How do I take care of my teeth?

Hello.

How do you take care of your teeth?

The "Brush 333" rule is to brush your teeth within 3 minutes after each meal, three times a day.

Are everyone keeping it?

I heard that just brushing your teeth isn't enough for good dental care. Using interdental brushes or dental floss is recommended for better oral health.

I'm trying to use it these days, but I wonder if I'm using it incorrectly. I bleed quite often.

It feels refreshing after using it, but I'm worried because it bleeds. How are others using it?
