What is In-Office Teeth Whitening?

In-office whitening is a supervised treatment intended to lighten natural tooth colour. The clinic first assesses the cause of the colour concern. It may be discussed for suitable natural teeth after examination. Existing restorations and sensitivity need consideration. A consultation decides.

Who it may be for

It may be discussed for suitable natural teeth after examination. Existing restorations and sensitivity need consideration. A consultation decides.

How suitability is assessed

An examination checks for decay, gum problems, sensitivity and the cause of discolouration before bleaching is considered. Whitening acts on natural tooth colour. It cannot correct tooth shape or alignment, and a single dark tooth may need a different assessment.

What happens at the clinic

  1. Assess the colour concern

    The clinic examines the teeth and any existing restorations.

  2. Discuss suitability

    Expected limits and possible sensitivity are explained.

  3. Whiten and review

    The proposed treatment is carried out with follow-up advice.

Options and limitations

Cleaning may address surface deposits, while bonding or veneers change appearance by adding restorative material; they have different preparation and maintenance implications. Whitening responses vary, colour may change again, and crowns, veneers and fillings do not lighten alongside natural teeth.

Care and follow-up

Temporary sensitivity or gum irritation can occur. Follow the individual product and aftercare instructions and contact the dentist if symptoms persist or worsen. Discuss any future whitening before replacing visible restorations so their colour can be considered together.

Questions you may have

Will crowns and veneers whiten too?

Whitening does not change restorative materials in the same way as natural teeth. Their colour needs consideration during planning.

Can whitening cause sensitivity?

Sensitivity can occur. The clinic can discuss your existing sensitivity and how it affects the proposed approach.

Can I choose an exact final shade?

The response varies. The clinic can discuss realistic expectations after examining the teeth.

Is whitening permanent?

No fixed duration can be promised. Natural tooth colour can change again with time and habits; discuss whether further supervised treatment would be appropriate rather than repeatedly using products without review.
