    A tooth that's darker than its neighbors typically indicates that the pulp tissue within it has undergone some type of degenerative change.

    Here's why the darkening occurs.

    As tissues inside the tooth deteriorate, dark-colored breakdown products are formed.

    [For example, as hemoglobin (a compound found in red blood cells) decomposes, dark iron-based compounds are released.]

    These byproducts can leach into the tooth's hard tissues (dentin and enamel) and cause tooth staining.

    Even after a tooth's root canal treatment has been completed, its staining will remain.

    If the tooth requires a dental crown, then its placement can remedy the color mismatch. If not, then whitening treatments (tooth bleaching) can be performed.
