Whiterteeth dental
Dental whitening lightens natural tooth colour with peroxide-based treatment selected after checking enamel, gums, decay, and restorations.
The short answer
Dental whitening uses a peroxide-based gel to lighten natural tooth structure after a dentist checks the teeth, gums, existing restorations, and the cause of discolouration. It does not lighten fillings, crowns, veneers, or other artificial materials.
What is the direct answer?
What does this question mean?
Whitening can address stains from foods, drinks, tobacco, or age-related colour changes in enamel and dentine. It cannot repair decay, cracks, gum disease, or uneven surfaces, and sensitivity can depend on enamel condition and the treatment method.
What can you do next?
Begin with an examination and cleaning when indicated, then discuss dentist-supervised trays or an in-clinic procedure. Use the prescribed gel and wear time exactly as directed, and avoid improvised mixtures or products that irritate the gums.
When should you seek dental care?
Seek an examination before whitening for toothache, bleeding gums, cavities, cracks, severe sensitivity, or a single tooth that has darkened. Contact the dentist if gel causes gum burns, persistent pain, or marked sensitivity.
What should you ask the dentist?
Ask what caused the colour change, whether all visible teeth are natural, and which method and gel concentration fit your mouth. Ask how sensitivity will be managed and whether any existing restorations need a separate shade plan.
Frequently asked questions
Can whitening fix yellow fillings?
No. A filling may need polishing, replacement, or shade-matched treatment instead.
Why do teeth feel sensitive afterward?
Whitening can temporarily irritate dentine and the tooth nerve, especially when teeth already have exposed or sensitive areas.
