Safe teeth whitening at home
At-home whitening should follow dental assessment and product instructions because peroxide, tray fit, and sensitivity affect risk.
The short answer
Peroxide gel can whiten some natural stains but does not whiten fillings, crowns, or veneers in the same way.
How should you use whitening gel safely at home?
Use only a recommended product, keep gel off gums, and follow contact time.
What should you check before whitening your teeth at home?
Ask for advice before whitening with untreated disease, severe sensitivity, or restorations.
When should tooth sensitivity after whitening be assessed?
Ask which stains respond and what to do if sensitivity occurs.
Which stains and restorations should you discuss with your dentist?
