A waterpik is essential after brushing your teeth.

No matter how thoroughly I brush my teeth, I find that fine debris comes out when I clean every nook and cranny with a Waterpik. I can't use interdental brushes because they constantly make my gums bleed, so I use a Waterpik instead. The Waterpik has various modes, so I usually use the soft mode, and occasionally I use the pulse mode to massage my gums. After using it, my gums feel so refreshed, as if I've replaced them entirely. Since I bought this model a while ago, there are now many Waterpiks available that are cheaper and offer a wider variety. You should consider giving it a try!
