From doing a little research and asking the same question, YES you can. However, would it be worth it? You can pick up a double pack (two heads, two handles (?), one charger, and a travel case) for around 90 dollars from bj's or sams. With that aside you can do it one of several ways. One would to get a wide screwdriver and basically crack it open, though you might break it. The other would require a dremel and a steady hand. You take the dremel and a 1/8" disc (AND SAFETY GLASSES) and cut carefully around the plastic shell where the two halves are joined. Now that you have it open comes the fun part, more breaking stuff free and soldering. This part is kind of a figure it out because it's not that hard process. But it is very time consuming. Back to my first idea of replacing the whole thing. I do not have a step by step, but would recomend a small jar to keep the parts and probably a digital camera to "remind" you how to put it back together. As for putting it back together you will need some silocone or epoxy, they are both messy. Your call. Fifty bucks a piece, or a whole day and possibly a weekend not to mention frustration. Just try to remember how you had to tell yourself you needed this toothbrush in the first place because it was expensive. And yes I do own one and enjoy it. There are other ideas out there, but......... $50. If this isn't the answer you were looking for than I must apoligize.
