Is black groove cavities?

What causes black grooves?

Black stains on the sealant that cannot be cleaned with regular brushing may be just stains embedded in the grooves or cavities. Black stains that are cavities will look solid black, thick, soft, gray or black shadows may be visible around them, and may also be accompanied by tooth sensitivity or toothache.
so If anyone notices black grooves or stains that cannot be cleaned by themselves. It is recommended to consult a dentist to get a diagnosis and find the most suitable treatment for you.
