Power whitening
Power whitening uses professionally applied peroxide gel, with controlled timing and soft-tissue protection, to lighten natural teeth.
The short answer
Power whitening uses a professionally applied peroxide gel, sometimes activated by a dental light, to lighten natural tooth structure under controlled conditions.
What is the direct answer?
What does this question mean?
During power whitening, the dental team records the starting shade, protects the gums and soft tissues, applies a peroxide-based gel to the visible natural teeth, and follows a timed application protocol. A light may be used, but the gel’s peroxide chemistry performs the whitening.
What can you do next?
Crowns, fillings, veneers, and dentures do not bleach like natural enamel, so their color may not change. Sensitivity can occur because peroxide temporarily moves through enamel and dentin toward the pulp.
When should you seek dental care?
Have the teeth and gums examined first and treat decay, leaking restorations, or gum inflammation before whitening. Follow the clinic’s aftercare instructions, use a sensitive-teeth toothpaste if advised, and avoid concentrated home chemicals.
What should you ask the dentist?
Ask for an examination if sensitivity is severe or persistent, the gum becomes painful or pale, or the result is uneven. A single dark tooth needs assessment before cosmetic whitening.
Frequently asked questions
Can home care replace an examination?
Home care may ease symptoms or reduce risk, but it cannot diagnose or repair a dental cause that needs treatment.
