Tooth Tunes Musical Toothbrush dissection

The Tooth Tunes Musical Toothbrush plays two minute pop song clips to help kids count down an appropriate length of tooth brushing time. Suspecting that this used a transducer to conduct the sound through the bristles and into the jaw (bone conductance) I wanted to both know for sure and see how easily it could be hacked, so I bought one and took it apart. Here are photos of that dissection. The audio IC is potted so I suspect it will be hard to change the sound which is played, but I think the transducer itself could make for a fun little toy. The sound quality is decent when the transducer is held directly against the teeth, the head, or any large, flat surface (eg: workbench).

  1. As my daughter was listening to her Tooth Tunes play “All-Star” by SmashMouth, she swore she heard a little of “Kiss the Girl”. I bet ALL the Tooth Tunes songs are in EVERY Tooth Tunes brush only I’m not clever enough to hack them out. But I bet you are ….

  2. so it potted aye? Well that no good i want to hack one as a little joke among some friends, you know put a new song on it. Any way is the problem lie with it being potted or the format?
