Teeth whitening lightens discoloration in enamel and dentin using professional gels under a dentist's supervision. It can be done in a single office visit or at home with custom trays.
Performed professionally, it does not harm enamel; temporary sensitivity may occur afterwards. How long results last varies with coffee, tea and smoking habits.
