Teeth Whitening Conditions: Is Whitening Right for You?
Every smile is different. Whether you're concerned about yellow teeth, smoking stains, sensitivity, or an existing dental condition, our guides explain what whitening can and cannot do — so you can make an informed decision.
Not everyone's teeth are the same — and neither are the concerns that bring people to consider whitening. Some patients worry about yellowing from years of coffee drinking, others want to know if whitening is safe after braces or with sensitive teeth, and some need clarity on whether existing dental conditions rule out treatment entirely.
We've created these condition-specific guides to answer the most common questions honestly and clearly. Each page explains what whitening can realistically achieve, any limitations to be aware of, and the steps involved in safe, dentist-supervised treatment.

Learn more →Why a Professional Assessment Matters
Regardless of your concern, the first step is always the same: a professional assessment with a GDC-registered dentist. During your consultation, your dentist will:
- Examine your teeth and gums to confirm suitability for whitening
- Identify the type and cause of any discolouration
- Check for conditions that may need treatment before whitening can begin
- Explain what whitening can realistically achieve for your individual teeth
- Create a personalised treatment plan with the right gel strength and schedule
This honest, no-pressure assessment ensures that you understand your options before committing to any treatment. If whitening is not suitable, your dentist will explain why and discuss alternatives.
