Crown Lengthening Surgery: What It Involves and Who It May Help

If your dentist or periodontist has mentioned crown lengthening surgery, you're probably wondering exactly what it involves and whether it applies to you. Crown lengthening is a periodontal procedure that reshapes gum tissue, and in some cases a small amount of underlying bone, to expose more of the natural tooth. It is used both to support restorative work such as crowns or fillings, and to address gum lines that sit unevenly across the front teeth. Suitability depends on your individual gum and bone anatomy, and is only confirmed following a clinical assessment.

What is crown lengthening surgery?

Crown lengthening surgery involves adjusting the gum tissue around one or more teeth to expose more of the tooth structure underneath. This can mean lifting the gum line alone, or in some cases removing a small amount of bone as well, depending on how much of the tooth needs to be revealed and why.

Why would someone need crown lengthening?

There are two main reasons this procedure comes up. The first is restorative: if a tooth has broken down below the gum line, or a crown or filling needs more tooth structure to attach to properly, crown lengthening can expose enough healthy tooth for that restoration to be placed securely. The second is aesthetic evenness: where gum tissue sits unevenly or covers more of the tooth than is proportionate, reshaping the gum line can create a more balanced and natural appearance.

What does the procedure involve?

Crown lengthening is a surgical procedure performed under local anaesthetic. The gum tissue is carefully reshaped around the affected tooth or teeth, and where needed, a small amount of bone is adjusted to support the new gum position. Healing time and aftercare will be discussed as part of your consultation, as this varies depending on how many teeth are involved and the extent of reshaping required.

Is crown lengthening right for everyone?

Not necessarily. Suitability is determined following a clinical assessment, and not all patients are suitable for all treatments. Your gum health, bone levels, and the specific reason crown lengthening is being considered all factor into whether it is an appropriate option in your situation.

Frequently asked questions

Does crown lengthening hurt?
The procedure is performed under local anaesthetic. Your periodontist will discuss what to expect and how to manage recovery as part of your consultation.

How long does crown lengthening take to heal?
Healing timeframes vary from person to person and depend on how much gum and bone tissue is involved. This will be discussed at your consultation.

Can crown lengthening be done on more than one tooth?
Yes, it can be performed on a single tooth or across multiple teeth, depending on what your assessment identifies as appropriate.

Is crown lengthening the same as gum grafting?
No. Gum grafting adds tissue to cover areas of gum recession, while crown lengthening removes or reshapes tissue to expose more of the tooth. They address different concerns.
