In-surgery teeth whitening
In-surgery whitening is carried out at the practice. Your dentist first checks your teeth and gums and talks through the result you can reasonably expect.

Before
Tell the dentist about sensitivity and any fillings, crowns or other restorations you are concerned about.
During
Ask which whitening option applies, what the dentist expects for your teeth and how to manage sensitivity.
After
You may have temporary sensitivity or gum irritation. Ask what to do if you notice either, and how to maintain the shade afterwards.
FAQs
Can I have whitening without a dental assessment?
Your dentist needs to check whether whitening is suitable and discuss any dental work or symptoms that could affect the plan.
Will existing dental work change colour?
Crowns, fillings, veneers and bridges keep their colour. Discuss how they would look alongside the shade you want.

What happens at the practice
The team protects the gums and applies the gel to your teeth. Ask what the appointment includes and whether home trays or later reviews would be part of your plan.
In-surgery whitening means the dental team applies the whitening treatment at the practice.
Before whitening
Your dental team checks your teeth and gums first. Whitening lightens natural teeth. Crowns, veneers, dentures and tooth-coloured fillings can stay a different shade, so discuss existing dental work before starting.
During the appointment
The dental team protects your gums and applies the whitening gel to the teeth. Ask how long the appointment will take, what result is realistic and how this compares with supervised home whitening.
Sensitivity and results
Whitening can cause temporary tooth sensitivity or gum irritation. Results and how long they last vary. Tell the dental team if discomfort continues.
Ask the practice who would carry out the assessment and provide the in-surgery treatment.
