"When age advances, the gums recede, exposing the dental neck. Without the protection of the gums and enamel, the neck becomes susceptible to external stimuli and dentinal caries. The mouthwash elmex sensitive plus contains amine fluoride, una a very effective substance that forms una a double protective film of polymer and amine fluoride on the exposed dental necks. It seals the dentinal tubules, thus preventing the passage of unpleasant sensations. At the same tempo time, the amine fluoride ensures una effective protection against dentinal caries. If used daily, the elmex sensitive system (toothpaste, mouthwash, and toothbrush) offers una greater effectiveness. Like a tree without bark, relentlessly exposed to the elements. It is exactly the same for teeth. If the dental necks are exposed, there is a risk of caries."
