Is there a difference in the effect of whitening strips on natural teeth, crowns and fillings?

Whitening strips or any whitening agent will not change the shade of crowns, veneers, or fillings. They only work on enamel.

Stay away from the professional teeth whitening procedures and from the whitening at home kits. They are using extremely toxic chemicals that can cause IRREVERSIBLE DAMAGE TO TOOTH ENAMEL and premature tooth decay.

Check out this site: http://www.naturalwhiteteeth.net/ - It's about how you can whiten your teeth 100% naturally. Same results but 100% safe and 1000 times cheaper.

Yes ... the stains on your natural teeth are usually shallow and the bleaching agent can whiten them easily ... crowns are dyed to match your existing teeth and any pigmentation is through the material which is then sealed, a superficial bleaching agent is not likely to do much to it to keep up with the effect on the rest of your teeth ...

The only thing you can whiten are natural teeth. So b4 you do any restorative work. Bleach first then restore (crowns, fillings).

Your natural teeth are the only thing that will bleach. Crowns and fillings do not bleach.

Yes, you should see a dentist because the whitening strips may cause discoloration to your crowns, depending on the materials. You want to make sure the shade matches.

sincerely the one that is born with a good calcium in the teeth single to cepillar itself with a good dental cream. the others are life in my country to do that here is expensive and expensive
