Getting a temporary crown placed typically takes about 30 to 60 minutes as part of your first crown preparation appointment. The temporary itself is not the main event. It’s a protective placeholder your dentist makes chairside after reshaping your tooth, and you’ll wear it for 2 to 3 weeks while a dental lab fabricates your permanent crown.
What Happens During the Appointment
The appointment where you receive a temporary crown is really the crown preparation appointment. Your dentist numbs the area with a local anesthetic, then reshapes the tooth by filing it down on all sides so there’s enough room for a permanent crown to fit over it. The edges are smoothed and rounded to create a stable base. After shaping, your dentist takes an impression or digital scan of the prepared tooth, which gets sent to a dental laboratory.
Once the scan or mold is complete, your dentist fabricates a temporary crown right there in the office. This is usually made from acrylic or a composite resin material and takes only a few minutes to shape and adjust. It’s cemented onto your prepared tooth with a weaker adhesive (intentionally, since it needs to come off easily at your next visit). The whole appointment, from numbing to walking out with your temporary in place, generally runs 45 minutes to an hour, though complex cases can take longer.
How Long You’ll Wear It
The dental lab typically needs 2 to 3 weeks to create your custom permanent crown. Your temporary crown is designed to last exactly that long. It protects the reshaped tooth from sensitivity and damage, keeps neighboring teeth from shifting into the gap, and lets you chew reasonably normally in the meantime.
Wearing a temporary crown beyond that window starts to create problems. The materials aren’t built for long-term use, and extended wear can lead to gum irritation, bacterial buildup around the margins, and gradual shifting of surrounding teeth. If your permanent crown is delayed for any reason, let your dental office know so they can monitor the temporary and replace it if needed.
Eating and Drinking After Placement
Wait at least 30 minutes after your temporary crown is placed before eating anything. This gives the cement enough time to set. Once that window passes, you can eat, but you’ll want to be strategic about it for the entire 2 to 3 weeks you’re wearing the temporary.
Stick to softer foods and chew on the opposite side of your mouth when possible. Sticky foods like caramel or taffy can pull the temporary right off, and very hard or crunchy foods can crack the acrylic. Hot and cold sensitivity is normal for the first few days, so room-temperature foods tend to be more comfortable early on.
If Your Temporary Crown Comes Loose
Temporary crowns fall off more often than you’d expect, precisely because they’re attached with weaker cement. If yours comes loose, try sliding it back into place over the tooth and call your dentist to schedule a re-cementation. Don’t leave it off for days. The exposed, reshaped tooth underneath is vulnerable to sensitivity, decay, and the movement of adjacent teeth. Most dental offices can fit you in quickly for this since it’s a simple fix that takes just a few minutes.
Avoid trying to reattach it with household adhesives. Over-the-counter temporary dental cement from a pharmacy works in a pinch if you can’t get to your dentist right away, but it’s a stopgap, not a solution.
Same-Day Crowns Skip the Temporary Entirely
If the idea of wearing a temporary for weeks doesn’t appeal to you, some dental offices offer same-day crowns using in-office milling technology. These systems take a digital scan of your tooth, then carve a permanent ceramic crown from a solid block right in the office. The entire process, from tooth preparation to permanent crown placement, takes roughly 2 to 4 hours in a single visit, with no temporary needed.
Not every tooth or every type of crown is a good candidate for same-day milling, and not all practices have the equipment. But if avoiding a temporary crown matters to you, it’s worth asking whether your dentist offers this option before your preparation appointment is scheduled.
