Excellent nozzle, and it cleans the plaque that builds up between teeth. I decided to get it because tartar can build, and while the brush can remove some of it, it does not remove all of it. This type of toothbrush should only be used on teeth that are robust and healthy.
Cons: At first, the gums will bleed, although this is natural and is explicitly mentioned in the directions. After a while, the bleeding will stop.See full review
