What Kind of Teeth Whitening Can Weaken Tooth Enamel?

Dental whitening products do not damage your enamel.  These products only remove surface stains that are in the microscopic pores of your teeth.  The bleach does not penetrate deeply within the tooth.  This is why intrinsic (deep) stains, such as Tetracycline stains, do not bleach well.  As far as sodas, diet Coke is still acidic and an overabundance of it can damage the enamel of your teeth.  Hope this helps.  

This is a question I get asked frequently.  The professional whitening products do NOT cause damage to the enamel.  The teeth have small holes in them like a sponge.  The whitening products remove small stain and proteins from the surface of the teeth to allow more light to reflect...thus, allowing you to see a brighter tooth!

I have been whitening teeth for many years in my office and have never seen a case where the enamel of the tooth was damaged from the whitening product.  I also see people all the time who have damage on their teeth from drinking soda pop.  Even the sugar free pop, like diet Coke, is very acidic and will erode and eat away the enamel of the teeth.  There can be some temporary sensitivity from whitening, but no permanent damage.  Most people also only need to whiten a few days a year to keep their teeth bright.
