The Most Effective Brushing Technique: The Modified Bass Method

This is the method most widely recommended by dentists.

Step-by-Step

  1. Hold the toothbrush at 45° to the gum margin — the bristles should just enter the gingival crevice
  2. Use small circular or gentle vibratory movements (not horizontal scrubbing)
  3. Spend 10–15 seconds in each area
  4. Work through outer surfacesinner surfaceschewing surfaces in order
  5. For the inner surfaces of the front teeth, hold the brush vertically
  6. Brush the tongue gently too (bacteria accumulate there)
  7. Total time: at least 2 minutes

Common Mistakes

MistakeWhy it is wrongThe correct approach
Brushing too hardGum recession and enamel wearGentle circular movements
Horizontal scrubbingDoes not clean the gum margin45° angle with vibratory motion
Finishing in 30 secondsInadequate cleaningAt least 2 minutes
Brushing only the outer surfacesPlaque builds up on the insideInclude every surface
Using a hard-bristled brushDamages enamel and gumsA soft-bristled toothbrush
Rinsing with lots of water after brushingWashes away the fluorideRinse lightly with a small amount of water

Choosing a Toothbrush

FeatureRecommendation
Bristle stiffnessSoft — medium and hard brushes CAN DAMAGE the gums
Head sizeSmall to medium (reaches the back teeth)
HandleComfortable, non-slip grip
Electric?Oscillating–rotating models (e.g. Oral-B) remove around 21% more plaque in trials
ReplacementEvery 3 months, or sooner when the bristles splay
03

Using Dental Floss

Brushing alone is not enough — a toothbrush cannot reach around 40% of interproximal surfaces. Flossing once a day:

How to Floss

  1. Cut a 40–45 cm length and wind it around your fingers
  2. Gently slide it between the teeth using a sawing motion
  3. Wrap the floss in a C-shape around each tooth and move it up and down
  4. Use a clean section of floss for each contact

Alternatives to Floss

  • Interdental brushes: Ideal for wider gaps between teeth
  • Water flosser (e.g. Waterpik): Effective around bridges and implants
  • Floss picks: Easier than string floss but less effective

Frequently Asked Questions

Common Questions

How many times a day should I brush?
At least twice — in the morning after breakfast and in the evening before bed. You can also brush after lunch, but twice a day is sufficient.
Should I brush immediately after eating?
After acidic foods and drinks (citrus, fizzy drinks) wait 30 minutes — the acid softens the enamel temporarily and brushing straight away can cause erosion. After other meals it is fine to brush immediately.
Is an electric toothbrush better than a manual one?
With the right technique, both are effective. However, oscillating–rotating electric brushes remove around 21% more plaque in clinical studies. For anyone who finds the technique difficult (children, older adults), an electric brush has a clear advantage.
Do I need fluoride in my toothpaste?
Yes. Fluoride strengthens the enamel and reduces the risk of decay by 25–30%. Children should use an age-appropriate amount of fluoride toothpaste.
How often should I floss?
At least once a day, ideally in the evening before brushing. Floss removes plaque and food debris from the surfaces between teeth that a toothbrush cannot reach.
Is tongue cleaning necessary?
Yes. Bacteria on the tongue are the most common cause of bad breath. Clean the tongue once a day with a tongue scraper or the reverse side of your toothbrush.
When should I use mouthwash?
After brushing and flossing, once or twice a day. Fluoride mouthwash helps prevent decay; chlorhexidine mouthwash helps with gingivitis.
When should children start brushing their teeth?
As soon as the first primary tooth erupts (6–8 months) a parent should wipe the teeth. From 2–3 years, move on to brushing with a children's toothpaste. --- Questions about your oral hygiene?
