Inlays and Onlays: A Middle Ground Between Fillings and Crowns

When it comes to restoring a damaged or decayed tooth, the proper treatment depends on the extent of the problem. Fillings are ideal for small areas of decay, while crowns are used when a tooth requires full coverage. But what about cases that fall somewhere in between? This is where inlays and onlays offer a valuable middle ground. These indirect restorations provide a durable, aesthetic, and conservative alternative for patients who need more than a filling but not a full crown.
As a Dentist in Chaska, I often recommend inlays and onlays to patients seeking a long-lasting, functional solution that protects the tooth without excessive removal of healthy structure. At Chaska Family Dental, we believe in selecting the most appropriate treatment for each individual, rather than defaulting to the most common option. Inlays and onlays preserve more of the natural tooth, are less invasive than crowns, and deliver excellent results for the correct type of restoration.
This article will explain how inlays and onlays work, when they are used, and why they may be the right solution for preserving your smile and supporting long-term oral health.
Inlays and onlays are indirect dental restorations made from porcelain, composite resin, or gold. They are custom-fabricated in a dental laboratory based on precise impressions or digital scans of your tooth. Once created, they are bonded securely into place.
Unlike fillings, which are applied directly into the cavity and shaped in the mouth, inlays and onlays are created outside the mouth and bonded into place with high precision. This makes them ideal for areas that require strong reinforcement or where cosmetic results are crucial.
One patient in our Chaska office had an old silver filling that repeatedly failed. Rather than place another filling or crown, we recommended a porcelain onlay. It matched her tooth perfectly and restored strength without unnecessary drilling.
Inlays and onlays offer several distinct advantages over traditional fillings or crowns.
For patients with large areas of decay but still enough healthy tooth to avoid a crown, inlays and onlays provide the best of both worlds. A Dentist Chaska patients rely on will evaluate each case carefully to determine if this middle option is most appropriate.
The decision to use an inlay or onlay instead of a filling or crown depends on several factors:
For example, we recently treated a patient who cracked the edge of a molar while chewing ice. A full crown would have required removal of healthy enamel, but an onlay restored the function and appearance without unnecessary tooth reduction.
In most cases, receiving an inlay or onlay takes two visits.
The process is similar to receiving a crown, but it is often more conservative and less invasive. Thanks to modern materials and digital techniques, the result is a precise, functional, and long-lasting restoration.
At our office, we use digital scanning technology that eliminates the need for messy impression materials and improves accuracy. This allows us to deliver a highly personalized fit for every patient.
Inlays and onlays are designed to last many years with proper care. The longevity of these restorations often exceeds that of large fillings, and with good hygiene, they may last as long as crowns.
To care for your inlay or onlay:
With regular care, patients enjoy decades of function from well-placed inlays and onlays. A Dentist in Chaska will monitor the health of the restoration during routine checkups and make recommendations as needed.
How long do inlays and onlays last?
With proper care, inlays and onlays can last 10 to 30 years, depending on the material used and oral hygiene habits.
Are inlays and onlays better than fillings?
They offer better strength and durability for larger restorations, especially on back teeth. Fillings are still appropriate for small cavities.
Do inlays and onlays hurt?
The procedure is done under local anesthesia, and patients typically report little to no discomfort during or after the treatment.
Can an inlay or onlay fall out?
Although uncommon, this can occur if the cement breaks down or the tooth structure weakens. Regular dental visits help prevent this.
Does insurance cover inlays and onlays?
Many dental insurance plans offer partial coverage, particularly when a restoration is necessary for functional reasons. Our team can help check your benefits.
