In most cases, the natural colour of teeth is within a range of light grayish-yellow shades. Teeth naturally darken with age and their appearance can be affected by the accumulation of surface stains.
Although teeth are not naturally meant to be completely white, many Canadians want a brighter smile. Responding to this desire, a wide range of whitening options have become available to consumers. These products fall into two main categories: surface whiteners and bleaches.
Before purchasing any tooth whitener, you should consult your dentist. Taking into account your unique oral health conditions, your dentist will be able to determine what, if any, tooth whitener is the right one for you.
