Getting a dental crown typically takes two appointments spread over two to three weeks. During the first visit, your dentist reshapes the tooth and fits a temporary crown. At the second visit, the permanent crown is cemented into place. Some offices now offer same-day crowns that compress the entire process into a single appointment.
The First Appointment: Preparing the Tooth
Your dentist starts by numbing the area with a local anesthetic, most commonly lidocaine. The injection targets the specific nerve branches that supply sensation to that tooth and the surrounding gum tissue. Within a few minutes, the entire area goes numb, and you won’t feel pain during the procedure. You’ll still sense pressure and vibration, but that’s normal.
Once you’re numb, the dentist uses a drill to remove a layer of enamel from the outer surface of your tooth. This trimming creates the space your crown needs to fit over the tooth without bulging out or interfering with your bite. The tooth ends up looking like a smaller, rounded-down version of itself. If the tooth is badly broken or decayed, your dentist may do the opposite in some areas, building up missing structure with a filling material so the crown has something solid to grip onto.
Taking an Impression
After shaping, your dentist needs an exact copy of the prepared tooth and the teeth around it. There are two ways this happens. The traditional method uses a tray filled with a thick, putty-like material that you bite into for a couple of minutes. Once it sets, it captures a detailed mold that gets sent to a dental lab, where technicians pour plaster into it to create a stone model of your teeth. The crown is then designed and built from that model.
The newer approach uses a digital intraoral scanner, a wand-like camera that takes rapid images of your teeth and stitches them together into a 3D model on a computer screen. A full-arch scan takes about two minutes. The digital file can be sent electronically to the lab or, in offices with milling equipment, used to manufacture the crown on-site. Both methods produce accurate results, though each has small tradeoffs. Traditional impressions can distort slightly as the material shrinks or expands. Digital scans accumulate tiny alignment errors as images are stitched together, which can be slightly larger for teeth farther from where the scan started.
Wearing the Temporary Crown
Before you leave the first appointment, your dentist places a temporary crown over the prepared tooth. These are usually made from acrylic or composite resin, shaped right in the office using the impressions taken earlier. Temporary crowns serve several important purposes: they protect the exposed tooth from bacteria and sensitivity, keep neighboring teeth from shifting into the gap, and let you chew and smile normally while you wait.
You’ll typically wear the temporary for two to three weeks, sometimes longer if the lab needs extra time. During this period, avoid sticky foods like caramel or taffy that could pull the temporary off, and try to chew on the opposite side when possible. If it does come loose, contact your dentist to have it re-cemented. Leaving the tooth uncovered risks shifting that would prevent the permanent crown from fitting correctly.
The Second Appointment: Placing the Permanent Crown
When the lab sends the finished crown back, you’ll return for a shorter visit. Your dentist removes the temporary crown, cleans any residual cement off the tooth, and tries in the new one. They’ll check three things carefully: how it fits against the prepared tooth, how it contacts the neighboring teeth, and how it lines up with your bite when you close down. Color is also evaluated to make sure it blends with your natural teeth. If anything is off, the crown can be adjusted or sent back to the lab.
Once everything looks right, the crown is permanently bonded using dental cement. The two most common types work differently. One is a glass-based cement that forms a chemical bond directly with the minerals in your tooth structure. The other is a resin cement that creates a strong mechanical grip by interlocking with the microscopic structure of your tooth at a molecular level. Your dentist chooses based on the crown material and the condition of the underlying tooth. After the cement sets, any excess is cleaned away, your bite is checked one final time, and you’re done.
Same-Day Crowns
Some dental offices use chairside milling systems that let them design and manufacture a crown during a single visit. After preparing the tooth, the dentist takes a digital scan, then uses software to design the crown on-screen, adjusting the shape, the way it contacts neighboring teeth, and how it meets your bite. That design is sent to a small milling machine in the office, which carves the crown from a solid block of ceramic.
After milling, the crown goes through a finishing phase of coloring and glazing. For certain ceramic materials, this involves placing the crown in a small oven for about 15 minutes to reach its final strength and shade. The entire process, from scan to cemented crown, takes a few hours rather than weeks. You skip the temporary crown entirely and leave with the final restoration in place. Not every tooth or situation is a candidate for same-day crowns, but when they’re an option, the convenience of a single visit is a significant advantage.
How Long a Crown Lasts
A well-made crown on a healthy tooth can last a long time. A large clinical study tracking crowns over 11 years found an average annual failure rate of just 2.1%, meaning the vast majority of crowns were still functioning well after a decade. The most common crown material in the study was porcelain fused to metal, which remains widely used alongside newer all-ceramic options.
The biggest factor affecting how long your crown lasts is the health of the tooth underneath. Teeth that have had root canals before being crowned fail at a notably higher rate than teeth with living nerves. Molars take more chewing force and tend to see more wear over time. Your age matters too, with older patients facing slightly higher failure rates, likely because of changes in the underlying tooth and gum tissue. Regular dental checkups help catch problems like cement washout or decay at the crown margin before they become serious.
What Recovery Feels Like
After the first appointment, some soreness around the gum line is normal as the anesthesia wears off. The prepared tooth may feel sensitive to hot and cold temperatures for a few days, especially if the nerve is still alive inside it. This usually fades on its own. After the second appointment, when the permanent crown is placed, you might notice your bite feels slightly different for a day or two as you adjust. If the crown feels high when you bite down and doesn’t settle within a couple of days, call your dentist. A quick adjustment to the biting surface is simple and common.
Most people return to eating normally within a day of getting the permanent crown. The tooth may remain mildly sensitive to temperature for a few weeks, but persistent or worsening pain is worth getting checked, as it could indicate the nerve inside the tooth is inflamed.
