What are Dental Onlays?

Dental onlays, also known as partial crowns, are custom-made restorations that cover one or more cusps of a tooth. Unlike fillings, which are molded into place, onlays are fabricated in a dental lab and then bonded to the tooth. They are typically made from durable materials like porcelain, composite resin, or gold.

Benefits of Dental Onlays

The benefits of onlays include their ability to strengthen and stabilize a damaged tooth, a more precise fit compared to fillings, and better aesthetics as they can be matched to the natural tooth color. Onlays also preserve more of the natural tooth structure than crowns.

The Dental Onlay Procedure

The onlay procedure usually requires two visits. During the first visit, the dentist removes decay and makes an impression of the tooth, which is sent to a lab to fabricate the onlay. In the second visit, the onlay is bonded to the tooth. The process restores the tooth’s shape and function.

Caring for Your Dental Onlay

Care for a dental onlay involves regular oral hygiene practices, such as brushing twice a day and flossing. It’s important to avoid chewing hard foods that could damage the onlay. Regular dental check-ups are crucial for ensuring the onlay and the natural tooth remain in good condition.

Dental Onlays vs. Traditional Fillings and Crowns

Dental onlays offer a more conservative approach compared to crowns as they require less removal of the natural tooth structure. They are more durable and provide a better fit than traditional fillings, making them ideal for teeth with significant decay or damage that doesn’t warrant a full crown.

Dental onlays are a valuable option in restorative dentistry, offering a balance between conservation of tooth structure and restoration of function and aesthetics. They are a suitable choice for patients looking for a durable solution to tooth decay or damage that falls between a filling and a crown.

How long do dental onlays last?

Dental onlays can last for many years, often over a decade, with proper care and maintenance. Their longevity depends on factors such as the material used, the location of the onlay, and the patient’s oral hygiene and habits.

Are dental onlays noticeable?

Dental onlays can be made to match the color of the natural tooth, making them relatively unnoticeable. Porcelain onlays, in particular, offer excellent aesthetic results.

Can dental onlays be used for all teeth?

Dental onlays are typically used for back teeth where the chewing forces are greatest. They are suitable for restoring large cavities or damaged cusps but may not be recommended for front teeth or small cavities where a simple filling could suffice.
