Porcelain Inlays and Onlays in Beverly Hills
Porcelain Inlays and Onlays
A conservative alternative to a full crown. Custom porcelain that covers only the damaged part of the tooth, so more of your own structure stays where it is.
Why Not Just Put a Crown On It?
When a tooth is too damaged for a filling, the default in most practices is a crown. A crown means reducing the tooth on all sides to a stump, removing a significant amount of healthy structure to make room for it. An inlay or onlay covers only the part that actually needs covering. An inlay sits within the cusps of the tooth. An onlay extends over one or more cusps where they need protecting. Both are made from solid porcelain in a laboratory, then bonded into place, which means the restoration and the tooth work as one unit. Where a tooth can take an onlay rather than a crown, that is what Dr. Shir will recommend, because the enamel you keep is not replaceable.
INLAYS, ONLAYS AND WHEN THEY ARE USED
What they are, when they suit a tooth better than the alternatives, and what to expect from them.
What Is a Dental Inlay?
A custom porcelain restoration that fits within the cusps of a back tooth, replacing the central chewing surface. Used where a cavity is too large for a composite filling but the cusps themselves are sound and do not need covering.
What Is a Dental Onlay?
Similar to an inlay but extending over one or more cusps to protect them. Used where a cusp is cracked, undermined by decay or weakened, and needs covering rather than just filling around. Sometimes called a partial crown.
When a Filling Is Not Enough
Large composite fillings flex under chewing load and can leak at the margins over time. Once a cavity passes a certain size, a bonded porcelain restoration distributes force across the tooth far better and holds its margin longer.
Preserves More of Your Tooth
The main reason we use them. A full crown requires reducing the tooth on every surface. An inlay or onlay removes only the damaged structure plus what is needed for the restoration to bond, which can be considerably less.
Strengthens the Remaining Tooth
Because porcelain is bonded to the tooth rather than cemented over it, the restoration and the remaining structure function together. An onlay covering a weakened cusp reduces the risk of that cusp fracturing under load.
Metal-Free and Natural in Appearance
Solid porcelain, shaded to your own teeth. No metal base, so there is no grey line appearing at the gum margin as the tissue recedes over the years, and nothing that shows when you laugh.
Resists Staining and Wear
Porcelain holds its colour and its polish in a way composite does not. It does not pick up stain from coffee, tea or red wine, and the surface stays smooth rather than dulling over time.
Made From a Digital Scan
Your tooth is scanned with our intraoral scanner rather than an impression tray, so the restoration is made from an accurate digital record. The fit at the margin is what decides how long it lasts, and that is where accuracy matters most.
How Long They Last
Porcelain inlays and onlays commonly serve ten to fifteen years and often longer. Longevity depends on the size of the restoration, how heavily you bite, and whether you grind. Where grinding is present, a night guard is part of the plan rather than an afterthought.
INLAY OR ONLAY: WHICH YOUR TOOTH NEEDS
The difference is how much of the tooth needs covering, and that is decided by what the examination and X-ray show rather than by preference.
PORCELAIN INLAY:
Fits within the cusps of the tooth, replacing the chewing surface between them. Suited to a large cavity where the surrounding cusps are still strong. Less tooth is prepared than for an onlay, and considerably less than for a crown.
PORCELAIN ONLAY:
Extends over one or more cusps to protect them. Suited to a tooth with a cracked or weakened cusp, or one that has been root treated and needs the chewing load spread across the whole tooth. It does the protective job of a crown while keeping more of your tooth intact.
WHY PATIENTS CHOOSE US FOR INLAYS AND ONLAYS
Most practices reach for a crown. We reach for an onlay wherever the tooth allows it, because the structure you keep cannot be put back.
Conservative by Default
We remove what the restoration requires and no more. Where an onlay will do the job of a crown, that is what we recommend, even though it is the more demanding restoration to prepare and fit.
Digital Scanning
An intraoral scanner rather than impression trays, so nothing sets in your mouth and the laboratory works from an accurate digital record. Fit at the margin is what decides longevity.
Metal-Free Materials
Solid porcelain throughout, shaded to your own teeth. No metal base and no dark margin appearing at the gum line as the years pass.
30+ Years of Experience
More than three decades of restorative practice. Preparation for an inlay or onlay is more exacting than for a crown, and the margin design is where the experience shows.

BEFORE YOU AGREE TO A CROWN, GET A SECOND OPINION
If you have been told a tooth needs a crown, it is worth finding out whether an onlay would do the same job. Not every tooth can take one, and we will tell you honestly which yours is. Where it can, you keep structure that cannot be replaced later. Book an assessment with Dr. Shir.
FREQUENTLY ASKED QUESTIONS ABOUT INLAYS AND ONLAYS
The questions patients ask most often before treatment.
What is the difference between an inlay, an onlay and a crown?
An inlay sits within the cusps of the tooth. An onlay extends over one or more cusps to protect them. A crown covers the entire tooth, which means reducing it on every surface. The three represent increasing amounts of coverage and increasing amounts of tooth removed, and the right one is whichever gives adequate protection with the least preparation.
How long do porcelain inlays and onlays last?
Commonly ten to fifteen years and often longer, depending on the size of the restoration, how heavily you bite and whether you grind. Porcelain resists staining and wear well. What usually ends a restoration is decay at the margin, which is why daily cleaning and regular checkups matter more than the material itself.
How many visits does treatment take?
Usually two. At the first, the tooth is prepared under local anaesthetic, a digital scan is taken and a temporary is fitted. The porcelain is then made in the laboratory. At the second, it is tried in, bonded, and your bite adjusted. Around two to three weeks between appointments.
Are inlays and onlays covered by insurance?
They are usually treated as restorative rather than cosmetic, so most plans contribute, though some classify them differently from crowns and the level varies. You receive a written figure before treatment begins, and financing is available.
