Waterpik WP-70K recommendation

I have genetically weak teeth and used to have bleeding gums, but it has improved a lot since I started using a Waterpik.

It also has a gum massage effect.

It cleans thoroughly even the places brushing can't reach, so I feel uncomfortable if I don't use it for even a day.

It's good, except for the sound being a bit loud.

It rarely breaks down and is sturdy. I highly recommend it.
