You may already be familiar with some of the basic approaches to whitening your teeth - using over-the-counter products or professional services from your dentist (in-office treatments or custom-fitted trays for at-home use). However, what many people fail to understand is that the results aren't going to be the same for everyone - even if the dentist is the same, even if the whitening product being used is the same.
Many people might assume that bleaching teeth is simply a matter of applying repetitive or strong-enough whitening agents to the teeth. That is simply not the case. When you whiten teeth, only the outer shell of the tooth - the enamel - is affected. The enamel is a translucent layer. That means it's not solid and it's not clear. Light is somewhat scattered as it passes through the enamel, but the color of the underlying tooth remains visible to some degree. That's one very important reason why the tooth whitening process and the results you can expect aren't the same from one person to the next. The color of the core of the teeth can vary substantially from one person to the next. The thickness of the teeth and the enamel, along with other factors, can also influence the outcome. How can I tell what color my teeth are? Unfortunately, you really need a trained eye to do that. Dentists, especially those who are reputable cosmetic dentists, are well versed in "shade management" of your teeth. Even when you see the components of their shade management system, you would be unlikely to determine which of the colors is closest to your own color - that's where the well-trained eye becomes important. Understanding what shade your teeth actually are has an influence on many aspects of cosmetic dentistry - not just tooth whitening - so experience in shade management is important. How does the dentist tell which shade my teeth are? In cosmetic dentistry, shade management continues to get more sophisticated, with more systems continually emerging. We'll provide a brief explanation of how the "classic" system (from Vita) might differ from most people's assumptions. The basis of the classic system is a set of 16 ceramic teeth in different shades. Instead of being the simple light to dark scale that you might imagine, it is considerably more complex. An untrained eye might even assume that some of the samples are the same color. In the classic system, there are four different categories of teeth (A, B, C, D), and four variations within each category (A1, A2, A3, A4, etc.)
