It works!
Is this as good as a  professional cleaning?  Of course not.  Does this remove 100% plaque?  Of course not.  But it does work and removed a lot of the plaque on my teeth.  Due to covid and health issues, I have not been able to get to the dentist, but this really did do a good job of cleaning  my teeth.  Glad I bought it.
