What type of stains have best prognosis?
Teeth darkened during aging (brown-orange) respond predictably by lightening approximately 2-3 increments on the dental shade guide. Other types of stains (fluorosis, smoker s stain, tetracycline) are also lightened, but results are case dependent. Routine use of home bleaching prior to placing anterior restorations on older patients may be advisable since subsequent bleaching causes mismatch with existing restorations.
