What is crown lengthening?

Reset Decrease Increase
A cavity may appear below the gum tissue and is often only revealed with x – rays.

It is not possible to restore these cavities since the gums prevent access. A solution for this problem starts with the raising of a flap.

Different instruments, including the dentist’s drill are used to reduce the bone height and this new bone architecture is prepared to support the gums in a lower position at the root of the tooth.

The new bone topography must follow all the previous picks and valleys. The gums are then repositioned on the prepared bone which now supports the gums below the cavity.

The cavity can now be accessed. In this situation, a resin filling is used to restore the cavity.

The reason because this procedure is called crown lengthening is because the crown tends to look longer after the procedure is finished.
