Hey there! If you've ever sat in a dental chair and heard the words, "Well, it's a bit too big for a regular filling, but maybe we don't need a full crown yet," you might have felt like you were stuck in dental limbo. It's like being told your car needs more than an oil change but doesn't quite need a whole new engine.
Enter the "Goldilocks" of the dental world: Inlays and Onlays.
At Pomona Dental Group, we're all about finding the perfect fit for your smile. We don't believe in "one size fits all" solutions because your teeth are as unique as your fingerprint. If you're looking for a dentist in Pomona who can offer a high-tech, durable, and conservative way to save your tooth, you've come to the right place.
Let's dive into why these custom restorations are the superheroes of modern dentistry and why they might be the best thing to happen to your mouth since the invention of the electric toothbrush.
The "Middle Ground" Problem
Most of us are familiar with the standard filling. You get a little cavity, we clean it out, and we pop in some composite resin. Easy peasy. On the other end of the spectrum, we have the dental crown — a "cap" that covers the entire tooth when things have gone south due to a major fracture or massive decay.
But what happens when you're right in the middle?
If we try to put a massive filling in a tooth that has lost a significant amount of its structure, the filling might not be strong enough to handle the pressure of you enjoying that sourdough bread or a handful of almonds. On the flip side, we always want to keep as much of your natural tooth as possible. A crown requires us to shave down more of the tooth to make room for the cap.
This is where inlays and onlays shine. They allow us to be conservative while providing the strength of a lab-fabricated restoration.

So, What Exactly is an Inlay?
Think of an inlay as a high-end, custom-made puzzle piece.
When the damage or decay is located within the "cusps" (those little mountain peaks on your chewing surface) of your tooth, an inlay is the way to go. Unlike a traditional filling that is packed into the tooth and hardened while you're in the chair, an inlay is crafted in a professional dental lab to match the exact dimensions of the space we've prepared.
Because it's made outside of the mouth from durable materials like porcelain or ceramic, it doesn't shrink or expand like some filling materials might. It's bonded into place, creating a seamless, airtight seal that protects your tooth from future bacteria parties.
And What About the Onlay?
If an inlay is a puzzle piece for the middle of your tooth, an onlay is its big brother that covers the edges.
An onlay is used when the damage extends to one or more of the cusps. In the past, this kind of damage almost always meant you were getting a full crown. But thanks to modern technology at our dental office in Pomona, we can use an onlay to "reconstruct" the biting surface without having to cover the entire tooth.
Because onlays cover the chewing surface, they are sometimes called "partial crowns." They provide incredible strength and are perfect for those "oops" moments when you bite down on something hard and a corner of your molar decides to check out.
For cases where damage is more extensive and an onlay isn't enough, a full dental crown may be the right next step. Dr. Sandoval will walk you through both options so you can make an informed decision.
Why We Love Inlays and Onlays (And You Will Too)
At Pomona Dental Group, we're big fans of any tech that lets us save your natural tooth structure. Here's why we often recommend these "Goldilocks" fixes:
1. The Longevity Factor
Standard fillings are great, but they usually last anywhere from 5 to 15 years. Inlays and onlays are the marathon runners of the dental world. When properly cared for, they can last up to 30 years! They are made of tough stuff — usually high-grade porcelain, ceramic, or even gold — that can stand up to the daily grind of chewing.
2. They Keep Your Tooth Strong
Traditional fillings can actually weaken a tooth slightly because they rely on the remaining walls of the tooth to hold them in place. In contrast, inlays and onlays are bonded directly to the tooth with high-strength resins. This process can actually increase the strength of the tooth by up to 75%.
3. Precision Fit
Because these are custom-molded to your tooth, the fit is incredibly precise. This makes them much easier to clean than a large filling, which can sometimes have "overhangs" or rough edges that trap plaque. A better fit means a lower chance of getting a new cavity under the restoration.
4. Aesthetics (The "Invisible" Fix)
No one wants a mouth full of silver or dark spots. Our porcelain inlays and onlays are color-matched to your surrounding teeth. They look so natural that even you might forget which tooth has the restoration after a few weeks. It's the ultimate high-tech "incognito" repair.

