Did you know that about 40% of adult Poles have improper oral hygiene habits, including tooth brushing? [1]. Even people who try to brush their teeth as well as possible often make technical mistakes – for example, they skip the inner surfaces of the teeth or don’t reach the gum line, where the most bacteria accumulate. That’s why dentists worldwide recommend the Bass method – an easy brushing technique that effectively reaches these hard-to-access areas.

What is the Bass method and why does it work?
The Bass method involves gently brushing the gums at a 45-degree angle with small, circular motions. It was created by dentist Charles Bass in 1954; it focuses on removing plaque from the gum line – the area where inflammation leading to various diseases begins [2].
Unlike traditional tooth brushing, the Bass method gently massages the gums, improving their blood flow and removing bacteria from gum pockets. This is where harmful microorganisms that cause periodontitis accumulate. The secret of the Bass method’s effectiveness lies in the brush bristle tips reaching under the gum line, where traditional horizontal movements are insufficient.
Research confirms that the modified Bass method is more effective at removing dental plaque than regular brushing [3].
How to brush your teeth using the Bass method – step-by-step instructions
Step 1: Prepare the right tools
You need a brush with soft bristles or a sonic toothbrush. Which sonic toothbrush What works best? Choose a model with a frequency of at least 31,000 vibrations per minute – this will ensure effective plaque removal. A brush with a head that oscillates 30 degrees in each direction also works well, as it better adapts to the natural shape of the teeth and allows for more thorough cleaning.
Step 2: Set the correct angle
Place the brush at a 45-degree angle to the gum line. The bristles should gently enter the gap between the gum and the tooth, but without pressing.
Step 3: Make massaging movements
Make small, circular motions for 10-15 seconds on each tooth surface. Don’t drag the brush – let it “work” in one spot.
Step 4: Brush teeth in order
Divide your mouth into 4 parts and spend 30 seconds on each. Remember to also clean the upper part of the teeth and their inner side facing the tongue.

Effects of the Bass method – what to expect?
After one week of use:
- reduced gum bleeding,
- fresher breath,
- smoother tooth surfaces.
After one month:
- visible improvement in gum condition,
- plaque reduction by about 40% [4],
- reduced tooth sensitivity.

Common mistakes with the Bass method
- too much pressure – the Bass method requires gentleness. Too much pressure can damage gums and enamel,
- incorrect angle – a 45° angle is key – a larger angle won’t reach gum pockets, a smaller one may damage the gums,
- rushing – each tooth surface needs 10-15 seconds. Rushing is the main cause of the method’s ineffectiveness.
Sonic toothbrush vs rotary – which is better for the Bass method?
Sonic toothbrush perfectly suited for the Bass method thanks to gentle vibrations that massage the gums without damaging them. Models sonic-rotary combine the benefits of both technologies.
Rotary toothbrush (oscillating-rotating) works a bit differently – the brush heads perform rotational movements. Although it effectively removes plaque, it requires caution with the gums.
Parameters of a sonic toothbrush for the Bass method:
- frequency: approx. 31,000 vibrations per minute,
- brush heads: small, with soft bristles,
- modes: gentle for sensitive gums.
Which sonic toothbrush is best for children? Choose a model with a smaller 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.
