What is the KAI rule?

Brushing your teeth  has to be learned and practiced regularly. The parents play a major role in this: as role models and as a supervisory authority, parents can create the conditions for their children to have healthy teeth. It is important to  always follow the same system and follow the same sequence when caring for your teeth – the so-called KAI rule   is the easiest for children  : Chewing surfaces,  outer surfaces,  inner surfaces

How does it work?

  • Chewing surfaces:  First, the child brushes back and forth on the chewing surfaces. It is best to start on the right side: first at the bottom, then at the top. Then comes the left side: first at the bottom, then at the top. Brushing back and forth is allowed here, so that the deep grooves of the molars are also cleaned.
  • Outer surfaces:  The child “paints” circles with the brush on the outer surfaces of the closed rows of teeth: On the right side from the very back to the front and on the left side too. Then the incisors are cleaned as well.
  • Inner surfaces:  Finally, all inner surfaces come on top and bottom. You start again at the back and from red to white, that means from the gum to the tooth. The inner surfaces are “swept out” with small circles or with rotary movements like with a hand brush.

What else is important

Children up to the age of six should use a fluoride-containing toothpaste (maximum fluoride content of 500 ppm). A pea-sized amount is enough for brushing your teeth. A fluoride-containing toothpaste for adults (fluoride content 1,000 ppm – 1,500 ppm) may only be used by children at school age.

Conclusion

It takes a certain amount of time for children to master brushing their teeth perfectly. Children up to the age of six are not yet cleaning professionals – until then, the parents are challenged. The parents must regularly check the cleaning success and clean if necessary. A task that may be tiresome at times, but contributes significantly to the development of healthy children’s teeth.
