Sonic toothbrush in shared use? Based on personal experience, not a good idea

[Redaktion]

No, I'm not talking about the social consequences. Our electric sonic toothbrush simply died after about 18 months. The replacement quit even sooner. Both units ended up with the exact same issue, which likely has to do with the fact that my partner and I share one toothbrush body—though of course not the brush heads.

My wife and I have been sharing a toothbrush for over 5 years this way. From the Oral-B brand actually, so I would dare say that it's a problem with the model bc ours was around 80 euros at the time of purchase so definitely not an expensive model or anything.

We even swap brush heads more since we brush in the morning and in the evening so in total that's 4 swaps a day for 5 years = well over 6000 swaps without ANY issue. The only thing that's wrong with the toothbrush since about a month or two is that the softer plastic grip is starting to get worn out and "peel off"...

It isn't enough that brush heads are a business of their own like printer inkjet carthridges, they want to make sure everybody in the household buys an expensive brush for individual use - making them die early on purpose isn't enough!