What to Expect: The Procedure
If we decide together that an inlay or onlay is the right move for your smile, the process is smooth and straightforward. It usually takes two visits to our Pomona office.
Visit 1: Preparation and Impressions
First, we make sure you're comfortable. We'll remove any old fillings or decay and "prep" the tooth. Then, we take a highly accurate impression. This serves as the blueprint for the lab to create your custom piece. Before you leave, we'll place a temporary filling to keep your tooth safe and comfortable while the lab works its magic.
Visit 2: The Final Fit
Once your custom inlay or onlay arrives, you'll come back in. We'll remove the temporary and check the fit and color of the new piece. Once we're both happy with how it looks and feels, we bond it permanently to your tooth and give it a final polish. You'll walk out with a tooth that's basically as good as new!

Taking Care of Your Investment
Once your new inlay or onlay is in place, caring for it is simple: treat it like a regular tooth!
- Brush twice a day with a soft-bristled brush.
- Floss daily. This is huge for preventing decay around the edges of any restoration.
- Keep your regular cleanings. Visiting your dentist in Pomona every six months allows us to check the integrity of your restorations and catch any tiny issues before they become big, expensive problems.
Is an Inlay or Onlay Right for You?
Choosing the right dental treatment shouldn't feel like a guessing game. During your exam at Pomona Dental Group, we use advanced imaging — sometimes even our CBCT imaging — to see exactly what's going on beneath the surface.
If your tooth is too far gone for an inlay or onlay, we might talk about other options like a full dental crown or, in more severe cases, extractions. But our goal is always the most conservative treatment that will give you the best long-term result.
A Note on Financing
We know that "custom-made" and "high-tech" can sometimes sound like "expensive." While inlays and onlays do cost more than a standard filling upfront, their 30-year lifespan actually makes them a very cost-effective choice in the long run. To make things easier, we offer various financing options and work with many insurance providers to ensure you get the care you need without the stress.

Frequently Asked Questions About Inlays and Onlays in Pomona
What is the difference between an inlay and an onlay?
An inlay fills the space between the cusps (the raised points) on the chewing surface of your tooth, while an onlay extends further to cover one or more cusps. Think of an inlay as a precision fill and an onlay as a partial cap. Dr. Sandoval will assess your X-rays and the extent of damage to recommend the right option for your specific tooth.
How long do inlays and onlays last?
With good oral hygiene and regular dental visits, inlays and onlays can last 20 to 30 years — significantly longer than traditional fillings. The longevity depends on the material used (porcelain, ceramic, or gold) and how well you care for them. Our patients at Pomona Dental Group consistently report excellent long-term results.
Do inlays and onlays hurt?
The procedure is performed under local anesthesia, so discomfort during treatment is minimal. You may notice some mild sensitivity after the anesthesia wears off, but most patients feel comfortable within a day or two. Dr. Sandoval's gentle technique and calm chairside manner help ensure the experience is as relaxed as possible.
Is an inlay or onlay better than a crown?
Inlays and onlays are the more conservative choice when the tooth still has a healthy amount of natural structure remaining — they require less tooth reduction than a full dental crown. A crown is generally preferred when the damage is more extensive, covering most of the tooth. Dr. Sandoval will always recommend the least invasive option that provides a durable, lasting result.
Does insurance cover inlays and onlays in Pomona?
Many dental insurance plans cover a portion of inlay and onlay costs, typically classifying them as major restorative procedures with 50% coverage after your deductible. Coverage varies widely by plan, so our team will review your benefits upfront and provide a clear cost estimate before treatment begins. We also offer flexible financing options to make care affordable.
How many appointments does an inlay or onlay take?
Most inlay and onlay restorations require two appointments: the first to prepare the tooth and take impressions, and the second (about two weeks later) to bond your custom-fabricated piece permanently into place. Each visit is typically under an hour. Dr. Sandoval keeps the process efficient and communicates every step so you always know what to expect.
