What does “Crown lengthening” mean?
Crown lengthening adjusts the position of the gums and, when needed, bone to expose more natural tooth in the mouth. It is considered to obtain tooth structure for restoration or adjust the proportions of teeth and gums.
Why might it be needed for a restoration?
If decay or a fracture extends below the gum, there may be insufficient space to establish a healthy restoration margin. The assessment considers whether exposing the remaining tooth would allow restoration.
Is only gum tissue removed?
The approach depends on the distance between the planned margin and bone and the gum tissue to be retained. Cases suitable for gum removal alone are distinguished from those requiring bone adjustment or another approach.
What is compared before treatment?
The effects on root support, adjacent teeth, and aesthetic areas are assessed. Alternatives such as orthodontic extrusion are compared, and the timing of prosthetic treatment after healing is planned.
Frequently Asked Questions
Does it make the tooth itself longer?
It adjusts surrounding tissues to expose more of the existing tooth; it does not grow new tooth structure.
Is it possible for every short tooth?
Root and bone support and gum shape can impose limitations. The benefit of greater exposure must be weighed against loss of support.
