For the ancient Egyptians, it was a mixture of wine vinegar and pumice. The Romans are said to have used ground seashells and, in the Middle Ages, people used beech ash and cloves.
Nowadays the contents of toothpastes are far removed from such naturalness and purity. Standard toothpaste usually contain chemical softening agents, synthetic preservatives, artificial flavourings – and in particular, aggressive detergents and an excess of essential oils, real menthol-freshness boosters. Frequently to the detriment of the oral mucosa.
Firstly, a toothpaste boosts mechanical cleaning with a toothbrush. Secondly, it gives a feeling of freshness, which is why toothpastes often have essential oils such as menthol added to freshen the breath.
For the cleaning effect, most toothpastes have cleaning substances added as foaming agents (tensides, detergents). These pack the water-insoluble parts of the plaque in so-called vesicles and transport them away with the toothbrush when teeth are cleaned.
SLS (Sodium Lauryl Sulphate) is normally used as a foaming agent. SLS is created from the treatment of fatty alcohols with sulphuric acid. Although this detergent has a high degree of cleaning power, it does have considerable – scientifically proven – health risks.
SLS irritates both the skin and the oral mucosa, causes white blood cells to die off, leading to bleeding gums, abrasion of the mucosa and promotes the formation of mouth ulcers.
In contrast to most of the usual toothpastes, CURAPROX has introduced Enzycal, which does not contain any SLS. Enzycal protects the oral mucosa from irritation and markedly reduces the risk of mouth ulcers.
Enzycal simultaneously stabilises and strengthens the antibacterial and remineralising functions of the saliva with natural enzymes – without any need for extra exogenous, synthetically produced ingredients.
Moreover, enzycal toothpaste only contains a minimum amount of menthol: essential oils such as this additionally irritate the oral mucosa if used excessively.
What does a toothpaste need to do? Whether it's helping to clean, protect against caries or freshen the breath – it should not be harmful in any way.
