Cleaning first
Surface staining may improve with cleaning before cosmetic treatment is considered.
Yellow or stained teeth
Tooth colour concerns may come from surface stain, enamel colour, ageing, diet, old dental work or internal tooth changes.

Why do my teeth look yellow or stained?
Colour concerns can come from surface stain, natural tooth shade, enamel changes, old fillings, wear, diet or a single tooth changing internally. The right option depends on the cause.
What you may be worried about
- Whitening may not work evenly.
- Old fillings or crowns may not change colour.
- A dark single tooth may mean an old injury or nerve change.
Possible causes
- Surface stains from food, drink or smoking.
- Natural enamel colour or age-related change.
- Old restorations, cracks or tooth wear.
- Internal changes in one tooth after trauma or previous treatment.
When to treat this as urgent
Urgency level: routine
- One tooth has changed colour after trauma or pain.
- Colour change is linked with swelling, discomfort or a bad taste.
Options that may be considered
Whitening discussion
Whitening may suit some colour concerns, but it does not change fillings, crowns or veneers.
Restorative options
Bonding, replacement fillings or veneers may be discussed only when whitening or cleaning will not address the concern.
What we would consider before recommending treatment
- Whether colour is external stain, natural shade or internal change.
- Existing fillings, crowns or veneers.
- Tooth sensitivity, gum health and expectations.
If it were our own teeth
If it were our own smile, we would want the least invasive option that predictably addresses the actual cause of the colour concern.
A sensible next step
Book a consultation if you want to understand whether cleaning, whitening, restoration or monitoring makes sense.
Choosing the next step
Use the emergency pathway only when the problem may need urgent review.
For routine, planned, or unclear but non-urgent concerns, book a normal appointment. For swelling, trauma, severe pain, bleeding, or a broken tooth that cannot wait, use the emergency assessment instead.
Common questions
Will whitening fix all stained teeth?
No. Whitening changes natural tooth shade but does not whiten fillings, crowns or veneers.
Is one dark tooth different from general yellowing?
Yes. A single dark tooth may need assessment for previous trauma, nerve change or old treatment.
