Correct Brushing Technique: Seven Common Mistakes

Plenty of patients brush regularly and still develop decay and gum problems. The issue is usually not frequency but technique.

1. Horizontal scrubbing

A sawing motion causes gum recession and notching at the tooth neck. Instead, angle the brush at 45 degrees to the gum and use small circular/vibrating strokes (Bass technique).

2. Using a hard brush

Hard bristles do not clean better; they wear enamel and gum. A soft brush with correct technique is always sufficient.

3. Pressing too hard

Bristles splay under pressure and clean less. Holding the brush like a pencil naturally reduces force.

4. Brushing too briefly

Average brushing lasts 45 seconds; two minutes is required. Dividing the mouth into four zones of 30 seconds works well.

5. Forgetting the tongue

The tongue surface holds the highest concentration of odour-causing bacteria. Clean gently from back to front.

6. Skipping floss

A brush reaches only about 60% of tooth surfaces. Between-tooth areas need floss or interdental brushes — where much decay begins.

7. Brushing straight after something acidic

Enamel softens temporarily after orange juice, cola or vinegar. Brushing immediately accelerates wear; wait 30 minutes and rinse with water meanwhile.

Quick checklist

  • Soft brush, 45° angle, small strokes
  • Twice a day, two minutes each
  • Floss once a day
  • Fluoride toothpaste
  • Replace the brush every three months
