Mrs. Shin brings her 9-year-old daughter, Sally, in for her examination and prophy appointment at 9 am. She tells you that she is concerned that Sally’s permanent teeth are coming in really yellow and asks if they should be bleached. You explain that it is natural for permanent teeth to appear more yellow due to the differences in deciduous and permanent teeth. Once her permanent teeth have all erupted, they will not appear so yellow since there is no longer a contrast between them and the whiter/blue hue of her primary teeth. The mother admits that the color difference does not bother Sally, but it is something that Mrs. Shin notices.
You discuss the guidelines from EU Directive 2011/84 EU (Cosmetic Products Enforcement Regulations 2013) which only permits individuals 18yrs and over for tooth whitening. If Sally is unhappy with the color of her teeth after her permanent dentition has fully erupted, you can revisit options, which may be very different than what exists today.
