360 Whitening before and after
Professional whitening lightens natural tooth stains, but the before-and-after result depends on tooth colour, restorations, and stain type.
What result can professional whitening give your natural teeth?
Professional whitening lightens natural tooth stains, but the before-and-after result depends on tooth colour, restorations, and stain type.
How does peroxide change the colour of stained teeth?
A whitening treatment uses peroxide to break down coloured molecules in enamel and dentine. It does not change the colour of ceramic, composite, crowns, veneers, or fillings, so those areas can look different after natural teeth lighten.
What should you arrange before comparing whitening results?
Start with an examination, scale and polish when indicated, and a shade record or photographs under consistent lighting. The dentist can identify whether whitening, replacement of a restoration, or treatment of internal discolouration addresses the appearance.
When should tooth problems be checked before whitening?
Seek assessment before whitening if a tooth is painful, cracked, decayed, dark after an injury, or has a leaking restoration. Contact the clinic if treatment causes persistent sensitivity or chemical irritation of the gums.
What should you ask about stains and existing restorations?
Ask what caused the discoloration, which teeth are suitable for whitening, and how existing restorations will be handled. Ask to compare the planned shade with your natural teeth rather than relying on edited photographs.
Frequently asked questions
Will every tooth become the same shade?
Not necessarily. Restorations and different types of internal or surface staining can respond differently.
Why do whitening photos look brighter than real life?
Lighting, camera settings, editing, and dehydration of enamel can alter photographs, so clinical shade assessment is more useful.
