Yes, whitening strips do damage enamel. Your teeth have three layers — enamel, dentin and connective tissue. The dentin layer has a high protein level, including several collagen proteins. Dentin is critical to supporting and strengthening your enamel.
Teeth whitening is not permanent. While the whitening and shine tend to stay for a period of time, even months, foods and beverages that cause staining can cause the whiteness to fade away.
Enamel doesn't have any living cells and is unable to repair itself if it undergoes damage. In other words, unlike the rest of the human body that can repair itself, once the enamel is gone, it's gone forever.
Tooth enamel does not grow back, but it can be restored to some degree by remineralization. Using mineralized toothpaste and mouthwash can strengthen your remaining enamel as the minerals will be drawn to the weak spots in your teeth and bond with the surface.
