Your teeth can be whitened in many different ways by a dentist. They are grouped into external techniques and internal techniques.
In external techniques, as the name implies, involves placing the whitening gel on the outer surface of your teeth. However, this method do not work for some types of staining like those caused by metal fillings or condemned blood vessels inside the teeth. External whitening can be done in two ways, namely home tooth whitening and Laser (power) tooth whitening.
