1. Understand dental plaque: the real problem behind 80% of oral health issues

Dental plaque is a biofilm made up of bacteria. When it isn't removed properly, it hardens and becomes tartar.

Consequences:

• persistent bad breath;

• gum inflammation;

• bleeding gums;

• visible yellowing of teeth;

• risk of teeth loosening.

The longer plaque stays, the harder it is to remove.

2. Why a toothbrush alone isn't enough (and why 67% of French people have tartar)

Even with 2 brushings a day, the interdental areas, under the gumline, and molar fissures remain almost impossible to clean properly.
Studies show that a regular toothbrush removes only 60% of plaque, with the remaining areas responsible for buildup that hardens in 48 to 72 hours.
