Was passiert mit der alten Zahnbürste?

Anstatt dein defektes Modell wegzuschmeißen, reparieren wir es dank des modularen Designs der KOA V2 bestmöglich, und bereiten es wie neu auf. Bei einem schwachen Akku, tauschen wir den Akku aus. Das reparierte Modell geht nicht einfach wieder in den Verkauf, sondern wird wiederum für Garantiefälle als Austauschmodell genutzt. Das nennt sich auch Kreislaufwirtschaft.

brush heads

Special features of bamboo attachments?

No, you can use the bamboo attachments like your old ones.

Make sure you clean the brush head regularly and change it every 2 months.

wood taste?

We sand our attachments in a lengthy process so that the surface becomes extra smooth. Due to the after-treatment you can hardly taste any woody taste, and after just a few uses you can hardly feel any difference to conventional brush heads.

Most people even prefer the natural mouthfeel of bamboo attachments compared to plastic attachments.

What do the essays consist of?

The KOA V2 attachments are made of bamboo (neck), castor oil (bristles) and bio-plastic (inner part).

In order to optimally transfer the vibrations to the brush head, the inner part is necessary, which we developed from biodegradable plastic.

Application sonic toothbrush KOA V2

When should you change the brush head?

Dentists recommend changing the brush head every 2-3 months. This applies to our manual toothbrush as well as to the sonic toothbrush.

If you are the owner of the KOA V2 sonic toothbrush, you can easily see when it is time to change the attachment by the green indicator bristles.

Proper use of a sonic toothbrush

The ideal brushing time is two minutes. To do this, divide your rows of teeth into four “jaw quadrants” and brush each part for 30 seconds. It is important to brush both the outer surface, chewing surface (front teeth are excluded here) and the inner surface of the rows of teeth. Good sonic toothbrushes have a 30-second interval timer, which gives you consistent brushing results.

Which toothpaste to use with the sonic toothbrush?

Overpriced toothpastes are often offered for sonic toothbrushes, but you can continue to use your favorite toothpaste as usual.

Nevertheless, it is recommended that it has a low level of abrasion and therefore does not contain any coarse particles.

Sonic toothbrush despite braces?

A sonic toothbrush can also be used by people with braces. In fact, a sonic toothbrush can be very useful for removing plaque and bacteria from the teeth and around the braces, as the high speed of the sonic vibrations allows the brush to reach deep into the spaces between the teeth and the braces.

If you are still unsure, it is best to consult your dentist.
