This is great for reaching back teeth or cleaning between any teeth if you have spaces in them. I have not, however found it to be any kind of 'replacement' for actually flossing.

Since my dentist gave me a sample one to try, I have added this to my dental routine, along with regular brushing and flossing and it has been helpful.

So i'm not a huge fan of flossing and bought the Sulcabrush a couple weeks ago. So far so good! its designed so its easy to handle and my teeth and gums feel fresh and clean when i'm done. The bristles are tough and the brush comes to a point so it gets into the groves of your teeth. Its also great to reach behind that last tooth at the back. You get 4 refills, two brushes, one for home use with two ends and one for travel/on the go uses that has one end with a storage compartment. You can also mail in for a free travel pouch.
