A dental onlay is a type of dental restoration used to repair and restore a tooth that has a moderate amount of damage or decay. It is a conservative treatment option that covers a larger portion of the tooth than a dental filling but is less extensive than a dental crown. Onlays are custom-made restorations that fit onto the biting surface of a tooth and, in some cases, extend to cover one or more cusps.
Dental onlays can be used to address a range of dental issues, including moderate decay, large fillings, and fractures. They are suitable for restoring posterior teeth (molars and premolars) that experience significant biting forces.
Depending on the material used, onlays can provide a natural and aesthetically pleasing appearance. Porcelain onlays, in particular, can be color-matched to the surrounding teeth for a seamless blend.
The preparation process for a dental onlay involves removing the damaged or decayed portion of the tooth while preserving the healthy tooth structure. This is a more conservative approach compared to the preparation for a dental crown, which requires more extensive removal of tooth material.
Dental onlays are custom-made to fit the specific tooth and match the natural anatomy of the patient’s dentition. The customization ensures a precise fit and optimal function.

What are onlays in dentistry?
Onlays are dental restorations that are used to repair and restore the biting surface of a tooth. They are larger than dental inlays and can cover one or more cusps of a tooth.
What materials are used for onlays?
Two common materials for onlays are gold and porcelain. Gold onlays are made of a gold alloy, while porcelain onlays are crafted from dental ceramic.
What are the advantages of gold onlays?
Gold onlays are known for their durability and longevity. They are wear-resistant, biocompatible, and require minimal tooth structure removal during preparation.
What are the advantages of porcelain onlays?
Porcelain onlays provide a natural appearance, as they can be color-matched to the surrounding teeth. They are also biocompatible and can be an aesthetically pleasing option.
How is a gold onlay made and placed?
Gold onlays are typically created in a dental laboratory using a cast gold alloy. The onlay is custom-made to fit the prepared tooth, and it is then cemented onto the tooth during a subsequent appointment.
How is a porcelain onlay made and placed?
Porcelain onlays can be made using computer-aided design and manufacturing (CAD/CAM) technology or traditional dental laboratory techniques. The onlay is bonded to the tooth using dental cement.
Which is more aesthetically pleasing, gold or porcelain onlays?
Porcelain onlays are often preferred for their ability to closely mimic the natural appearance of teeth. They can be color-matched to blend seamlessly with the surrounding dentition.
Are there any disadvantages to gold onlays?
While gold onlays are durable, some people may find the appearance less appealing due to the metallic color. Additionally, gold may conduct temperature more than other materials.
Are there any disadvantages to porcelain onlays?
Porcelain onlays, while aesthetically pleasing, may not be as durable as gold onlays. They can be more prone to chipping or cracking, particularly in individuals with heavy biting forces.
How long do onlays typically last?
Both gold and porcelain onlays can last for many years with proper care and maintenance. Regular dental check-ups and good oral hygiene practices contribute to their longevity.
Is the preparation process different for gold and porcelain onlays?
The preparation process is similar for both types of onlays. The dentist will remove the damaged or decayed tooth structure, take impressions, and send them to a dental laboratory for fabrication.
Are onlays a suitable option for everyone?
Onlays can be a suitable option for individuals with moderate tooth damage or decay. Your dentist will assess your specific condition and recommend the most appropriate treatment.
It’s important to consult with your dentist to determine the best type of onlay for your individual needs, taking into consideration factors such as aesthetics, durability, and cost.
