What is the direct answer?

What does this question mean?

Carbamide peroxide breaks down into hydrogen peroxide and urea, allowing peroxide to diffuse into tooth staining. A custom tray holds gel against the enamel and should keep it away from the gums.

What can you do next?

Have the tray fit checked, place only the instructed amount in each tooth compartment, and wipe away gel that reaches the gumline. Follow the product schedule and stop if marked sensitivity, gum soreness, or tissue whitening develops.

When should you seek dental care?

Seek dental advice before use if you have untreated decay, cracked teeth, gum disease, enamel defects, or strong sensitivity. Contact the dental team if pain persists after removing the tray or if gel contacts the eye or is swallowed in excess.

What should you ask the dentist?

Ask whether the concentration and tray fit suit your enamel, restorations, and gum condition. Ask how long each application should remain in place and how existing crowns or fillings will appear beside whitened enamel.

Frequently asked questions

Can whitening gel whiten fillings?

No, peroxide changes natural tooth colour but does not change the shade of fillings, crowns, or veneers.

What if the gums turn white?

Remove the tray and rinse; contact the dental team if soreness or colour change continues.
