Have you ever noticed one tooth that looks darker than the rest?
A single dark tooth is not always a whitening issue. In some cases, the color change comes from inside the tooth rather than surface staining.
Common reasons may include:
🦷 Previous trauma or an old injury
🧠 Changes to the nerve inside the tooth
🎨 Internal discoloration
🔧 Older dental restorations that no longer match the surrounding teeth
That is why whitening will not always correct a darker tooth. The right treatment depends on what is causing the color change in the first place.
A dental exam can help determine whether the tooth is healthy, whether the nerve has been affected, and which cosmetic or restorative options may create the most natural result.
At Dr. Fred Blum & Associates, we look beyond a tooth's appearance to understand why it has changed and what treatment makes sense for your smile.
If one tooth has gradually become darker, or suddenly looks different from the others, schedule an evaluation today.
