Hydrogen peroxide teeth whitening at home
Hydrogen peroxide whitens natural teeth by oxidising stains, but home use should follow a labelled dental product rather than improvised solutions.
The short answer
Hydrogen peroxide whitens natural teeth by oxidising stain molecules, but home use should follow a labelled dental product rather than improvised solutions.
What is the direct answer?
What does this question mean?
Peroxide can pass through enamel and dentine and alter stain molecules. Gums, restorations, and exposed roots may respond differently.
What can you do next?
Use clear instructions, keep gel off the gums, and stop for burning or marked sensitivity. Do not mix household peroxide with acids or other chemicals.
When should you seek dental care?
Obtain an examination if teeth hurt, gums bleed, or one tooth is dark. Severe irritation or facial swelling needs prompt care.
What should you ask the dentist?
Ask what is causing the symptom, which examination or imaging is needed, and which treatment options address that cause.
