What Exactly Are Inlays and Onlays?
Think of an inlay like a custom-made puzzle piece that fits right into the grooves of your tooth, between the cusps (those pointed parts on top). It’s used when the damage or decay is too much for a traditional filling, but the tooth structure around it is still strong.
An onlay is slightly more involved. It covers one or more of those cusps and can extend down the sides of the tooth. If a filling is like patching a hole in drywall, an onlay is more like replacing a section of the wall itself. It helps add strength back to the tooth.
Both are created from a mold of your tooth and bonded directly onto it. They’re typically made from porcelain, which gives us two major advantages: strength and a natural look that actually matches your other teeth.
Why Choose an Inlay or Onlay?
Here’s the thing about traditional silver fillings, they don’t bond to your tooth the way you might think. They just sort of sit there, packed into the hole. Over time, that can actually weaken the tooth structure around it. And if you’ve ever experienced that sharp sensation when something cold hits an old filling, you know exactly what I’m talking about.
Inlays and onlays are different. Because they bond directly to the tooth, they actually reinforce it. You get:
- Strength – The bond often makes the tooth up to 75% stronger than with a traditional filling
- Longevity – With good care, they typically last 10-15 years or longer
- Precision – They’re custom-crafted to fit your tooth exactly, no guesswork
- Natural appearance – Porcelain can be matched to your tooth color beautifully
For teeth that have had root canals or large fillings in the past, an onlay could be the perfect middle-ground solution. It protects what’s left of your natural tooth without removing the healthy structure you’d need to sacrifice for a crown.
What to Expect If Dr. Parnaik Recommends One
If you’ve never had one before, the process is pretty straightforward. It usually takes two visits.
First visit: Dr. Parnaik will remove any decay or old filling material and prepare the tooth. She takes an impression, using digital technology that’s far more comfortable than the old goopy stuff, and places a temporary restoration to protect your tooth while your permanent one is being crafted.
Between visits: A dental lab creates your custom inlay or onlay from that impression.
Second visit: You come back, Dr. Parnaik removes the temporary, checks the fit of your new restoration, and bonds it permanently in place. You could walk out with a tooth that’s restored, stronger, and looking completely natural.
Are You a Candidate?
The short answer? It depends on your specific situation. Inlays and onlays work best when:
- There’s too much damage for a filling, but the tooth structure is still largely intact
- You have an old, failing filling that needs replacement
- The tooth isn’t damaged enough to need a full crown
- You want a metal-free, natural-looking restoration
During your exam at our Medford office, Dr. Parnaik will walk you through exactly what she’s seeing and why she might recommend one option over another. That’s just how we do things here. No surprises, no pressure, just honest conversation about what makes sense for your smile.
