Get teeth bleached
Professional tooth bleaching uses peroxide-based gel after a dental assessment to lighten natural tooth colour and manage sensitivity risks.
The short answer
Professional tooth bleaching uses peroxide-based gel after a dental assessment to lighten natural tooth colour and manage sensitivity risks. The gel changes internal stain molecules in enamel and dentine; it does not whiten fillings, crowns, or veneers.
What is peroxide-based tooth bleaching?
Bleaching is a chemical whitening treatment, usually based on carbamide peroxide or hydrogen peroxide. A dentist first checks for decay, cracks, leaking restorations, gum inflammation, and the cause of discoloration before choosing the method.
What should you record before starting bleaching?
Have the shade and restorations recorded, then follow the prescribed in-office or custom-tray schedule. Reduce exposure to strongly staining foods and drinks during the treatment period and report sharp sensitivity so the plan can be adjusted.
When should a dentist examine a tooth before bleaching?
Arrange an examination before bleaching if a tooth is painful, darkening alone, fractured, decayed, or sensitive. Contact the practice for persistent severe sensitivity, gum burning, or an uneven result that needs assessment.
Which bleaching method and formulation are suitable?
Ask what caused the discoloration, whether existing restorations will match afterward, and which peroxide formulation and delivery method are proposed. Ask how sensitivity will be managed and when replacement of mismatched restorations would be considered.
Frequently asked questions
Will bleaching whiten a crown?
No. A crown keeps its material colour, so the dentist plans shade matching separately.
Why do teeth feel sensitive after bleaching?
Peroxide can temporarily increase dentine sensitivity, especially where enamel is thin or roots are exposed.
