Me too, had to wait until the 1960's.

The marketing push was really effective, even on black & white TV.

The originals were so powerful that it would rarely leave anything more than floss would leave behind.

I can only imagine the water jet on new units over the decades got so much weaker maybe because somebody did some accidental eye damage or something.

What I like to do once a week is to use it with hot water, not too hot but about like hot coffee or tea which I do not drink.

I believe there are many types of germs that are highly adapted to thrive at your normal body temperature, and do not survive at temperatures too many degrees away from that.

This seems really good for the gums too not just between the teeth, and the modern offerings basically massage the gums when you pound them with the water jet, the old units would have been too painful for that.

Also on a deep minor toothache just getting started, which feels like it is way down between the root & bone, I have sprayed the tooth directly long enough to heat up the whole tooth which seems to work
