Ceramic Fillings (Inlays/Onlays)
Ceramic inlays and onlays are precision-crafted restorations used to repair teeth with moderate to extensive decay or damage that exceeds what a standard filling can reliably restore. Sometimes referred to as indirect fillings, these restorations are fabricated in a dental laboratory from high-quality ceramic material and bonded into the tooth for a strong, long-lasting, and aesthetically superior result. An inlay fits within the cusps of the tooth, while an onlay extends over one or more cusps to provide broader coverage.
At Bensonhurst Dental Care, ceramic inlays and onlays are provided by Dr. Marina Rubinshtein as a conservative alternative to a full dental crown. When a tooth has too much damage for a composite filling but does not yet require the full coverage of a crown, an inlay or onlay preserves more of the healthy tooth structure while restoring strength and function. Dr. Marina's expertise in both restorative and cosmetic dentistry ensures that every inlay and onlay is not only structurally sound but visually seamless.
The process typically requires two appointments. At the first visit, the damaged or decayed portion of the tooth is removed and the tooth is prepared. A precise impression is taken and sent to the laboratory, where the inlay or onlay is custom fabricated to match the exact dimensions and shade of the tooth. A temporary restoration is placed to protect the tooth in the interim. At the second visit, the final restoration is tried in, adjusted for fit and bite, and permanently bonded into place.
Ceramic restorations offer exceptional durability, wear resistance, and biocompatibility. They do not expand or contract with temperature changes the way metal restorations can, and they maintain their color and polish over time. For patients who value both longevity and aesthetics in their dental care, ceramic inlays and onlays represent one of the finest options in modern restorative dentistry.
Frequently Asked Questions
What is the difference between an inlay and an onlay?
An inlay fits within the grooves and cusps of a tooth, similar to a filling but fabricated in a lab for greater precision and strength. An onlay is larger and extends over one or more of the cusps, providing more coverage for teeth with broader areas of damage. Both serve the same purpose of restoring the tooth without requiring a full crown.
How long do ceramic inlays and onlays last?
With proper care, ceramic inlays and onlays can last 15 years or longer. Their durability depends on the patient's oral hygiene, diet, and whether they have habits like grinding that could affect the restoration. A nightguard may be recommended for patients who clench or grind.
Why would I need an inlay or onlay instead of a filling?
When the area of decay or damage is too large for a composite filling to restore reliably, an inlay or onlay provides the additional strength and coverage needed. It is a more conservative option than a crown because it preserves more of the natural tooth structure.
Are ceramic restorations noticeable?
No. Ceramic inlays and onlays are custom shade-matched to the surrounding tooth, making them virtually invisible. The material mimics the translucency and color of natural enamel, producing a result that blends seamlessly.
