Black stain
Black stain (in technical terms melanodontics ) is a discoloration of the teeth caused by chromogenic bacteria . It usually occurs in deciduous teeth , and occasionally after changing teeth up to around 15 years of age.
Symptoms
Dark-colored residues form on the teeth, which run as dots or narrow lines in a garland shape, especially at the edge to the gums. From a medical point of view, Black Stain is harmless because the plaque does not damage teeth or gums.
distribution
Depending on the examination, about 2.4–21% of children are affected by black stain. Since it is triggered by bacteria, it can be transmitted through the exchange of saliva.
treatment
The discoloration cannot be influenced by normal tooth brushing. Removal is possible through professional teeth cleaning. However, the discoloration reappears after a few weeks. The discoloration usually disappears on its own with puberty.
