Professional teeth whitening gel pen
A professional whitening gel usually contains peroxide and is selected and applied according to the teeth, gums, staining, and sensitivity present.
How is professional whitening gel chosen for your teeth?
A professional whitening gel usually contains peroxide and is selected and applied according to the teeth, gums, staining, and sensitivity present.
Which dental restorations cannot be whitened by the gel?
The gel does not whiten porcelain, ceramic, composite, metal, crowns, veneers, or fillings. Existing decay, gum recession, cracks, exposed dentin, and enamel defects can increase sensitivity or irritation, so the mouth is examined before treatment.
How is whitening gel applied and monitored in a clinic?
A clinician may clean the teeth, protect the gingiva with a barrier or custom tray, apply the gel for planned intervals, and monitor comfort and shade. Follow instructions, avoid gel contact with gums, and report significant sensitivity or burns.
When should a dark or painful tooth be checked before whitening?
Seek dental care before whitening if one tooth is dark, teeth hurt, gums bleed, or restorations are visible in the smile. Contact the clinic if pain or gum irritation persists after treatment.
What should you ask about peroxide, restorations, and sensitivity?
Which peroxide is being used, how will the gums be protected, will existing restorations match, what causes my staining, and how will sensitivity be managed?
Frequently asked questions
Can a gel pen replace professional whitening?
A pen may deliver a different amount and contact pattern, and it does not replace examination or professional isolation.
Why are my gums white after gel?
Peroxide contact can irritate or temporarily blanch gum tissue; persistent pain or a lesion needs review.
