[How long does a tooth last after a surgical crown lengthening?]
Nederlands Tijdschrift Voor Tandheelkunde
|October 10, 2023
Summary
Surgical crown lengthening can preserve teeth with subgingival pathology, but long-term survival depends on factors like crown-root ratio and patient hygiene. Careful case selection is crucial for successful tooth preservation.
Area of Science:
- Periodontology
- Restorative Dentistry
Background:
- Subgingival pathology presents challenges for tooth preservation.
- Surgical crown lengthening is a common treatment option for these cases.
Approach:
- A literature review was conducted to assess the long-term prognosis of teeth treated with surgical crown lengthening.
- Four clinical studies with a minimum 5-year follow-up were included.
Key Points:
- Tooth survival after surgical crown lengthening is influenced by several factors.
- An unfavorable crown-root ratio negatively impacts prognosis.
- Poor plaque control and difficulty maintaining restoration cleanliness are associated with adverse outcomes.
Conclusions:
- Surgical crown lengthening can be a viable option for tooth preservation when challenging subgingival conditions exist.
- Patient-related factors, including oral hygiene and the restorability of the tooth, are critical for long-term success.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
