Teeth whitening may cause temporary tooth sensitivity or mild gum irritation, which usually subsides within a few days.
The procedure may be less effective for teeth that are purplish-red, gray, or speckled due to antibiotic use.
Whitening treatments do not lighten dental restorations such as fillings, dentures, crowns, or veneers, so these may remain a different shade than your natural teeth after treatment.
