There can be a wide variety of reasons that you may not be happy with your smile, often related to the appearance of your teeth. This could be that they’re too small, chipped, crooked, yellow or have gaps between them. Another common concern occurs outside the teeth. If you feel like you show too much gum when you smile, chances are you may actually have a condition known as Gummy Smile. This can occur for a number of reasons, and can also be treated in several ways, both temporarily and permanently.
