This water flosser does an amazing job if used as directed, and removes particles that my normal flossing doesn't get. I use the finer tip for a more focused cleaning and i'm very happy. A couple things to consider are the batteries that come with the unit might be weak like mine were (I replaced with rechargeable) and the tank gets empty fairly quickly when used at the higher pressure. Also you have to be careful with new batteries and the higher pressure because it's so powerful it can make your gums bleed a little and if you move off a tooth it's kinda painful if the stream is on your tongue etc. I have excellent oral health so this is another tool to keep my teeth happy.

I love this thing but unfortunately water is its enemy and it rusts out and the batteries don't work y'all need to figure that out it would make everybody's teeth a lot happier
