Good afternoon!
At my daughter 1,5. On the bottom forward teeth there was something grey-black. I to her began to clean a teeth. Black began to decrease.
What is it and whether correctly I do or make?

If black became will decrease, most likely it is scurf. In any case you correctly do or make, that clean a tooth to a daughter.
