Not Every Tooth Needs a Crown: When an Inlay or Onlay Is the Better Option

When a tooth has moderate decay or damage, many patients assume a full crown is the only solution. But depending on the size and location of the problem, a more conservative and cost-effective treatment may be available: inlay or onlay restoration.

At Dr. Stephen Coates, DDS, we recommend inlays and onlays for patients who need more than a filling but don’t require a full crown. They’re strong, natural-looking, and designed to protect your tooth structure for years to come.

4 DENTAL PROBLEMS INLAYS AND ONLAYS CAN SOLVE

While crowns are often thought of as the default solution for tooth damage, inlays and onlays can be a better match for many situations—especially when the damage is too large for a filling but not extensive enough to justify removing more tooth structure.

Here are a few common cases where inlays and onlays are ideal:

1. Large cavities that can’t be treated with a filling
   When decay extends beyond what a filling can safely restore, an inlay or onlay provides better coverage and long-term support without needing a full crown.
2. Fractured or chipped teeth
   Minor to moderate fractures can often be repaired with a custom onlay that reinforces the biting surface of the tooth and restores its function.
3. Old or failing fillings
   Inlays and onlays are excellent options for replacing old metal fillings or large composite fillings that have begun to break down.
4. Cosmetic tooth improvements
   These restorations aren’t just functional—they also blend beautifully with your natural teeth. Patients who want to replace old, discolored restorations often choose inlays or onlays for an aesthetic boost.

Because inlays and onlays are custom-made to match your tooth’s shape and color, they restore both strength and appearance with a minimal impact on your natural structure.

3 REASONS PATIENTS PREFER INLAYS AND ONLAYS OVER CROWNS

Still wondering whether an inlay or onlay is the right option for you? Here’s why many patients—and dentists—recommend them over crowns when appropriate.

1. They preserve more of your natural tooth
   Unlike crowns, which require reshaping the entire tooth, inlays and onlays fit snugly into the problem area without removing healthy enamel.
2. They offer a stronger, longer-lasting alternative to fillings
   Composite fillings can weaken over time, especially on molars. Inlays and onlays are made from stronger materials like porcelain or gold, which hold up better to biting pressure.
3. They’re custom-designed for a precise fit
   These restorations are crafted specifically for your tooth, improving comfort, function, and longevity. The seamless fit also helps keep bacteria out, lowering your risk of further decay.

In many cases, inlays and onlays serve as the perfect “middle ground” between a small filling and a full crown—offering protection without over-treatment.

A CONSERVATIVE OPTION WITH LONG-TERM BENEFITS

Inlays and onlays are an excellent choice for patients who want to restore strength and appearance to their smile while preserving as much of their natural tooth as possible.
