Crown lengthening (AKA: “crown-elongation” or “crown-extension”) is a surgical procedure that is done when the tooth is too short to provide adequate retention for a restoration (usually a crown). When a tooth has a deep cavity, a crown and buildup are usually needed to restore the tooth. If the cavity extends too far below the gums, it becomes impossible to predictably make a crown that will last for any length of time. Performing crown lengthening where indicated improves the prognosis for the tooth. Crown lengthening nearly always involves removing and re-contouring some of the bone around the tooth. This results in more tooth structure above the gums and smooth flowing gum contours. Not every tooth that needs a crown also needs crown lengthening surgery, it is only necessary when a deep cavity or crack is present. This procedure can also be performed on the front teeth to improve esthetics.
