Whitening basics
Surface stains or internal discolouration: why the difference matters
A darker-looking tooth is a description, not a diagnosis. Understanding where the colour comes from is a useful first step before choosing a cosmetic treatment.

There can be more than one cause
Staining may sit on a tooth’s surface or relate to changes within it. Previous injury, dental treatment and other factors can affect appearance. A dental practitioner is best placed to assess the cause and whether whitening is likely to help.
Describe the change clearly
Note whether the colour affects one tooth or several, when you first noticed it and whether it has changed recently. Think about any past injury or dental work. This simple timeline is more useful at an appointment than trying to label the problem yourself.
Do not diagnose from a photograph
Bathroom lighting, reflections and phone processing can change how a tooth looks. A photograph can help you explain what you noticed, but it cannot establish the cause. Avoid choosing a package solely because an online before-and-after image looks similar.
Match the next step to the concern
For an unexplained colour change, arrange a dental assessment before cosmetic whitening. For questions about an already assessed smile, bring that information to your consultation. Our first-visit guide explains how to prepare for that conversation.
