Surgical Crown Lengthening

For a broken down tooth to be rebuilt with a crown, there needs to be a minimum two millimeters of tooth for the crown to grip onto.  This is called the “Ferrule Effect.”  If this is not available, we can often create it by repositioning the gum further along the root to expose more tooth.

If there is excess gum, sometimes it can be trimmed with a laser, otherwise the gum may need to be prized back slightly  and 1-3 millimetres of bone height is removed.  The procedure is similar to having a large filling done with the gum usually a bit tender for a few days later.  The crown will now have a high chance of success.

It is still far less trauma than extracting the whole tooth and later doing expensive and invasive implant surgery to replace it.
