Professional teeth whitening: a patient guide
How professional teeth whitening works, what results to expect, sensitivity, and why it should be provided by a dental professional in the UK.
How whitening works
Professional whitening uses a peroxide gel that lightens the natural colour of your teeth from within. It is commonly provided with custom-made trays that fit your teeth precisely, worn at home under your dentist’s guidance.
Why see a dentist
In the UK, tooth whitening is a form of dentistry and should only be carried out by a registered dental professional. A check-up first makes sure your teeth and gums are healthy and that whitening is right for you.
What results to expect
Results vary from person to person. Whitening does not change the colour of existing crowns, veneers or fillings, so your dentist will explain how any of these may affect your overall result.
Sensitivity
Some people notice temporary sensitivity during treatment. This usually settles, and your dentist can adjust how you use the gel or recommend products to help.
Keeping your smile bright
Limiting tea, coffee, red wine and smoking helps results last. Occasional top-ups with your trays can maintain your shade, as advised by your dentist.
