Teeth whitening
Professional whitening lightens the natural colour of your teeth, using whitening products prescribed and supervised by your dentist.
What it’s for
Teeth naturally darken over time, and food, drink and smoking can add staining. Whitening can lighten the colour of natural teeth. It does not change the colour of crowns, veneers, fillings or bonding.
In the UK, whitening must be prescribed by a dental professional and is only available to adults aged 18 and over, unless it is needed to treat or prevent disease.
- Before
- Teeth darken naturally with age, and tea, coffee, red wine and smoking can stain them.
- Whitening gel
- Applied to the surface of the teeth, as prescribed by your dentist. It passes through the enamel and breaks down staining in the layer beneath.
- After
- The same tooth, lighter. How much lighter varies from person to person.
Your consultation
Your dentist will check your teeth and gums, look at any existing fillings or crowns that may affect the result, and talk with you about the shade you would like and what is realistic for your teeth.
They will explain exactly how the whitening is carried out, how long it takes and how to look after your teeth during treatment.

Questions
Will whitening change the colour of my fillings or crowns?
No. Whitening only affects natural teeth. If you have visible fillings, crowns or bonding, your dentist will explain how that may affect the overall result.
Is the result permanent?
No. Results fade gradually, more quickly with tea, coffee, red wine and smoking. Your dentist can advise you on how to maintain them.
Will my teeth be sensitive?
Some people notice sensitivity during whitening, which is usually temporary. Tell your dentist if it happens and they will advise you.
