What Are The Differences Between Inlays And Onlays?

Inlays and onlays are restorative dental treatments that can use to restore teeth. Each type of restoration is made of different materials, but they both have the same purpose: to improve the strength and appearance of a patient’s teeth.

What Is An Onlays?

An Onlays is a more complex dental restoration to replace a missing tooth. The main difference between an inlay and an onlays is that it only covers part of the surrounding teeth, while an inlay only covers part of a tooth.

The material used to make an onlays can vary depending on your specific needs. Some common materials include porcelain or gold alloys (gold-colored). There are advantages and disadvantages associated with each type of material; for example:

  • Porcelain may be less expensive than gold alloy. Still, it will only last for a short time because it tends to chip easily when hit against another object, like food or drink utensils, during eating/drinking activities.* Gold alloy has been shown in studies done by dentists around the world as being more durable than porcelain when exposed to daily wear-and-tear from eating/drinking habits over time due at least partially because it contains no ceramic components which would otherwise wear down quickly after repeated impact damage from chewing food items throughout days/weeks/months etc.

What Is An Inlay?

Inlays are a type of dental restoration used to repair teeth that have been damaged, for example, by decay or erosion. Inlays are made from porcelain, composite resin, or gold and placed in the grooves or channels on the outer surface of your tooth (the crown).

Inlays can also be used as an alternative to crowns if you have quite healthy teeth but want to improve their appearance. They’re ideal for restoring broken-down teeth as they don’t require any preparation like crowns; this means there’s less chance of damaging healthy tissue during treatment!

The Difference Between Onlays and Inlays.

A dental inlay is a restoration placed into a damaged tooth’s interior. An onlays is similar to an inlay but covers more surface area and fills in a damaged tooth.

Inlays and onlays repair teeth damaged by decay or trauma, respectively. The main difference between these two types of restorations lies in how much tooth structure they require before placement: Inlays require minimal preparation. In contrast, onlays require more extensive removal (usually around 1/2 mm).

Inlays & Onlays Are Similar in That They Are Restorative Dental Treatments.

Inlays and onlays are similar in that they are restorative dental treatments. They are used to restore teeth damaged by decay or injury, such as a cracked tooth or broken filling. Both inlays and onlays are made of porcelain or composite (a tooth-colored material) and placed inside or outside your natural tooth, depending on your needs.

Inlays can be used when there is not enough room for a crown, but you still need a stronger bite surface than what can be achieved with fillings alone. An inlay will provide better protection against further damage than an ordinary filling because it covers more of the biting surface area of your teeth. On the other hand, if you want to improve the appearance of your smile without altering its function too much–for example, if one side has been chipped off entirely then onlays may be preferable since it won’t change how hard it is for you bite down properly while also covering up any gaps left behind after removing part of your enamel layer while drilling out excess decay buildup within crevices between gums/tooth root surfaces themselves.”


Inlays and onlays are restorative dental treatments that can repair teeth damage. An inlay is a thin piece of material (usually porcelain) placed inside the tooth, while an onlays are placed on top. The difference between these two types of treatment is not in what they do but in how they are placed into your mouth.


1.What is an Inlay? 

A person who has an inlay has a dental filling inserted into the tooth. It is usually placed in the cavity or back of the tooth. This procedure differs from an only, similar to a filling, but it’s placed on top of the tooth instead of inside it.

2. What is an Onlay? 

An onlay is a procedure where a dentist uses a special type of resin to cover the decay removed by root canal treatment. The resin helps to fill in gaps left behind after root canal treatment so that no open spaces are left in your mouth. 

3. What are the differences between Inlays and Onlays? 

Inlays and onlays are both dental fillings used in place of missing teeth. Still, they each have unique advantages and disadvantages compared with other types of fillings like crowns, bridges, or dentures (partial dentures).
