Theres a brown spot on my left Molar,in the back.
It doesnt hurt tho,And It doesnt feel weird when I eat or antyhing
its just got a brown spot.
I've tried brushing,and everything
but it wont go away,it just kinda faded.
is it a cavity?

If you can see a spot that doesn't come off, it may be a cavity. They don't hurt initially, only once they've gone through your tooth enamel. Go to your dentist and have it checked out. Stop it before it gets worse.

Only thing, is if you said it faded and went away, it wasn't a cavity. Cavities don't go away on their own.

See your Dentist to find out for sure...Good luck !!
