As a rule, even high-quality toothbrushes are not that expensive: if you want, you can always afford the desired purchase.
However, this is only true if we are talking about regular brushes.
Sometimes an oral cleaning accessory can be incredibly expensive.
It is hard to believe, but there are references regarding the accessory for such a high price. The sale was carried out through an auction.
The high price is explained by the fact that the previous owner was a famous cosmonaut.
In this case, we are already talking about an accessory that anyone can buy for themselves. The famous brand Reinast produces an expensive accessory for teeth.
As it turns out, this brush has special bristles, thanks to which it can last for six months. After that, the manufacturer sends a replacement nozzle.
Thanks to this, an expensive brush can last for years.
