What is the direct answer?
A whitening kit should be selected after checking the teeth, gums, restorations, peroxide material, and tray fit.
What does this question mean?
Peroxide breaks down stain molecules; sensitivity can involve dentine tubules and gum irritation can follow gel contact or poor tray fit.
What can you do next?
Have decay, cracks, gum inflammation, and restorations checked first; follow directions and stop if pain or irritation develops.
When should you seek dental care?
Seek care for persistent sensitivity, gum burns, uneven colour, or a darkened tooth after injury.
What should you ask the dentist?
Ask which stains can respond, how restorations will look, and what plan is suitable if sensitivity occurs.
