Check suitability first
Teeth and gums should be assessed before whitening. Discuss sensitivity, decay, pregnancy or breastfeeding, and any existing restorations. Crowns, dentures and other artificial teeth do not whiten like natural teeth.
What are the treatment options?
Dentist-supervised options may involve fitted trays used at home or treatment in a dental surgery. Ask which method is appropriate, how to use it and when to return for review. Do not increase gel strength or wear time yourself.
Results and possible side effects
The result varies with the starting shade and cause of discolouration; whitening is not permanent. Temporary tooth sensitivity or gum irritation can occur. Tell the dentist if symptoms are troublesome.
Set a clear goal
Explain which teeth or colour changes concern you. Ask whether cleaning should come first, how existing restorations might look afterwards and what the quoted fee includes. Avoid judging your expected result against edited photographs.
Common questions
Will whitening change the colour of a crown?
No. A crown will not lighten in the same way as natural teeth, so discuss colour matching before treatment.
Can a particular shade be guaranteed?
No individual shade or lasting result should be assumed before assessment. Ask what is realistic for your teeth.
