Inlays and Onlays in Chattanooga, TN
When a cavity is too large for a filling but the tooth doesn’t need a full crown, an inlay or onlay is often the right middle option. Dr. Rollings will show you what we see on the camera and explain why it’s the right call before we do anything.
When an Inlay or Onlay Is the Right Repair
Inlays and Onlays in Chattanooga TN are a category of restoration that sits between a filling and a crown. They’re made in a lab from porcelain or composite, bonded to the tooth, and shaped to replace exactly the part of the tooth that’s damaged. Nothing more.
Most patients arrive at this conversation one of two ways. Either an old amalgam filling has started to fail and the surrounding tooth is cracking around it, or a new cavity is too wide or too deep for a standard filling to hold up over time. In both cases, the question is the same: how much of the tooth do we keep, and how do we protect what’s left?
An inlay fits inside the cusps of the tooth, in the chewing surface. An onlay covers one or more of the cusps themselves. Both are bonded in place and shaped to match how your teeth actually meet when you chew. The goal is a repair that holds up for years without grinding down healthy tooth structure you didn’t need to lose.
How an Inlay or Onlay Differs from a Filling or a Crown
A filling is placed in one visit, soft, and hardened in the mouth. It works well for small to moderate cavities. Once the damaged area gets wide enough, though, a filling starts to flex when you bite down, and that flex eventually cracks the tooth around it. That’s the point where we stop recommending a larger filling and start talking about an inlay or onlay.
A crown is the other end of the spectrum. It covers the entire tooth above the gumline, which means we have to reduce the tooth on all sides to make room for it. Crowns are the right answer when a tooth is structurally compromised or has had a root canal. They’re overkill when the damage is contained to the chewing surface and one or two cusps.
Inlays and onlays land in between. They’re milled or pressed from a single piece of porcelain or composite, so they don’t flex the way a filling does. And because we only remove the damaged portion of the tooth, you keep more of your own enamel. That matters over a lifetime of dental work, especially if you’re someone whose teeth have already been restored once or twice.
What the Inlay and Onlay Process Looks Like at Wilcox Family Dental
The first visit starts with a digital X-ray and a look with the intraoral camera. If we’re recommending an inlay or onlay, we’ll show you on the screen exactly what we’re seeing: the crack, the failing filling, the depth of decay. You should be able to point to the same spot we’re pointing to before you agree to treatment.
If you decide to move forward, we remove the damaged tooth structure and the old filling material, clean the tooth, and take an impression. The impression goes to one of the local labs we partner with, where your inlay or onlay is custom-made to fit your tooth and your bite. In the meantime, you wear a temporary.
At the second visit, we try the restoration in, check the fit and the bite, and bond it permanently. Most patients are numb for the bonding appointment but recover quickly. You can usually eat normally the same day, with the caveat that the tooth may be sensitive to cold for a few weeks while it settles in.
What's Included When You Get an Inlay or Onlay With Us
Every inlay and onlay case at our office starts with the same baseline. We take digital X-rays, look at the tooth with the intraoral camera, and walk you through what’s there. If there are two reasonable ways to treat the tooth (say, a large filling now versus an onlay, or an onlay versus a crown), we tell you which we’d choose and why. We also tell you what happens if you wait six months instead of treating it now.
Before we start, you get a written estimate. That includes what your insurance is expected to cover, what your portion is likely to be, and what financing looks like if you need it. We work with CareCredit, Cherry, and QuickPay, and we’re happy to walk through the math with you at the front desk.
The restoration itself is made by one of the local labs we trust, not shipped overseas. If something doesn’t feel right at the second visit (the bite is high, the contact with the next tooth is tight, anything), we adjust it before you leave. None of this is a favor. It’s how the work is supposed to be done.
Insurance, Medicaid, and Payment for Inlays and Onlays
Inlays and onlays are usually covered as a major restorative service by dental insurance, often at a similar percentage as crowns. The exact coverage depends on your plan, your annual maximum, and whether you’ve used benefits elsewhere this year. We accept Medicaid and all major insurance providers, and we’ll verify your benefits before treatment so you know what to expect.
If there’s a gap between what insurance covers and the cost of the restoration, we have options. CareCredit and Cherry offer financing with terms that vary by plan, and QuickPay is available for patients who want to pay in installments without applying for outside credit. We’ll put the numbers in writing before you commit to anything.
If cost is part of how you’re deciding when or whether to do this, say so out loud. Sometimes the right answer is to treat the tooth now before it cracks further and turns into a crown or root canal. Sometimes the right answer is to monitor it for a few months. We’ll tell you honestly which one applies to your tooth.
Why Inlays and Onlays Are Worth Considering
The longer a tooth stays mostly your own tooth, the better. Inlays and onlays let us repair real damage without reducing the entire tooth for a crown, which means more of your enamel stays where it belongs. Porcelain restorations also resist staining and don’t expand or contract the way metal fillings do, so the tooth around them is less likely to crack over time.
If you’ve had a large filling in a back molar for fifteen or twenty years and it’s starting to look dark around the edges, that’s often the early sign that the seal is failing. Catching it at the inlay or onlay stage, before the tooth fractures, is a meaningful difference. A cracked cusp can usually be saved. A vertical crack down the root usually cannot.
