This patient had her teeth several shades whiter than what she started out with. The color speaks for itself.
I bleached one of these young man’s tooth as a test case to see if I could remove brown mottled enamel stains and whiten it. As you can see I was successful on the one tooth I treated.
This patient had a root canal (endo treatment) on his front tooth and it had turned dark. I was able to internally bleach the tooth back to the same shade the adjacent teeth were.
