The Unparalleled Benefits Of Inlays And Onlays Over Amalgam Fillings

August 5, 2020 - By Bruce Michaelson

There are a lot of fundamental changes that have come to be in the field of reconstructive dentistry. Numerous treatment options allow patients to get top-notch services with ease. 

Dental clinics have more to offer than the regular metallic filling and unattractive tooth repair work. 

Inlays and Onlays are new-age dental products used to repair damaged and decayed teeth. In this process, natural tooth-colored material is shaped and fitted over the damaged teeth in such a way that it blends with your original set of teeth. 

They perform the same function as traditional fillings but with an updated look. The main difference between amalgam fillings and inlays are in manufacturing. Inlays are made from products that are more durable, cosmetically appealing, and it is the better choice for the health of your teeth.


Inlays and Onlays

There are minor differences between inlays and onlays. Both are dental products used to repair mildly or moderately damaged teeth due to decay, chipping, or shallow fractures. 

The main difference between the two is that dental inlays are fitted inside the top edges of the tooth. However, an onlay is an extensive product, which extends over the cusps of the treated tooth. 

These dental products are a popular alternative and have started replacing traditional fillings.

Inlays and onlays are the preferred choices of treatment as they are cosmetically pleasant and practically durable in comparison to amalgam fillings. They are made from tooth-colored porcelain or resin and are made specifically to fit your teeth. They maintain the strength of the teeth and protect against further damage. 



The fitting is completed within the first three sessions. In the first appointment, the damaged tooth is treated, and a minimum amount of tooth decay is removed to make the tooth impression. The impression is used to ensure that the custom made inlay or only fits perfectly into the cavity or on the tooth. 

The dentist will mostly give you a temporary filling to protect the teeth while the permanent inlay or onlay is made. This is then fitted onto the tooth using a strong dental adhesive. The result is natural and healthy-looking teeth. The best part is that inlays or onlays can last up to 30 years!


Difference Between Inlays, Onlays, And Fillings

 The main differences between inlays, onlays, and fillings include: 

  • Fillings are made from amalgam or composite material, whereas inlays and onlays are made from porcelain or resin. 
  • The filling is fitted immediately after the tooth decay is treated or removed, whereas inlays and onlays require more time for the fitting process. 
  • Porcelain or resin inlays and onlays match the color of the teeth. It is more durable and can withstand the pressure of constant chewing. On the other hand, amalgam fillings are comparatively weaker. 
  • The fillings have to be replaced more frequently and are still prone to shrink or become loose with time.  
  • Only fewer amounts of the natural tooth are drilled while fitting inlays and onlays. This ensures that the tooth is strong and resilient.
