Waterpik usage is essential

I make sure to use my Waterpik, an essential item, after brushing my teeth!! If you use the Waterpik to finish, you can tell that even if you brushed properly, you didn't actually clean your teeth thoroughly.

This is because various types of tartar and foreign substances come out.

It thoroughly cleans every nook and cranny that a toothbrush can't reach, so I highly recommend giving it a try.
