When a tooth has more damage than a regular filling can fix — but isn’t damaged enough to need a full crown — dentists may recommend an inlay or onlay. These custom-made restorations help protect your tooth while preserving as much of the natural structure as possible.
Here’s what Canadian patients need to know about inlays and onlays.
🦷 What Is an Inlay?
A dental inlay fits inside the cusps (edges) of a tooth. It’s used when a cavity is too large for a filling but doesn’t affect the pointed parts of the tooth.
Key features:
- Made from porcelain, composite resin, or gold
- Stronger and longer-lasting than a regular filling
- Custom-designed to match your tooth’s shape and colour
🦷 What Is an Onlay?
A dental onlay is similar, but it covers one or more cusps of the tooth. It’s sometimes called a “partial crown” because it offers more coverage without needing a full crown.
Benefits of onlays:
- Conserves more of your natural tooth than a crown
- Provides strength and protection for damaged areas
- Blends in naturally with your smile
What Is the Procedure Like?
Inlays and onlays typically require two visits:
- The dentist cleans out the decay and takes a digital or physical impression.
- A custom inlay or onlay is made in a dental lab.
- At your second visit, it’s bonded permanently in place.
Same-day options may be available at some clinics with advanced technology.
🛌 When Are They Recommended?
Your dentist may recommend an inlay or onlay if:
- The cavity is too large for a standard filling
- You want a more durable, long-lasting restoration
- You have cracked or weakened areas on a molar
