I am going to use Oral-B dental floss.

This round's longevity item is a dental care item.

After reading many people's posts, I found that most people were using dental irrigators, sterilizers, and other devices... and floss.

Among them, many people recommend Oral-B dental floss, so I also bought it.

I didn't use it often because it was a hassle, but reading your posts has inspired me. I set a goal to use it at least once a week.
