I was a long time someone who has laughed at electronic toothbrushes - true to the motto that users would be lazy to move the toothbrush. Until the day when I went to the dentist and the new doctor at once "deep cleaning grooves" from unilateral brushing + diagnosed too much pressure with a normal toothbrush. This day I have been looking for alternative and am eventually landed at Philips Sonicare. At first it is a bit unusual due to the high speed vibration. But you get used to in 2-3Wochen it - then it no longer interferes. The teeth are much cleaner than with a normal toothbrush. One can thus also clean hard to reach corners easily. The battery life is also great. My plaster marks have not deteriorated and gum quality has improved. Tartar has become an alien concept for me since the changeover.
Dar product is definitely recommend !!!
A hint yet: Who wants to have a consistently good cleaning result should renew the brushes according to the manufacturer's specifications on a regular basis! Please do not wait until the bristles are frayed or broken visually - then the cleaning result is (as with a normal toothbrush) not so good.
