Dental crown lengthening surgery

Teeth are often covered by too much gum tissue, so crown lengthening surgery is an optimal solution to lengthen the crown. So what exactly is this method?


What is crown lengthening surgery?

Crown lengthening surgery is a procedure in which the surgeon removes part of the gum tissue, bone, or removes both gum tissue and bone to reveal longer teeth. This condition is common in patients with gingivitis, most commonly due to the following reasons:

  • Short upper lip
  • Short crown
  • Alveolar bone is overdeveloped
  • Overdeveloped upper lip muscles
  • Complications after orthodontic treatment

After surgery, more exposed gums and roots will give you a confident smile in communication.


Under what circumstances should this method be used?

Crown lengthening surgery is performed when the teeth have the following conditions:

  • Teeth are covered by too much gum tissue.
  • Teeth are too short
  • Teeth that are too short will make your smile less than perfect. However, it is possible to fix this problem. At that time, gum tissue and bone will be adjusted so that the natural roots of the teeth are more exposed, helping to bring harmony to the smile and make the periodontal healthier.

Surgery is performed using one of two techniques:

Surgical technique with Piezo: the tip that affects the tooth root is delicately designed, avoiding damage to the root surface.
Traditional technique: use a drill to drill the bone and shape the cavity from which to adjust the tooth root accordingly.


What are the possible risks and complications?

When surgery to lengthen the crown, not everyone encounters unwanted conditions. However, we need to know the potential risks in advance to be able to make the most accurate decision! Possible risks include:

  • The gum area may bleed for some time after surgery.
  • Infection
  • Some patients experience sensitivity to heat and cold due to exposed root canals, the sensitivity disappears with time or after the crown is placed.
  • Removing bone from a tooth can make it looser. Sometimes, if this tooth is lost, it will make it more difficult to place a dental implant to restore the tooth.


You need to be re-examined when experiencing the following conditions:

  • Gum tissue that bleeds non-stop
  • Painkillers don't work
  • Signs of infection: runny nose, bad breath, fever...
  • Your gum tissue is red, swollen and painful
  • Sutures become loose or fall off
  • Difficulty swallowing
