Hey there! If you’ve been looking into fixing a chipped or worn down back tooth, you’ve probably heard the terms “inlays” and “onlays” thrown around. But here’s the thing I get asked all the time (both from dentists I work with and regular folks): “Do inlays and onlays need more than one trip to the dentist?” As someone who’s been supplying dental inlays and onlays for years, I’ve seen how this process works firsthand—and it’s way simpler (and sometimes even faster) than most people think. Let’s break it down, no fancy jargon, just real talk. Inlay/Onlay
First, let’s make sure we’re on the same page about what inlays and onlays actually are, because a lot of folks mix them up with crowns or fillings. A filling is that go-to fix for a small cavity—you know, the dentist drills out the decay, packs in composite or amalgam, and you’re done. Inlays and onlays? They’re custom-made, permanent restorations for when the damage is a little bigger than a filling but not bad enough for a full crown. Inlays fit inside the tooth’s grooves, like a little puzzle piece, while onlays cover one or more of the tooth’s cusps (those pointy bits you use to chew). They’re way stronger than fillings, look more natural, and last way longer—we’re talking 10-20 years if you take care of ’em.
Now, back to the main question: multiple visits? Let’s start with the old way of doing things, because that’s probably where the “multiple trips” myth comes from. Not that long ago, if you needed an inlay or onlay, your dentist would have to take a mold of your tooth with that icky goopy stuff that makes you gag. Then they’d send that mold off to a lab to make your custom restoration. That process took at least a week—so you’d come in first to prep the tooth, get a temporary (usually a soft plastic or filling that falls out easy), then come back a second time a week later to swap the temp for the real inlay/onlay. That’s two visits, minimum. But here’s the twist: today, tons of dentists are using digital technology that cuts that down—sometimes to one single visit.
Wait, how does that work? Let’s walk through the modern one-visit process step by step, because it’s wild. First, your dentist will numb the area (standard, same as a filling), then trim the damaged part of your tooth just enough to make space for the inlay or onlay—no over-drilling, which is a win for your natural tooth. Instead of the goopy mold, they use a tiny wand that takes a 3D picture of your tooth in seconds. That digital scan gets sent to a computer program that designs your custom inlay or onlay right there in the office. Then, there’s this little milling machine (we supply a lot of the materials these machines use—think high-quality ceramic or resin that’s super durable) that carves the restoration from a solid block in like 15-20 minutes. Once it’s done, your dentist will fit it, check that it fits just right, bond it to your tooth, and you’re out the door—no temporary, no second trip. That’s a game-changer for busy people who can’t take time off work or school.
But hold on—does that mean all inlays and onlays are one visit? Nope, that’s where the “sometimes multiple visits” part comes in, and it’s not just about technology. Let’s talk about when you might need two (or even three) trips, because that’s important for you to know too. First, if a dentist doesn’t have that digital milling machine in their office, they have to use the lab method I mentioned earlier. That’s super common in smaller towns or practices that haven’t invested in the tech yet—so that’s two visits, no way around it. Second, even if they have the tech, some cases are trickier. Like, if your cavity is really deep, or if the tooth has a lot of old fillings that need to be removed, your dentist might want to wait a little while to make sure the tooth is healthy before putting on the permanent inlay/onlay. Sometimes that means a first visit to prep, a week or two of waiting, then a second visit to place it. Rarely, if there’s an infection that needs fixing (like a root canal), you might need a third visit—but that’s not specific to inlays/onlays, that’s just standard for any dental work that needs extra care.
Here’s something I’ve learned over the years: most people don’t mind a second visit if it means a restoration that lasts way longer than a filling. But no one likes the wait, or the temporary falling out right before the second trip (I’ve had customers tell me horror stories about that—someone’s temp inlay fell out at a concert, another had it slide out while eating a burger, total nightmare). That’s why digital one-visit inlays and onlays are blowing up right now—they eliminate the temp mess and cut the process way down. But let’s be real, for the patients who live in rural areas where there’s no dentist with a milling machine, or who can’t afford the digital tech? The old lab method is still the go-to, and that means two visits. It’s not that it’s worse—it’s just different.
Another thing people don’t talk about: inlays and onlays are way more flexible than crowns when it comes to how many visits you need. Crowns almost always need two visits because they’re big, and you have to send the mold to a lab no matter what. But inlays/onlays, since they’re smaller, are perfect for that one-visit digital process. I’ve had so many dental clients tell me that their patients are surprised when they leave with the real restoration, not a temporary. Like, one dentist I work with in Chicago said his patients now ask for the “one-day inlay” specifically, because they hate waiting. That’s the kind of feedback that makes supplying these restorations worth it, ya know?
Wait, let’s also clear up a myth that goes with the “multiple visits” question: people think more visits mean more pain, or more issues. But that’s not true. The first visit, whether it’s for a one- or two-process, is just prep—numbing, trimming the tooth, getting the mold or scan. The pain is basically the same as a filling. The second visit (for the lab method) is just placing the restoration, which is also low-pain. The only difference is how long you have to wait. The actual number of visits doesn’t affect how good the restoration is—what matters is that it’s custom-fit, which both methods do.
Now, let’s talk from my side as an inlay/onlay supplier. A lot of dentists reach out to me because they want to offer the one-visit service, but they need reliable materials for the milling machines. The stuff we supply is lab-tested, so the restorations carve perfectly, fit right, and last as long as they should. We’ve seen that when dentists use high-quality materials, their patients come back happy—they don’t have to redo the inlay in 5 years, they don’t have sensitivity issues, and they tell their friends. That’s why we focus on making materials that work for both the digital one-visit process and the traditional lab method—because not every office has the same setup.
So, to wrap up the main question: Do inlays and onlays require multiple visits? The answer is… it depends. If your dentist has digital scanning and milling tech, and your case is straightforward, you can probably get it done in one visit. If your dentist doesn’t have that tech, or your case is a little more complex (deep cavity, infection, etc.), you’ll need two (maybe three) visits. That’s it—no hard and fast rule, but way less than a crown, which is almost always two.
I know a lot of you reading this might be dentists looking for a reliable supplier, or maybe a patient trying to decide between a filling, inlay, or onlay. If you’re a dentist who wants to offer custom, durable inlays and onlays (whether for one-visit digital work or lab-process restorations), reach out to us—we’ve got the materials you need, the support to help you set up if you’re new to digital milling, and we work with practices of all sizes, from small local ones to big clinics. For patients, if you’re asking your dentist about inlays or onlays, just ask them: “Do you offer one-visit options for these?” It’s a simple question that can save you a week of waiting and a second trip.
At the end of the day, inlays and onlays are such a great option for preserving your natural teeth—way better than crowns for smaller damage. The number of visits doesn’t have to be a headache, especially now that tech is making it easier. Whether it’s one trip or two, the goal is to get a restoration that works, looks natural, and lasts.
