A standard dental crown procedure typically requires two visits over two to three weeks. During the first visit, your dentist examines the tooth, numbs the area with local anesthesia, removes any decay, shapes the tooth to fit the crown, takes impressions, and places a temporary crown. During the second visit, the temporary crown comes off, the permanent crown is checked for fit and color, and it is cemented permanently in place. The entire process is routine, well-established, and designed to restore a damaged tooth’s strength, shape, and function with minimal discomfort. This article walks through every step of the crown placement process so you know exactly what to expect.
What Is a Dental Crown Procedure?
A dental crown procedure is a two-appointment process in which your dentist prepares a damaged tooth, creates a custom-fitted cap, and bonds that cap permanently over the tooth to restore its full strength and appearance. The crown covers the entire visible portion of the tooth above the gum line, replacing lost structure and protecting what remains from further damage.
Dentists recommend dental crowns for teeth that are cracked, badly decayed, weakened after root canal treatment, or worn down from grinding. A crown also anchors a dental bridge, covers a dental implant, or corrects a severely discolored tooth. According to the National Dental Practice-Based Research Network, 94% of dentists surveyed recommended crowns for posterior teeth following root canal treatment, making it one of the most commonly performed restorative procedures in dentistry.
The procedure itself has been refined over decades. Modern materials and digital technology have made crown placement faster, more precise, and more comfortable than ever before. Understanding what happens at each stage removes the uncertainty and helps you feel prepared.
What Types of Dental Crowns Are Available?
The types of dental crowns available include porcelain (all-ceramic), porcelain-fused-to-metal (PFM), zirconia, gold and metal alloy, and resin. Each material offers a different balance of strength, appearance, and longevity. Porcelain crowns match natural tooth color most closely and work best for front teeth. Zirconia delivers a flexural strength of 900 to 1,200 megapascals (MPa), according to data published in the Journal of Dental Research, making it the strongest metal-free option available for back teeth. Gold crowns show a 96% survival rate at 10 years, per clinical data reviewed in the Journal of Prosthetic Dentistry, making them the most durable option overall. Your dentist recommends the material based on which tooth needs the crown, how much force that tooth absorbs, and your cosmetic preferences.
What Happens During the First Crown Appointment?
The first crown appointment is the longer of the two visits, typically lasting 60 to 90 minutes. This is where the tooth is evaluated, prepared, and fitted with a temporary crown. Every step in this appointment builds toward creating a precise foundation for the permanent restoration.
- Examination and X-rays: Your dentist examines the tooth visually and takes X-ray images of the tooth and surrounding bone. X-rays reveal the root structure, the extent of any decay, and whether the bone supporting the tooth is healthy. This information determines whether the tooth can support a crown or whether additional treatment, like root canal therapy, is needed first.
- Local anesthesia: The dentist applies local anesthesia to numb the tooth and the surrounding gum tissue completely. You will feel pressure during the procedure but not pain. The numbing typically lasts one to three hours after the injection, depending on the type and amount of anesthetic used.
- Tooth preparation and shaping: The dentist removes any decayed or damaged portions of the tooth, then reshapes the remaining structure into a tapered form that the crown will fit over. This reshaping removes approximately 1 to 2 millimeters of enamel around the entire circumference and from the top of the tooth. The goal is to create a smooth, even foundation that allows the crown to seat securely without altering your bite. If the tooth has lost too much structure from decay or fracture, the dentist builds it up with a composite filling material before shaping, creating a stronger core for the crown to grip.
- Impressions: The dentist takes a precise mold of the prepared tooth and the teeth around it. Traditional impressions use a putty-like material that captures the exact dimensions of the tooth in a physical mold. Many offices now use digital intraoral scanners that create a three-dimensional digital image of the tooth instead. A study published in Cureus (2024) found that CAD/CAM-fabricated zirconia crowns produced a marginal fit of 0.0172 millimeters, significantly tighter than PFM crowns at 0.0375 millimeters, demonstrating the precision digital impression technology achieves. The impressions or digital scans are sent to a dental laboratory where a technician fabricates the permanent crown.
- Temporary crown placement: A temporary crown made of resin or acrylic is placed over the prepared tooth and attached with temporary cement. The temporary crown protects the exposed tooth from sensitivity, bacteria, and shifting while the permanent crown is being fabricated at the lab. Temporary cement is intentionally weaker than permanent cement so the temporary crown can be removed easily at the next visit.
By the end of this appointment, the prepared tooth is protected and the dental lab has everything it needs to build the permanent crown. The lab process typically takes two to three weeks.
How Should You Prepare for a Dental Crown Procedure?
You should prepare for a dental crown procedure by scheduling enough time for the appointment, arranging transportation if you prefer not to drive while numb, and eating a meal beforehand since the anesthesia will make eating difficult for a few hours after. Let your dentist know about any medications you take, any allergies you have, and any history of reactions to local anesthesia. If you feel anxious about dental work, mention that too. We work with patients at every comfort level and can adjust the approach to keep you at ease throughout the process. Keeping up with preventive care like regular cleanings before the procedure also gives the dentist a clearer picture of your oral health going in.
What Happens Between the Two Appointments?
Between the two crown appointments, the dental laboratory fabricates the permanent crown using the impressions or digital scans from the first visit. A lab technician pours the physical impression into a plaster model or loads the digital scan into design software to map the exact shape of the crown. The technician selects the material your dentist specified, matches the shade to your surrounding teeth, and sculpts the crown to fit your bite precisely. The finished crown is inspected for accuracy, then shipped back to the dental office. This fabrication process takes two to three weeks in most cases.
During this waiting period, the temporary crown handles daily chewing and protects the prepared tooth. The temporary crown is not as strong or as precisely fitted as the permanent one, so taking extra care during this window matters.
How to Care for a Temporary Crown
Caring for a temporary crown requires gentler habits than you use with your natural teeth. Temporary cement holds the crown in place firmly enough for normal function but not strongly enough to withstand aggressive chewing or sticky foods. Avoid chewing gum, caramel, taffy, or any sticky candy that could pull the temporary crown off the tooth. Avoid chewing ice, hard nuts, or raw carrots on the side of the mouth where the temporary crown sits.
Brush the area gently with a soft-bristled toothbrush. When flossing around the temporary crown, slide the floss out from the side of the tooth rather than snapping it upward, which can catch the edge of the crown and dislodge it. If the temporary crown does come off, save it and call your dentist right away. The prepared tooth underneath is exposed and vulnerable without its protective cover. Your dentist can recement the temporary crown the same day in most cases. If the tooth is causing significant pain with the temporary crown missing, seek
