I’m worried that teeth whitening will ruin my teeth.

Dear Dentist
Dear Dentist
My question is regards to whitening � Is Hydrogen Peroxide bad for your teeth or whitening in general does it cause cavities if you used say 30% in house bleaching?
I am confused because it is a weak acid so why do we use it on whitening?
Does a high percent of Hydrogen Peroxide not cause cracks in teeth or make them matte/loose their shine?
How does whitening work? thank you for your time

Hi
Whitening works by penetrating through the slightly porous enamel layer to the more porous dentine. The breaking down of peroxide to water and oxygen radicle is the cause for oxidation and thus bleaching of he substance it is in contact with.
Thirty percent is the limit of bleach concentration that is considered safe for hydrogen peroxide although weaker concentrations will do the job.
The chemical will not cause pkysical damage or cracks, nor does ot cause loss of shine.
Just because it is an acid does not mean it cannot be used it is the ph and concentration that matter. hope this helps
