Inlays and Onlays in Northridge
Not every cavity is small enough for a filling, but not every damaged tooth needs a full crown either. Inlays and onlays fill that middle ground, restoring teeth with damage too extensive for a standard filling while still preserving more of the natural tooth than a crown would require.
They’re custom-made outside the mouth and then bonded into place, giving a precise, durable fit for the exact damage present. At Clove Dental Northridge office, we assess how much of the tooth is affected before recommending which restoration actually makes sense.
What Are Inlays and Onlays?
Inlays and onlays are custom-fabricated restorations used to repair teeth with moderate damage or decay, positioned between a filling and a full crown in terms of how much of the tooth they cover. An inlay fits within the grooves on the biting surface of the tooth, while an onlay extends further, covering one or more of the cusps, the raised points on the tooth’s surface. Both are typically made from porcelain, composite resin, or gold, crafted in a lab or milled on-site from an impression or digital scan, then bonded securely to the tooth. Because they’re custom-made rather than shaped directly in the mouth like a filling, they tend to offer a stronger, longer-lasting fit for larger areas of damage.
Benefits of Inlays and Onlays
Preserves more natural teeth
Less of the tooth needs to be removed compared to preparing for a full crown.
Stronger than a large filling
Custom fabrication provides better durability for damage too extensive for standard fillings.
Precise, long-lasting fit
Made outside the mouth from an exact impression, they fit more precisely than a filling shaped in place.
Blends in naturally
Porcelain and composite versions are shaded to match your surrounding teeth.
Signs You Might Need an Inlay or Onlay
A few common situations where this restoration comes up as an option.
- A cavity too large for a standard filling- Once decay extends past a certain point, a filling may not hold up long-term.
- A cracked or fractured cusp- Damage to the raised points of a tooth is often better addressed with an onlay than a filling.
- A failing older filling- If a large existing filling is breaking down, replacing it with an inlay or onlay can offer more durability.
- Tooth damage that doesn’t require a full crown- When enough healthy structure remains, a crown may be more than necessary.
- A desire to avoid removing extra healthy tooth- Patients who want a more conservative option than a crown often ask about this route.
Process of Getting an Inlay or Onlay
Getting an inlay or onlay typically involves two visits, each designed to be comfortable and efficient:
Exam and evaluation
We assess the extent of the damage to determine whether an inlay, onlay, or different restoration fits best.
Preparing the tooth
Any decayed or damaged tissue is removed and the tooth is shaped to receive the restoration.
Taking an impression or scan
An exact mold or digital scan captures the tooth’s shape for a precise custom fit.
Temporary restoration
A temporary filling protects the tooth while your permanent inlay or onlay is fabricated.
Bonding the final piece
Once ready, the custom restoration is checked for fit, adjusted if needed, and bonded permanently in place.

FAQs
-
How is an inlay different from an onlay?
An inlay fits within the grooves on the biting surface of a tooth, while an onlay extends further to cover one or more cusps, the raised points on the tooth.
-
How do inlays and onlays compare to a regular filling?
They're custom-made outside the mouth for a more precise fit and tend to hold up better for larger areas of damage than a filling shaped directly in the tooth.
-
Do I need a crown instead?
Not necessarily. Inlays and onlays are often recommended specifically to avoid removing the extra tooth structure a crown would require, when enough healthy teeth remain.
-
How long do inlays and onlays last?
With good care, most last 10 to 15 years or longer, similar to other durable restorations like crowns.
-
Does getting an inlay or onlay hurt?
The tooth is numbed before any preparation, so the procedure itself is comfortable. Mild sensitivity afterward is normal and typically brief.
