Crown lenghtening is usually performed to improve the appearance of the gums around the teeth. With crown lengthening we can reduce the appearance of a "gummy smile". A "gummy smile" is used to describe a situation where more than 2-3mm of gums is relieved when someone is smiling, resulting in a less esthetically-pleasing smile and wrong teeth proportions.. The procedure involves reshaping or recontouring the gum tissue and some times bone around the tooth in question to create a new gum-to-tooth relationship. Crown lengthening can be performed on a single tooth, many teeth or the entire gum line.
Crown lengthening is often required when your tooth needs a new crown or other restoration and the decay has destroyed the tooth down to the bone area. Crown lengthening allows us to reach the edge of the restoration, ensuring a proper fit to the tooth. It should also provide enough tooth structure so the new restoration will not come loose in the future.
