A fixed prosthetic procedure in which teeth weakened by trauma, extensive decay, or loss of an old filling are functionally rebuilt with porcelain or zirconia-based crowns.
Indication
- Reconstruction of teeth with crown loss or fracture after trauma
- Teeth structurally weakened by extensive decay or loss of an old filling
- Protection of teeth with insufficient remaining tooth structure after root canal treatment
- Cases with functional loss due to tooth wear (attrition, abrasion)
- Color or shape disturbances causing functional problems (e.g., tooth anatomy disrupting occlusion)
- Reinforcement of teeth that will serve as bridge abutments
- Crown design over an implant
Preparation
- Clinical examination, digital or periapical radiography
- Tooth vitality testing; if needed, root canal treatment is planned beforehand
- If gum disease is present, it is treated before the crown
- Assessment of opposing teeth and bite (occlusal analysis)
- Color selection and choice of material (porcelain, zirconia, e.max, etc.)
How it's performed
- Under local anesthesia, the tooth is reduced by the thickness of the crown (preparation)
- An impression of the tooth is taken with silicone or by digital scanning
- A temporary crown is placed until the permanent crown is ready
- The crown prepared in the laboratory is tried in for fit, color, and bite
- Once the fit is confirmed, the crown is bonded to the tooth with a special cement
- The bite is checked one final time and adjusted if needed
Post-procedure
- Hot-cold sensitivity may occur during the first 24-48 hours and is transient
- Periodic radiographic follow-up is recommended for implants and root-canal-treated teeth
- Daily brushing, flossing, and use of interdental brushes for gum health
- Check-up and dental cleaning every 6 months
- A night guard is recommended if bruxism (teeth grinding) is present
Risks
- Sensitivity in the pulp (tooth nerve), or rarely the need for root canal treatment
- Decay beneath the crown (secondary caries) — particularly when hygiene is inadequate
- Fracture or cracking in porcelain crowns (especially in patients with bruxism)
- Visible crown-tooth margin due to gum recession
- Transient temporomandibular joint complaints if the bite is uneven
FAQ
How long does a porcelain crown last?
With proper care and hygiene, the average lifespan is 10-15 years. Bruxism, trauma, and hygiene habits affect this duration. Regular check-up appointments can extend the lifespan.
Is the tooth preparation reversible?
No. Because the tooth structure is permanently reduced, the need for a crown is ongoing. For this reason, less invasive alternatives should also be considered when assessing the indication.
Can I have a crown placed only to make my teeth whiter?
Crowns are not recommended on healthy teeth solely for color. For staining, less invasive options such as tooth whitening or laminate veneers with minimal preparation are evaluated first. The decision is made on the basis of clinical assessment.
Can a tooth with a crown still decay?
The crown itself does not decay, but secondary decay can develop beneath it at the crown-tooth margin if hygiene is inadequate. Regular brushing, flossing, and check-ups reduce this risk.
