Minerals, protein and enzymes make up the remaining 0.6 per cent of the saliva. They provide a wide range of protective and repair functions.
The pellicle, which is deposited on teeth, gums and oral mucosa after brushing, is composed of the proteins, glycoproteins, lipids and enzymes in the saliva and is largely bacteria-free. This pellicle provides important protection: it ensures moisture to protect teeth against abrasion and, above all, it acts as a sort of customs post, controlling which substances are allowed to pass through to the dental enamel.
Unfortunately, bacterial coatings also form on the pellicle over time, in other words plaque or biofilm. This is why regular oral care is important - every 24 hours at the latest, the teeth and interdental spaces should be cleaned carefully and yet painstakingly accurately to avoid caries, gum inflammation, periodontitis and tooth loss. By doing so, your teeth will be very well protected thanks to the pellicle.
