Also worth noting that if you floss properly (maybe also use interdental sticks) the descaling routine becomes a lot more comfortable. For this reason alone it's worth doing.
Flossing was a painful, bloody mess for me the first week or so I did it. Then it felt great, then I ran out of the floss sticks (like a disposable razor, but with floss instead of a blade) and haven't done it since. Such is life.
I found this to be the same with a water pick. At first my gums bled and hurt, but after a few weeks I could turn the power to max and it feels like an awesome massage on my gums. I used to get some food stuck between my teeth, but now almost never do which I presume is due to much healthier gums.
