Porcelain Inlays & Onlays in Kitchener, ON
Restore & Reinforce Your Smile
Not every tooth problem needs a crown, and not every filling gives you long-term durability. For patients with weakened, cracked, or heavily restored teeth—especially those that endure constant chewing pressure—porcelain inlays and onlays are often the ideal solution. At MI Dental, we are proud to offer this time-tested, highly durable treatment that combines strength, beauty, and preservation of natural tooth structure.
What Are Inlays and Onlays?
Inlays and onlays are sometimes called “indirect fillings” because, unlike a conventional filling that is placed directly into the tooth, these restorations are custom-made in a dental laboratory before being bonded into place.
- Inlays fit within the grooves of the tooth, much like a filling, but are stronger and longer-lasting.
- Onlays cover one or more cusps of the tooth, offering additional reinforcement without the need for a full crown.
Both options are crafted from high-quality porcelain for a lifelike appearance and unmatched durability.
A Little Dental History
Inlays and onlays have been around for generations. “Old school” dentists know their value well—decades ago, porcelain inlays/onlays (and earlier, gold inlays) were the gold standard for restoring back teeth. With the advent of composite resins and chairside CAD/CAM technology, some dentists moved away from this technique because it involves two steps and a lab fee.
However, many experienced practitioners—and patients who’ve had them—will tell you: nothing matches the precision and longevity of a well-made porcelain inlay or onlay.
Why Choose Porcelain Inlays & Onlays Over Direct Restorations?
Compared to conventional direct fillings, porcelain inlays and onlays offer several advantages:
Perfect Occlusal Anatomy – Because they’re designed in the lab, the biting surface is sculpted to perfection, providing an ideal fit with your natural bite.
No Occlusal Adjustment Needed – Direct fillings often require the dentist to shape and adjust the bite after placement. With inlays and onlays, this is already built in, saving chair time and ensuring comfort.
Superior Polish & Form – Porcelain provides a glass-like finish that resists staining, plaque, and wear better than resin fillings.
No Post-Operative Sensitivity – Many patients report less sensitivity compared to composite fillings, especially when large areas of the tooth are involved.
Longevity – Properly made and cared for, porcelain inlays and onlays can last decades, far outlasting most direct restorations.
Inlays & Onlays vs. Crowns
So where do inlays and onlays fit in compared to crowns?
- Less Tooth Preparation – Unlike crowns, which require the removal of more tooth structure to fit around the entire tooth, inlays/onlays are more conservative, preserving as much natural tooth as possible.
- Strength & Durability – They reinforce weakened teeth to withstand daily chewing forces.
- Seamless Appearance – Made from porcelain, they blend in naturally with surrounding teeth.
- Protective Function – They provide coverage and stability without the full encasement of a crown.
In short: inlays/onlays are the perfect middle ground between fillings and crowns.
The Process of Getting an Inlay or Onlay
Getting a porcelain inlay or onlay is a two-appointment process:
Preparation
The decayed or damaged portion of the tooth is removed, and the area is shaped to receive the inlay/onlay. A digital scan is taken and sent to our trusted lab, where your restoration is custom-crafted. A temporary restoration is placed to protect your tooth in the meantime.
Final Placement
At the second appointment, your inlay or onlay is tried in for fit, shade, and comfort. Once approved, it is permanently bonded with a strong dental adhesive, creating a seamless, durable restoration.
Who Is a Candidate?
Porcelain inlays and onlays are an excellent option if you:
- Have a large filling that needs replacement
- Have a cavity too big for a simple filling but not large enough for a crown
- Want a restoration that looks natural and lasts longer
- Grind or clench your teeth (bruxism), which can shorten the life of composite fillings
Fun Fact
Did you know that porcelain inlays and onlays are sometimes nicknamed “the forgotten restoration” in dentistry? While newer materials and technologies have shifted trends, many dentists and patients still swear by them for their accuracy, durability, and beauty. In fact, some porcelain inlays placed decades ago are still fully functional today!
FAQs About Porcelain Inlays & Onlays
1. Do inlays and onlays last longer than fillings?
Yes. While composite fillings may last 5–10 years, porcelain inlays and onlays can last 15–20 years or longer with proper care.
2. Are they stronger than fillings?
Absolutely. Porcelain is much stronger and less prone to wear or fracture than composite resin.
3. Why not just do a crown instead?
Crowns are excellent when more extensive coverage is needed, but they require more tooth reduction. Inlays/onlays preserve more natural structure while still reinforcing the tooth.
4. Will they look natural?
Yes. Porcelain is matched to your tooth color and is highly resistant to staining, offering a seamless blend.
5. Are porcelain inlays/onlays worth the extra time and investment?
For patients looking for longevity, precision, and natural aesthetics, the answer is a resounding yes. They are an investment in both function and beauty.
