Dentists Clarify Effectiveness of Korean 3-3-3 Brushing Technique
The Korean 3-3-3 brushing technique suggests brushing three times a day, for three minutes each, within three minutes of eating, and changing your toothbrush every three months.
Dentists say this is a helpful guideline but not strictly necessary.
Brushing for three minutes is good, but you should wait a bit after eating acidic foods.
Brushing twice a day for two minutes is usually enough.
Also, flossing, regular dental check-ups, staying hydrated, and cleaning your tongue are important for keeping your mouth healthy.
