Flash white strips
Whitening strips can lighten natural tooth enamel when their peroxide gel contacts the tooth for the instructed time, but they do not change fillings, crow
The short answer
Whitening strips can lighten natural tooth enamel when their peroxide gel contacts the tooth for the instructed time, but they do not change fillings, crowns, or veneers. The strips are flexible plastic carriers coated with a gel containing a peroxide compound. The peroxide enters the enamel and oxidizes colored molecules, while poor fit or prolonged contact can irritate the gums or trigger tooth sensitivity.

Do not stack whitening products or use strips over untreated decay, cracked teeth, or inflamed gums.
What can you do next?
Check the ingredient and concentration, follow the package wear time, and keep the gel on the tooth rather than the gum. Do not stack whitening products or use strips over untreated decay, cracked teeth, or inflamed gums. Stop and arrange dental care if pain is severe or persists after stopping, if the gum turns white and remains sore, or if a tooth has a cavity, crack, swelling, or marked sensitivity. A dentist can examine the enamel and existing restorations before whitening.
When should you seek dental care?
Stop and arrange dental care if pain is severe or persists after stopping, if the gum turns white and remains sore, or if a tooth has a cavity, crack, swelling, or marked sensitivity. A dentist can examine the enamel and existing restorations before whitening. Ask whether the discoloration is on the surface or within the tooth, whether any cavities or gum inflammation need treatment first, and which product and wear schedule fit your restorations and sensitivity history.

Frequently asked questions
Can strips whiten a filling?
No. They can lighten surrounding natural enamel, but a filling keeps its original shade.
Why do my teeth hurt after strips?
Peroxide can temporarily increase sensitivity by moving through enamel and dentine toward the pulp. Stop use and seek advice if it is strong or does not settle.
