probably is not a dr question, but.... i would guess
You need to go to dentist
Hello dear, welcome to Ask a doctor service.
I read your query and here is my advice.
Taking count that all pieces were part of the same tooth I think that problem is with that tooth, probably it is broken.
I don't think this is related to general health issue and you shouldn't be concerned about it.
You need to visit a dentist.
Hope I have answered the question.
Let me know if I can assist you further.
