Inlays & Onlays
Inlays & Onlays is available at these locations:
Not every damaged tooth needs a full crown, and not every problem can be solved with a simple filling. That in-between zone is exactly where an inlay or onlay does its best work, repairing moderate decay, cracks, or fractures while protecting as much of your natural tooth structure as possible. Each one is custom-made, and at Aesthetic Dentistry we craft them from durable, tooth-colored materials so the finished restoration looks and feels like the tooth you started with.
What they are
Tooth-saving restorations crafted to sit inside or over the cusps of a damaged tooth; they hold up better than fillings yet remove less tooth than crowns.
Who they're for
Anyone with a cracked cusp, moderate decay, or an aging filling due for replacement, as long as enough healthy tooth is still there to build on.
How we help
We shape the tooth precisely, fabricate your restoration in durable tooth-colored materials, then bond it for a secure, lasting fit that keeps your natural tooth intact.
Cracked a tooth or have a filling that's giving out? An inlay or onlay can often rescue the tooth before it needs a full crown.
Inlay or Onlay: How the Two Differ
Dental Inlay
- Sits within the cusps, the raised points on a tooth's chewing surface
- A strong choice for moderate decay or damage on the tooth's biting surface
- Replaces a standard filling when the damage is more than composite alone can handle
- Custom-made to drop precisely into the area your dentist prepares
Dental Onlay
- Reaches over one or more of the tooth's cusps, shielding a wider area
- Comes into play when an inlay isn't enough but a full crown would be overkill
- Often referred to as a "partial crown," since it rebuilds more tooth structure than an inlay does
- Guards the tooth the way a crown would, yet leaves more natural tooth in place
Material Choices and Their Benefits
Material Options
- Porcelain/ceramic: the go-to pick for most patients, blending into your natural tooth color for a seamless look
- Composite resin: a tooth-colored material that bonds readily to the remaining tooth structure
- Gold: exceptionally tough and long-wearing, which is why some patients still favor it for back teeth
- our doctors will recommend the right material for you, weighing where the tooth sits, how you bite, and the look you want
Key Benefits
- Preserves tooth structure: far less of your natural tooth comes away than it would for a full crown
- Durability: these lab-made materials are stronger than standard fillings and last noticeably longer
- Natural appearance: tooth-colored options disappear against the teeth around them
- Precise fit: custom fabrication seals the tooth tightly so bacteria can't sneak in
- Strengthens the tooth: the restoration bonds in place and reinforces what's left of the tooth
What the Procedure Involves
Procedure Steps
- Preparation: your dentist clears away the decayed or damaged part of the tooth, then shapes what remains to hold the restoration
- Impression: a precise mold of the prepared tooth heads to a dental laboratory, where your restoration is custom fabricated
- Temporary: a temporary cover shields the tooth while your custom inlay or onlay is being made
- Placement: at the follow-up visit, that finished restoration is bonded securely to your tooth and polished for a perfect fit
What to Know
- Plan on two visits, usually spaced about 2 weeks apart
- Local anesthesia keeps the preparation step comfortable from start to finish
- Prefer to skip the wait? Some offices complete same-day restorations using CEREC technology, so ask whether that option is available
- Once bonded, the restoration forms a tight seal that helps keep future decay from creeping in underneath
- Afterward, most patients feel little to no discomfort

What Happens at Your Visits
Visit Steps
- Examination: X-rays help us gauge how far the damage reaches and which restoration type suits the tooth
- Discussion: our doctors explain how an inlay, an onlay, and other options compare, then recommend the best approach
- Preparation: the tooth is gently prepared and an impression is taken
- Return visit: your custom restoration is placed, fine-tuned, and polished for a comfortable, natural-feeling bite
Helpful Tips
- Go easy on the temporary; it's there to protect the tooth, not to chew like the final restoration
- A little sensitivity right after placement is normal and tends to settle within a few days
- Brush and floss around the restored tooth exactly the way you treat your natural teeth
- Cared for well, inlays and onlays routinely last 10–30 years
- Coming in for regular checkups lets us keep an eye on the restoration over time
Frequently Asked Questions
Think of it as a scale of coverage. An inlay fills the area between the cusps (the bumps) on a tooth's chewing surface, an onlay reaches across one or more cusps for broader coverage, and a crown wraps the entire visible portion of the tooth.
