No!: Teeth bleaching may leave your teeth sensitive temporarily, but will not weaken or damage them as long as you follow directions of products, or of your dentist!

No: Dental crowns are made of porcelain and are not an organic material so the whitening gels have no effect on crowns.

No: The crown will not be affected. But the whitening agent will weaken actual teeth and some glue property used for adhesion if you use the whitening agent the wrong way and not follow your dentist's instruction. Please ask your dentist for advise.

Ask your dentist!: It is right to consider the impact any cosmetic treatment will have on existing restorations. Teeth whitening, in particular, can affect the appearance of a dental crown, but not in the way many people think. Before treating you, your dentist may recommend that you replace an existing crown to match the new, brighter color of your smile.

No: Professional dental bleaching will not change the color of existing composites or crowns. If you are interested in bleaching, a treatment plan is advised prior to restoring your teeth to have optimal shade match.
