I'm an Invisalign patient, and I find myself using it every time I brush before I put the trays back in. I don't use traditional floss any longer. Even after brushing thoroughly, there are always a few food particles that get flushed out.
I think this waterpik product improves my dental hygiene. Not five stars because the new unit is lighter in weight and makes more noise than the unit it replaced.
Had this for about a month and it works very well. Dentist recommended a Waterpik wp100 series. I was informed that the water pressure could be adjusted and that the unit came with multiply cleaning tips. Another plus. I also like the tank because I don't have to refill it constantly while in use. Had another type of water cleaner but could not adjust the pressure, found it hard to use. This one gets down with getting into hard to reach areas. Fantastic.
