What Are Inlays & Onlays?
Inlays and onlays are custom restorations made from porcelain or composite resin, used to repair decayed or damaged areas of a tooth. They’re fabricated in a dental lab for a precise fit, then bonded securely into place.
- Inlays fit within the cusps (the raised points) of a tooth, similar to a large filling
- Onlays cover one or more cusps and extend over the chewing surface, sometimes called a “partial crown.”
These restorations are ideal for molars and premolars and are a great alternative to tooth-colored fillings when more durability is needed.
Benefits of Inlays & Onlays
- Stronger and more durable than traditional fillings
- Preserve more of your natural tooth than a full crown
- Seamless fit and appearance with your smile
- Resistant to staining and wear
- Custom-crafted for long-term results
- Bonded to the tooth for added strength and protection
We often recommend inlays and onlays when a tooth has moderate decay, old worn-down fillings, or minor fractures.
When Are Inlays or Onlays Needed?
These restorations are most appropriate when:
- A cavity is too large for a filling, but a crown would remove too much healthy tooth
- A tooth has been cracked or worn from grinding
- An old amalgam filling has weakened or deteriorated
- A back tooth needs reinforcement, but not full coverage
We’ll assess your needs with a thorough exam and digital imaging, then help you decide whether an inlay, onlay, or crown is best for your case.
Our Inlay & Onlay Procedure
Step 1: Comprehensive Evaluation
During your visit, we’ll examine the damaged tooth using digital X-rays to assess the extent of decay or fracture.
Step 2: Tooth Preparation & Impressions
The affected area is cleaned and prepped, then a digital scan or impression is taken to design your custom inlay or onlay.
Step 3: Temporary Protection
We place a temporary restoration while your final piece is being fabricated by a trusted dental lab.
Step 4: Final Placement
At your follow-up visit, we bond the inlay or onlay in place and polish it for a perfect match to your tooth and bite.
The result is a strong, natural-looking restoration that blends beautifully with your smile, often lasting longer than large fillings.
Caring for Inlays & Onlays
With proper care, inlays and onlays can last 10–20 years or more. Here’s how to keep them in top shape:
- Brush and floss daily
- Avoid chewing hard objects (like ice or pens)
- Use a nightguard if you grind your teeth
- Keep up with regular dental cleanings and exams
