Did you know that around 40% of Polish adults have poor oral hygiene habits, including toothbrushing? [1]. Even people who try to brush their teeth as thoroughly as possible often make technical mistakes - for example, they skip the inner surfaces of their teeth or fail to reach the gumline, where the most bacteria accumulate. That's why dentists around the world recommend the Bass technique - an easy brushing method that effectively reaches these hard-to-reach areas.

What is the Bass technique, and why does it work?
The Bass technique involves gently brushing the gums at a 45-degree angle using small, circular motions. It was developed by dentist Charles Bass in 1954 and focuses on removing plaque from the gumline - where inflammation that can lead to various diseases develops [2].
Unlike traditional toothbrushing, the Bass technique gently massages the gums, improving blood circulation and removing bacteria from the gum pockets. This is where harmful microorganisms that cause periodontitis accumulate. The secret to the Bass technique's effectiveness is that the toothbrush bristle tips reach beneath the gumline, where traditional horizontal movements are not enough.
Studies confirm that the modified Bass technique is more effective at removing plaque than regular brushing [3].

Step 1: Get the right tools
You need a soft-bristled toothbrush or a sonic toothbrush. Which sonic toothbrush work best? Choose a model with a frequency of at least 31,000 vibrations per minute to effectively remove plaque. A toothbrush whose head oscillates 30 degrees in each direction is also a good choice, as it adapts better to the natural shape of your teeth and cleans them more thoroughly.
Step 2: Set the right angle
Hold the toothbrush at a 45-degree angle to the gumline. The bristles should gently enter the gap between the gum and the tooth, without applying pressure.
Step 3: Make massaging movements
Make small circular movements for 10-15 seconds on each tooth surface. Don't drag the toothbrush across your teeth - let it “work” in one spot.
Step 4: Clean your teeth one by one
Divide your mouth into 4 sections and spend 30 seconds on each. Remember to clean the tops of your teeth and their inner surfaces, on the tongue side.

Results of the Bass technique - what can you expect?
After one week of use:
- less gum bleeding,
- fresher breath,
- smoother tooth surfaces.
After one month:
- noticeably healthier gums,
- approximately 40% plaque reduction [4],
- less tooth sensitivity.

Common mistakes with the Bass technique
- too much pressure - the Bass technique requires a gentle touch. Too much pressure can damage the gums and enamel,
- incorrect angle - a 45° angle is essential - a wider angle won't reach the gum pockets, while a narrower one can damage the gums,
- rushing - each tooth surface needs 10-15 seconds. Rushing is the main reason the technique is ineffective.
Sonic vs. rotary toothbrush - which is better for the Bass technique?
Sonic toothbrushis ideal for the Bass technique thanks to its gentle vibrations, which massage the gums without damaging them. Models sonic-rotating combine the benefits of both technologies.
Rotary toothbrush (oscillating-rotating) works a little differently - the brush heads rotate. Although it effectively removes plaque, care is needed around the gums.
Sonic toothbrush specifications for the Bass technique:
- frequency: approx. 31,000 vibrations per minute,
- brush heads: small, with soft bristles,
- modes: gentle on sensitive gums.
Which sonic toothbrush is best for children?Choose a model with a smaller brush head and a frequency of 20,000-25,000 vibrations per minute. Children over 3 years old can safely use a sonic toothbrush under supervision.
