Pro whitening
Professional tooth whitening uses a controlled peroxide gel after checking enamel, gums, sensitivity, and restorations.
The short answer
Professional tooth whitening is a dentist-guided bleaching treatment that uses peroxide gel to lighten eligible natural teeth after an oral examination.

What is the direct answer?
What does this question mean?
Peroxide breaks down stain molecules within enamel and dentine. It does not recolour porcelain, composite resin, crowns, or fillings, and the outcome differs when discolouration comes from trauma, medication, fluorosis, or enamel defects.
What can you do next?
The clinical process usually includes an examination, cleaning if deposits are present, shade documentation, gum protection, gel placement, and post-treatment instructions. Tell the dentist about sensitivity, pregnancy, decay, gum recession, and existing restorations.
When should you seek dental care?
Seek dental care before whitening if teeth hurt, gums bleed, a tooth has darkened, or you have untreated decay. Contact the clinic if pain persists after treatment or if gel has caused a significant gum burn.
What should you ask the dentist?
Ask whether the colour change is external or internal, whether restorations will match afterward, and whether custom trays or in-clinic treatment fit your needs. Ask how sensitivity will be managed and when a review is needed.
Frequently asked questions
Does professional whitening change crowns?
No. A crown may need replacement later if its shade no longer matches whitened natural teeth.
What if I already have sensitive teeth?
The dentist can identify the cause and adjust the method, timing, or desensitising plan before bleaching.
