What it is
Crown lengthening is a periodontal surgical technique that exposes more healthy tooth structure, reshaping the gum and, if needed, the underlying bone, within periodontics.
When it’s indicated
It’s necessary when a tooth is heavily worn or fractured and there isn’t enough visible structure to fit a crown or prosthesis stably, or when the gum covers too much of the tooth (a “gummy smile”) and a more harmonious result is wanted as part of a dental aesthetics plan.
- A heavily worn or fractured tooth with little visible structure for a crown or veneer
- A gummy smile, when the gum covers too much of the tooth
- Needing more biological space before a prosthetic restoration
What the process looks like
- Aesthetic or functional planning We determine how much gum and bone need reshaping depending on the goal, whether aesthetic or for a future restoration.
- Reshaping surgery We recontour the gum and, if necessary, the underlying bone, under local anaesthesia.
- Healing and restoration Once the area has healed, the prosthetic restoration is carried out, or the aesthetic result is complete.
Frequently asked questions
Is it the same as a gingivectomy?
They're related: a gingivectomy only reshapes the gum, while crown lengthening can also include reshaping the bone when more exposed tooth structure is needed.
How long do I need to wait for the final crown or veneer?
Usually between 6 and 8 weeks, the time needed for the gum to heal and settle into its new position.
Is it only a cosmetic treatment?
Not always. It's often a necessary step so a prosthetic restoration can be fitted correctly and last longer.
