Crown Lengthening

Crown lengthening is a procedure that may be required to prepare a tooth for a crown if there is insufficient hard surface to attach it. Crowns work by capping a broken or decayed tooth with a thin layer of porcelain or ceramic to mimic the appearance of a real tooth.

In cases where tooth decay, wear and tear, or cracks prevent a crown from attaching, dentists may perform a crown lengthening to access more of the hard surface. This involves reducing gum and bone tissue at the base of the tooth to expose more of the tooth over the gumline, allowing for the crown to fit on top.

Until you are ready for your procedure, your dentist will likely place a temporary crown to protect the tooth in the meantime. Based on the results of your X-rays, the dentist will then determine the extent of crown lengthening needed to receive a permanent crown. Local anesthesia and, in some cases, full-body sedation may be warranted to ensure the procedure goes smoothly.

While crown lengthening is a common procedure, some patients experience bleeding and tooth sensitivity afterward. Full recovery from crown lengthening is around three months, during which time dentists recommend OTC painkillers, ice packs, and careful brushing. Patients should avoid hot foods for the day after their crown lengthening procedure and leave the dressings in their mouth for 1-2 weeks until the dentist can re-evaluate the site.

Crown lengthening may also be used in cases where excess gum tissue affects the patient’s smile, making it “gummy.” Speak with your provider to learn whether this procedure can help restore the function or appearance of your smile.
