At home dental bleaching
At-home bleaching uses peroxide gel in a tray or strip to lighten natural teeth after decay, gums, sensitivity, and restorations are checked.
The short answer
Home bleaching lightens some natural teeth with peroxide, but an examination should precede treatment because restorations do not bleach and disease can worsen symptoms.
What is the direct answer?
What does this question mean?
Carbamide peroxide or hydrogen peroxide releases oxygen that reacts with coloured molecules in enamel and dentine. Concentration, contact time, tray fit, and tooth condition affect irritation.
What can you do next?
Have decay, cracks, leaking fillings, gum inflammation, and restorations assessed. Use only the directed amount, keep gel off gums, and stop for significant burning or sensitivity.
When should you seek dental care?
Seek care for severe sensitivity, gum burns, tooth pain, uneven darkening, or a single dark tooth, which may need diagnosis before bleaching.
What should you ask the dentist?
Ask whether the stain is intrinsic or surface-level, which restorations will remain unchanged, and how sensitivity will be managed.
