Inlays & Onlays

Inlays and Onlays

Dentistry has been greatly expanding in technological advances over the years, but one of the most significant may have been in the mid-1800s with the introduction of restorative methods known as inlays and onlays.  Originally cast from metals like other restorative procedures were during this period of time, these restorations were a way to restore the functionality of a tooth without having to remove a significant amount of healthy tooth before placing a crown. At The Center City Dental Office of Dr. Renee Yurovsky, we offer porcelain inlays and onlays to patients who have experienced trauma too extensive to fix with a composite filling alone, in order to preserve the dental structure. 

When it comes to repairing a damaged or chipped tooth, there are various factors which need to be taken into consideration for treatment options. From the size of the fracture to the state of the adjacent healthy teeth, you need an expert cosmetic dentist to diagnose the problem and restore your smile back to its glory, and Dr. Yurovsky is your trusted provider.

When more than half of a tooth is damaged to the point where it, can no longer support a filling, the use of an inlay or onlay repair may become necessary. More conservative than a crown, these two restorative methods can rebuild a damaged tooth structure, giving it back to its original functionality.  Inlays and Onlays are known as indirect fillings because they are both made in a laboratory and then cemented to the surface of the tooth during your second visit to our office.

Inlays and Onlays are made of porcelain, gold, or composite resins which are bonded directly to the tooth’s structure.  These materials are stronger in composition than the traditional unsightly metal fillings, and ultimately help to prevent any further decay or damage to the tooth.


Both of these restoration processes are similar in function, the difference is the fact that they repair different parts of the tooth.  If a tooth has extensive damage to its surface, the use of an onlay would be best suited to fix the problem.  An onlay is placed on one or more of the cusps of the tooth, or, in a more severe cases, on the entire surface.  Onlays are generally more durable in structure, and last for a longer period of time than inlays do.


Inlays are repairs used in dental situations where a Dental Filling cannot properly fix the damaged area.  However, where there is less damage to the structure, a Crown or onlay would be more appropriate.  An inlay basically fills the spaces in between the cusps of the center of the tooth.  

The Procedure

The procedure will begin with the removal of the damaged area of the tooth by Dr. Yurovsky.  From this point, she will take an impression of your tooth, which will be sent over to the dental lab, where a restored structure for the tooth will then be constructed.  Once the inlay or onlay has been properly constructed, and is fitted in order to best match the surface of your tooth, Dr. Yurovsky will bond the well-fitted onlay or inlay to your tooth using a strong resin.
