- Preparing a Tooth for a Crown or Bridge:
If a tooth is severely decayed or broken below the gum line, there may not be enough tooth structure above the gums to attach a crown or bridge securely. In this case, crown lengthening can be performed to expose more of the tooth so that a crown can be placed successfully.
- Gummy Smile (Excessive Gingival Display):
Some people have a "gummy smile" where too much of the gum tissue is visible when they smile. Crown lengthening can help by removing excess gum tissue to reveal more of the tooth, leading to a more balanced smile.
In cases of severe gum disease (periodontal disease), the gums may recede, causing the tooth to appear "short" or uneven. Crown lengthening can help reshape the gums and remove diseased tissue to improve gum health and appearance.
- To Correct an Uneven Gum Line:
If the gum line is uneven, crown lengthening can be used to create a more symmetrical and aesthetically pleasing gum line, especially in the upper teeth.

Accessing Hidden Tooth Structure:
If there is a tooth beneath the gum that is decayed or damaged, crown lengthening can expose enough of the tooth to allow for better restorative work.
