The current trend in dentistry is leaning towards a blending of preventative and cosmetic care. For example, modern fillings are usually matched to your natural tooth color now, which is technically a cosmetic solution to a traditional issue. However, there are some treatments that are purely cosmetic, such as tooth whitening, smile makeovers, and sometimes braces. With the importance placed on the perfect smile, it is not uncommon for teens and preteens to want these procedures.
