How to Brush Your Teeth Properly: 90% of People Are Doing It Wrong Without Knowing

You brush twice a day but still get cavities? Chances are you're brushing the wrong way. This article breaks down the most common mistakes and how to fix them.

How to Brush Your Teeth Properly: 90% of People Are Doing It Wrong Without Knowing

90% of people brush their teeth wrong – Are you one of them?

Mistake #1: Brushing too hard

Many people believe harder brushing = cleaner teeth. Completely wrong.

Brushing too hard causes:

  • Irreversible enamel wear
  • Permanent gum recession
  • Chronic tooth sensitivity

The right way: Use gentle pressure with small circular motions. Quick test: if your toothbrush bristles are flattened after 1 month, you're brushing too hard.


Mistake #2: Brushing too fast

The average Vietnamese person spends 45 seconds brushing. The time you actually need: 2 minutes.

The right way: Divide your mouth into 4 sections (inner/outer × upper/lower) and spend 30 seconds on each. Use a timer or a 2-minute song to keep track.


Mistake #3: Only brushing the outer surfaces

The inner surfaces of your teeth (the tongue side) are where plaque builds up the most, yet they get the least attention.

The right way: Brush all 3 surfaces: outer → inner → chewing surfaces


Mistake #4: Rinsing right after brushing

The fluoride in toothpaste needs time to absorb into your enamel. Rinsing immediately washes it all away.

The right way: Spit out the toothpaste but don't rinse (or rinse just once, lightly). Wait at least 30 minutes before eating or drinking.


Mistake #5: Skipping dental floss

A toothbrush only cleans about 60% of your tooth surfaces. The remaining 40% (the spaces between teeth) can only be reached with floss.

The right way: Use dental floss or a water flosser once a day, ideally before bed.


Mistake #6: Brushing right after eating

After a meal, acids from food temporarily soften your enamel. Brushing right away can wear it down.

The right way: Wait 30 minutes after eating before you brush. You can rinse with plain water right after your meal.


The proper brushing checklist

  • ✅ Soft-bristled brush with a small head
  • ✅ Fluoride toothpaste
  • ✅ Brush for at least 2 minutes
  • ✅ Hold the brush at a 45° angle to the gumline
  • ✅ Gentle, circular motions
  • ✅ Brush the inner and chewing surfaces too
  • ✅ Don't rinse right after brushing
  • ✅ Floss once a day
  • ✅ Replace your toothbrush every 3 months

No matter how well you brush, you still need a professional scaling every 6 months at a dental clinic to remove the plaque and tartar that can't be cleaned at home.
