I have a similar situation; a cosmetic i.e. asthetic bonding is broken on the side [because the teeth imploded on each other when I had a ice skating accident injury to the side of the back of the head = momentum, sideways]. So it's invisible to everyone else, and the glue or Poly-[A]crylic-[A]cid is leaking out and gumming up my teeth and getting on my hands, hair and skin and then polymerizing with things like graphene and gluten, making me a walking Christmas Tree antenna.
You could ask them to redo the sealant. My dentist didn't charge anything that time because they knew this was bugging me for so long. That will make it smooth again, but in my case, you can't guarantee that when it's fragmented like Mount Rushmore, it won't get abraded by food more and break down further, becoming rough again. That's what happened 5 days later, but that's because I didn't have a complete restoration, to make the whole surface smooth and resistant to food again.
With my warm-heart and good-luck,
