It might be a stain but you'll need a local dentist to take a look.

The brown spot could be from drinking coffee or tea, or a small cavity. Since the caps are old there could be some decay developing underneath them. Have your dentist check and x-ray the area.

Could be a spot where the cap has been worn through, a stain on the cap, or a cavity along the margin of the cap, or other causes. This is an educational site. We don't have the ability to examine you and provide a diagnosis. For that you will have to see your Dentist.
