ultrasonic toothbrushes, on the other hand, use both a sonic vibratory movement of the brush head and ultrasound in a frequency range of 1.0 to 3.0 MHz. Ultrasound enables effective tooth cleaning, as well as a reduction in gum bleeding and the effective removal of bacterial plaque.
What are the benefits of the sonic toothbrush function?
The vibrations of a sonic toothbrush clean both the surface and sides of the teeth thoroughly and gently. This type of device ensures that even hard-to-reach interdental spaces are freed from plaque and bacteria.
Since minimal pressure is required, the gums are not irritated. This therefore considerably reduces the risk of gum inflammation.
This type of brush also provides greater comfort, because the toothbrush only needs to be held against the teeth and no scrubbing motion is necessary. This is particularly helpful for people with limited mobility or for children.
Sonic toothbrushes: who are they for?
Overall, sonic toothbrushes are designed for the vast majority of people to use, including people with oral and dental problems.
For people with sensitive gums:
Many sonic toothbrushes have special sensitive modes and brush very gently.
However, it is best to discuss this with your dentist beforehand, as they will be better able to assess the condition of your teeth and advise you on the type of brush suited to your needs.
For people with fillings or implants:
Implants also benefit from more thorough cleaning with sonic toothbrushes.
It is best to use a regular manual toothbrush immediately after intensive dental treatment and then switch to a sonic toothbrush afterward.
For people with braces:
Be aware that special accessories are even available for each type of orthodontic appliance.
The brush head does not move and is ideal for use with these appliances because it cannot get caught in the metal wires. Unfortunately, genuine sonic toothbrushes of this type are more expensive to purchase than more conventional ones.
In short,
Sonic toothbrushes are particularly effective and suitable for every type of dental problem. It is worth knowing that most manufacturers recommend sonic toothbrushes from the age of 12. However, specific models are also available for children aged 4 to 6.
