Because your smile is one of the first things that people notice about you, it makes sense to have your teeth, gums, and lips carefully assessed by the dentist. To begin with, tooth-whitening can improve the color of yellowed and stained teeth, and replacement of amalgam (silver) fillings with tooth-colored composite materials can further whiten smiles. If necessary, composite bonding or porcelain veneers can be used to cover damaged teeth, while bridges, crowns, or implants fill in the gaps left by missing teeth. Irregularities in tooth length and shape can be addressed with tooth-contouring procedures so that the smile line formed by the edges of the upper teeth follows the curvature of the lower lip. These changes get noticed!
P.S. Most people recognize a pleasing smile as one in which the two central front teeth have a width-to-length ratio of 4-to-5.
