Black spot in molar, is it a cavity?

[Himanshu]

While brushing my teeth today, I noticed a dark spot in my left molar along with few other brown stains on teeth. It doesn't hurt but I am concerned whether its a tooth decay or some form of stain. Due to covid I am avoiding going to dentist right now, could someone please advice?

Good day
Difficult to give an opinion without a clinical exam or x-ray. Quite possible that it could be decay. Best to visit your dentist for an evaluation.
