A Dark Tooth After an Old Injury Should Be Checked Before Whitening
A single tooth that has changed color after an injury needs assessment before cosmetic whitening. The change may involve the inside of the tooth rather than ordinary surface stain. Even an injury that happened years ago belongs in the history.
Tell the dentist what you remember
Mention sports impacts, falls, previous tenderness, and any past treatment to that tooth. The dentist may assess responses, supporting tissues, and appropriate images. Lack of current pain does not establish that the pulp inside the tooth is healthy.
Choose treatment after diagnosis
Whitening products designed for the whole smile may not address the underlying concern or match that tooth to its neighbors. Depending on the findings, the discussion may involve monitoring, endodontic treatment, or cosmetic options. Ask which problem each proposed step addresses. Avoid repeatedly applying stronger products to the dark tooth while postponing evaluation. Understanding why the tooth changed is the first decision; deciding how to improve its appearance comes after the health assessment.
