There are a number of methods used for tooth whitening including, most commonly, at home whitening, in house treatments, and internal whitening. The purpose of each, as well as the results, will vary.
Case #1: At Home Whitening
This young lady wished to improve the appearance of her smile, as she felt that her teeth were a bit dark and discoloured. Her teeth were a slightly darker shade, and had some small patches of discolouration on them as well. After a 4 week course of home whitening, her teeth became noticably lighter in shade, and the patches diminished. This simple, safe and conservative treatment created a dazzling new smile for this young lady.
