How often do I need to get a scaling? 😆😆

Many people are always concerned about dental care and bad breath removal.
I also tend to try to brush my teeth frequently and thoroughly.
They told me that getting scaling done too often wears down your teeth, so they advised against doing it too frequently—maybe about once a year?
Actually, that sound is a bit scary too, haha, so that's another reason I don't answer often.
I've only been receiving it like this, but even though I use the dedicated toothpaste marketed as bad breath removal toothpaste and brush my teeth diligently

Lately, when I look at it, I keep seeing plaque buildup and bad breath, so I wonder if that’s right.

I realized it has been almost a year since I last got a scaling.

I'm curious, so I'd like to ask a question!
How often do you usually get your teeth cleaned? :)
