What If I Already Have Color-Matched Restorations?
Teeth whitening can only whiten the natural tooth enamel. If you have restorations, Dr. Stark evaluate any old fillings, crowns, etc. for replacement. Replacing restorations will occur post-whitening so that they will match your newly bleached teeth!
