Crown lengthening is often required when your tooth needs a new crown or other restoration, but due to the position of, for example, decay or a fracture, the edge of the new restoration would be deep below the gum tissue and not accessible to your restoring dentist. Without the crown lengthening procedure in these cases, the surrounding tissues will be chronically inflamed due to the improper spacing between the base of the restoration and the bone.
A temporary crown may be placed prior to crown lengthening by your restorative dentist. During a crown lengthening procedure, excess gum and bone tissue are reshaped to expose more of your natural teeth, which will create a new gum-to-tooth relationship that significantly enhances your periodontal health. Most crown lengthening procedures are very straightforward and there is little or no post-operative discomfort. Sutures and dressing (a protective bandage) are removed after 1-2 weeks.
The restorative dentist will wait approximately 4-6 weeks following crown lengthening before taking final impressions for your final crown. This ensures that the gum, which shrinks slightly as it re-attaches to the tooth during healing, is in its final position.
Whether you have crown lengthening to improve function or esthetics, the benefits will include both a beautiful new smile and improved periodontal health your keys to smiling, eating and speaking with comfort and confidence.
