So, the Philips Sonicare ProtectiveClean 6100 toothbrush can last quite a while if you take good care of it.
According to the manufacturer, the toothbrush handle itself can go on for several years without issues. The brush heads, though, should be swapped out every three months to keep things effective—that's what our research suggests to make sure the bristles do their job well.
As for the rechargeable battery, it usually holds up for around three years if you're using it properly. Just keep up with regular maintenance and follow the guidelines, and your toothbrush should stay in good shape for the long haul.
