Tooth Structure For Crowns
how much tooth is needed for a crown
Dental crowns require sufficient tooth structure for stability and support. Generally, at least 1–2 mm of healthy tooth must remain after preparation.
Tooth Preparation Guidelines
Dentists typically remove 1–2 mm of enamel from all sides to accommodate the crown. The exact amount depends on the crown material and tooth condition.
- Minimum tooth height: 1–2 mm
- Width reduction: 1–2 mm
- Healthy根基 required
When Is a Crown Possible?
If a tooth is severely damaged, build-up material or a post may be used to provide additional support. Insufficient structure might require alternative treatments.
Consult your dentist for a personalized assessment. Modern crowns are designed to maximize preservation of natural tooth structure.
