The short answer
Teeth whitening is chosen by matching a peroxide-based method and its concentration to the cause of discoloration, the condition of the teeth, and the health of the gums.
How do peroxide gels differ from surface polishing?
Whitening gels use peroxide chemistry to oxidise stain molecules within enamel and dentine; surface polishing works differently and does not change the colour of a filling, crown, or veneer. Sensitivity and gum irritation depend on concentration, contact time, fit, exposed dentine, cracks, and existing inflammation.
What should you treat before whitening your teeth?
Have active decay, leaking restorations, and gum disease assessed before whitening. Follow the supplied application time, keep gel off the gums, and avoid unverified mixtures such as acids or harsh abrasives.
When should whitening wait for a dental assessment?
Seek care before whitening if you have toothache, cavities, gum bleeding, recession, cracks, or a single dark tooth after injury.
What should you ask about stains and whitening safety?
Ask what caused the colour change, whether restorations will match afterward, which agent and concentration will be used, and how sensitivity will be managed.
