What is the direct answer?

A dentist bleaching kit normally contains peroxide gel and a tray or other delivery system designed for controlled contact with natural teeth.

What does this question mean?

The gel may contain carbamide peroxide or hydrogen peroxide; the tray holds it against the tooth surfaces while limiting contact with the lips and gingiva.

What can you do next?

The dentist checks restorations and gum health, records the starting shade, makes or selects a tray, explains gel volume and wear time, and reviews sensitivity or gum irritation.

When should you seek dental care?

Store the gel as directed, keep it away from children, do not fill the tray excessively, and stop use if burning or significant pain occurs.

What should you ask the dentist?

Ask what peroxide concentration is supplied, whether the kit is for day or night wear, how restorations will look, and how to manage sensitivity.

Frequently asked questions

Can I use a bleaching kit on a crown?

The crown itself does not change colour with peroxide, so the dentist should plan the shade of natural teeth and restorations together.

Why do my gums turn white with gel?

Gel touching the gum can irritate the surface and make it look pale temporarily; remove the excess and contact the treating clinician if it persists or hurts.
