Frequently asked questions (FAQ)

Sonic toothbrush

What is the best way to use the mate sonic toothbrush?

1. Apply a pea-sized amount of toothpaste to the brush head.

2. Press the power button to select the desired brush mode. Press once for pink light, twice for blue light, three times for green light.

3. Tilt your mate by approx. 45 degrees. Position it half on the gum, half on the tooth. Start on one side at the back of the molars.

4. Now guide the brush head slowly along the rows of teeth. Always from the gums to the tooth. There is no need to make a circular brushing motion.

5. Do not exert any pressure. A light touch on the gums and teeth is sufficient. Pressure damages teeth and gums.

6. Every 30 seconds, the toothbrush gives a light vibration pulse to indicate that you should now brush the next quarter.

7. The cleaning program ends automatically after 2 minutes. Now rinse the bristles under running water. Remove toothpaste residue from between the bristles by lightly brushing your thumb through the bristles. Then dry the toothbrush with a cloth.

Important: Long-term contact with water and toothpaste residue can cause the charging contact underneath the toothbrush to rust. To prevent this, wipe the underside of the toothbrush with a dry cloth after use.

How do I clean and care for the sonic toothbrush?

The mate is a high-quality sonic toothbrush. You should treat it with care to enjoy it for a long time.

The following care tips will help:

1. Rinse the bristles well after each brushing. Hold it under running water and run your thumb through the bristles. This will remove the toothpaste that sits between the bristles.

2. Dry the sonic toothbrush with a towel after each brushing. Please make absolutely sure that the underside of the toothbrush always remains clean and dry. This is where the magnetic ring is located, which you use to charge the toothbrush in the charging station.

3. Store the mate sonic toothbrush in a clean and dry place. Please do not simply place it in a toothbrush cup. Water and toothpaste residue will collect in the bottom of the cup. If the mate stands in such an environment, the loading ring may rust. Please avoid this at all costs.

How does it work with the sound waves?

The vibrations of the mate sonic toothbrush are generated in the handpiece of the mate and then transferred to the brush head. This creates a physical abrasion, which cleans your teeth optimally. You only need to apply very slight pressure to the teeth.

How long does the battery last?

The battery is very powerful. It lasts up to 60 days*. If the battery is empty, it can be fully recharged within just two hours. Ideal conditions for vacation or business trips.

*Calculation based on 2x a day a 2 minutes cleaning. At approx. 22 degrees storage temperature and in the pink cleaning program.

Is it possible to replace the battery?

No, unfortunately the battery of your mate cannot be replaced by yourself. For a lifetime of strong battery performance, we recommend the mate Care & Repair subscription .

How do I charge the mate sonic toothbrush?

The sonic toothbrush comes with a charging station with magnetic connector. This means that the mate sonic toothbrush can simply be placed in the charging station. The battery is charged via the magnetic connector.

The charging station is connected to a power outlet. Important: A socket adapter for the USB-C charging cable is not included in the scope of delivery. You can use any conventional adapter that connects USB-C and power outlet. For example, Apple iPhone charging cable adapters.

My sonic toothbrush does not charge. What to do?

You have placed the mate in the charging station and it does not charge?

Of course, there can be several causes for this. One common cause is the position of the sonic toothbrush in the station.

1. Make sure that the toothbrush is positioned completely straight in the station. Then the light of the illuminated ring should also shine.

2. Clean the magnetic charging ring on the underside of your sonic toothbrush and dry it with a towel.

3. Clean the inside of the charging station. The contacts should be free of dirt so that they can transmit the voltage. Please do this carefully - with a handkerchief, for example.

If the toothbrush still does not charge, please contact us at

What is the difference with other sonic toothbrushes?

The mate sonic toothbrush is characterized above all by its slim, minimalist design. This sets it apart visually from conventional sonic toothbrushes.

Secondly, the mate does without plastic for the housing. Instead, aluminum is used. This makes it significantly more valuable and ensures a pleasant feel.

One major advantage of the mate is its outstanding battery life. It can be fully charged in just 2 hours. The battery then lasts up to 60 days! Many other sonic and e-toothbrushes need to be charged for 12 hours or more.

When should I change the brush head?

We recommend changing the brush head every two to three months at the most. This makes sense from a purely hygienic point of view. This way you always brush with a fresh toothbrush.

Brush heads

How often should I replace the exchange head?

We recommend replacing the brush head every three months. The reason: Over time, the bristles wear out and bacteria form in the brush head. This is the case with every toothbrush. You can prevent this by changing the brush head in good time.
