What is the direct answer?

What does this question mean?

Whitening strips are flexible plastic strips coated with a peroxide gel that oxidises some stain molecules in enamel. They do not change the colour of fillings, crowns, veneers, or other restorations.

What can you do next?

Follow the product directions, keep gel off the gums, and stop if you develop marked pain or persistent irritation. A dentist should check untreated decay, cracks, enamel wear, or gum disease before whitening.

When should you seek dental care?

Seek care before whitening if you have toothache, cavities, exposed roots, cracked enamel, or inflamed gums. Contact a dentist if sensitivity or soft-tissue irritation persists after stopping.

What should you ask the dentist?

Ask which whitening ingredient and concentration are present. Ask whether existing restorations or untreated dental disease could make the result uneven or the treatment uncomfortable.

Frequently asked questions

Can strips whiten fillings?

No. Peroxide changes natural tooth colour, not most restorations.

What if my gums burn?

Remove the strip, rinse, and stop use until a dental professional advises you.
