I recommend dental floss.

I always use dental floss, so I recommend both cost-effective and expensive but good quality options.

Number 1 is the No Brand sponge dental floss, and it offers good value for money.

Number 2 is Dr. Tung's dental floss; it costs 6,000 won per pack, and this one is really good.

They remove all the tartar from every nook and cranny, wow 👍

I usually use No Brand floss lightly, and I use Dr. Tung's floss about two days a week. I make sure to use it even on days I eat meat.
