I recommend Oral-B dental floss.

I always make sure to brush my teeth three times after meals.

There are cases where bad breath persists even if you brush your teeth diligently.

In this case, use dental floss to clean every nook and cranny between the teeth

I realized that I need to remove food particles.

Oral-B dental floss has toothpaste ingredients coated directly on the floss itself, so it gives a refreshing feeling.

I think brushing your teeth after removing food particles with dental floss is a really good way to keep your teeth clean.
