Braun Oral-B electric toothbrushes are great for keeping your teeth clean, but what happens if you can't pull the head off to replace it? The head on one of ours simply refused to budge, until we pulled it so hard that the head itself came apart - revealing the springs and pins of its inner workings.
We were initially a bit confused by this; maybe the toothbrush heads were different to the usual sort. The toothbrush head, pictured here after removal, had nothing in it but a bit of grime from years of use. And yes, it had been a couple of years, and we had changed the head once at most.
A phone call to the Braun service centre quickly put matters straight. We had indeed pulled the toothbrush head apart, and the mechanism part had clearly fused itself to the metal shaft that sticks out of the toothbrush body. The technician said that we should replace the head every few months (which we knew, but didn't stick to), but also recommended that we remove the head after every use to keep it properly clean. She said that the cement-like gunk that toothpaste creates can easily stick the parts together. Indeed! Well, we were told to try soaking the toothbrush in mildly soapy boiling water for a bit, then to try pulling the head innards off.
After a bit of soaking in soapy boiling water, we grabbed the head with pliers and pulled - and it came off! We were then able to slot a new, standard head on, and all was finally well.
Of course, we could have avoided all this palaver if we'd read the instructions more carefully! They state quite clearly, "After use, rinse the brush head for several seconds under running water with the handle switched on. Then switch off the handle and remove the brush head. Rinse both parts separately under running water and wipe them dry."
