Advantages of Clear Braces
Clear ceramic braces are a type of braces popular in patients looking for more discreet orthodontics as they are less visible than traditional metal braces. Clear braces are smaller and smooth, thus more comfortable than metal braces. The clear braces blend into the color of the tooth making them much less noticeable and almost invisible from a distance.
Ceramic braces are made of a clear ceramic composite that does not stain upon eating or drinking your favorite foods. In addition, these clear ceramic braces help align teeth in a shorter period of time than metal braces. With regular visits and proper care, ceramic braces can help you straighten your teeth and obtain that beautiful smile in less time and fewer visits!