The practical difference is how much natural tooth each one preserves. Because inlays and onlays restore only the damaged area and leave more of your healthy tooth intact, they sit between a filling and a crown in both coverage and how much preparation they require. In every case, our doctors recommend the most conservative option that will effectively restore the tooth, so you keep as much of your own tooth as the situation allows.
A lot of it comes down to upkeep. Backed by good oral hygiene and regular dental visits, inlays and onlays can last 10 to 30 years, frequently outlasting traditional fillings thanks to the strength of the lab-made materials and how precisely they are bonded into place.
How long yours holds up depends on the material used, the tooth's location, your bite forces, and how well you care for your teeth. Back teeth absorb the most pressure, so grinding or clenching can shorten that range, while a protective night guard can extend it. Catching small issues early at your checkups is the other half of getting the most years from your inlays and onlays.
When the damage is moderate, they usually are. Because inlays and onlays are custom-made in a lab from a precise mold of your tooth, they fit more precisely, rely on stronger materials than direct composite, and actually strengthen the remaining tooth structure rather than simply filling the space.
That said, bigger is not always better. Standard fillings stay the better choice for small areas of decay, where a same-visit composite restoration is more than enough and removing extra tooth to place an inlay would be unnecessary. The goal is always to match the restoration to the damage, and our doctors will tell you honestly which one your tooth actually needs.
They do. Porcelain and composite inlays and onlays are color-matched to your surrounding teeth, so they blend in almost completely, and most people will not be able to tell you have a restoration at all.
Tooth-colored materials also reflect light much the way natural enamel does, which is what keeps the repair from looking flat or obvious, even on a tooth that shows when you smile. For back teeth, some patients still choose gold for its exceptional durability, but when a seamless, natural look is the priority, porcelain or composite inlays and onlays deliver it.
It should not be. Local anesthesia numbs the area before any preparation begins, so you will not feel pain while the tooth is shaped and the impression is taken, and most patients say the experience is a lot like getting a filling.
Because inlays and onlays usually take two visits, you wear a temporary restoration in between, and that is generally comfortable as long as you go easy on it. If any sensitivity follows the final placement, it is typically mild and short-lived, settling within a few days as the tooth adjusts to its new restoration.
Pricing tends to land between a standard filling and a full crown, shifting with the material chosen, whether it is porcelain, composite, or gold, and the size of the restoration. Lab-fabricated work also reflects the custom craftsmanship that goes into each piece.
Because inlays and onlays count as a restorative procedure rather than a purely cosmetic one, most dental insurance plans help cover them. You will get a detailed estimate before treatment at our Orland Park or Frankfort office, and we offer financing options so the cost can be spread into comfortable payments.
Yes, and it is one of the most common reasons patients choose an inlay or onlay in the first place. Large fillings, especially old amalgam ones, do not last forever: over the years they can crack, wear down, or let decay creep in around their edges, and they leave the tooth more fragile than a smaller filling would.
When that happens, upgrading to a custom inlay or onlay removes the failing filling and any new decay, then replaces it with a lab-made restoration that fits precisely and reinforces what is left of the tooth. The result is a stronger, longer-lasting repair that often spares the tooth from eventually needing a full crown.
The best part about inlays and onlays is that caring for them is no different from caring for your natural teeth. A few simple habits keep them in great shape for years:
- Brush twice daily and floss daily, giving the restored tooth normal attention.
- Keep up regular checkups and cleanings with our doctors so the restoration can be monitored over time.
- Steer clear of biting on extremely hard objects like ice or hard candy.
- Ask about a night guard if you grind or clench your teeth, since that protects the bond.
Because the restoration is sealed tightly to the tooth, good daily hygiene also keeps decay from sneaking in underneath, which is one of the main reasons inlays and onlays last as long as they do.
