Less painful: According to people who have worn both metal and ceramic braces, ceramic braces are less painful on your gums and cheeks because the ceramic is not as harsh. Hard to notice: One of the things that make people avoid getting braces even when they need them is the fact that they are visible and can be embarrassing, especially for adults. The brackets used for ceramic braces can be color-matched to your natural teeth, making them difficult to notice at a distance. http://www.dentalbrace.net/ortho-brackets/ceramic-bracket/
