What Is the 3-3-3 Rule for Brushing Teeth? The Korean Secret to Perfect Oral Care

What Is the 3-3-3 Rule?

The 3-3-3 rule is an easy routine for brushing teeth that originated in Korea. It is straightforward to recall and follow. Dr Sonakshi Sachdeva Babbar, Dental Surgeon, Smiline Dental Clinic, Delhi, explains, "The 3-3-3 rule implies that you brush your teeth three times a day, for three minutes at a time, and wait for at least three minutes after consuming food before you brush."

Let's dissect the rule:

• Brush three times daily: In the morning, after lunch, and before going to bed.
• Brush for three minutes each time: Longer than most people brush, but cleaning all areas of your mouth.
• Wait for three minutes after eating before brushing: This allows your saliva to neutralise food acids, which assists in protecting your enamel.

Why Is the 3-3-3 Rule Important?

Dr Sonakshi says, “Many people brush too quickly or not often enough. The 3-3-3 rule makes sure you clean your teeth well and at the right times. This helps remove food particles, reduce plaque, and keep your gums healthy.” 

Brushing three times a day ensures that you don't allow bacteria to form in your mouth. Brushing for three minutes ensures that you cover all teeth and all surfaces. Waiting three minutes after meals allows your teeth time to heal from food acids, so you don't wear away your enamel.

How to Practice the 3-3-3 Rule

• Have a soft-bristled toothbrush and a pea-sized amount of toothpaste.
• Set a three-minute timer to ensure that you brush long enough.
• Brush softly in a circular motion for all teeth, gums, and the tongue.
• Don't rinse with water immediately after brushing, but allow the toothpaste to remain on your teeth for a couple of minutes.
• Don't forget to change your toothbrush every three months.

What Does Science Say?

A study published in the International Journal of Dental Hygiene concluded that brushing for two to three minutes eliminates more plaque and gum issues more effectively than brushing for a shorter duration. The researchers further added that brushing after meals, but not directly, protects tooth enamel from acid erosion.

Additional Healthy Teeth Tips

• Daily flossing loosens food between your teeth.
• Restrict sweet foods and beverages.
• See your dentist regularly for examinations and cleanings.
• Consume a lot of water to aid in the removal of food and bacteria.

Conclusion

The Korean 3-3-3 rule is an easy and efficient method to keep your teeth clean and healthy. Brushing three times a day for three minutes at a time and waiting three minutes between meals can have a dramatic effect. Give this routine a try and watch your smile brighten up and improve.
