Composite Resin vs. Amalgam

First of all, before we pit composite resin vs. amalgam fillings, it’s important to understand that both variations serve the same purpose. Both services aim to fill the damage done by tooth decay. They are dental fillings after all so it’s expected that both of them have the same function. This whole comparison will go over the advantages and disadvantages that one has that other doesn’t. So, let’s start with the former, composite resin.

Composite Resin

When it comes to dental fillings, a composite resin one has to involve appearance. A composite resin filling is made out of a combination of ceramic and plastic. This gives it the advantage of being able to blend very well with the other teeth. Because of this, a composite resin filling is much more viable when placed at the front teeth. In addition, since they’re made out of flexible materials, a composite resin filling is capable of being shaped into any form of the teeth. This gives it the advantage of versatility as it is capable of fixing different kinds of issues regarding tooth decay.

So, in summary, here are the advantages of using a composite resin filling:


  • Appearance – blends well with other teeth due to their color that gives them a natural look.
  • Versatility – it’s much easier to be shaped and molded, hence it’s able to be placed in different forms of damage.


  • A composite resin filling doesn’t also discolor the teeth it’s placed on.

As for its disadvantages, here are some to keep in mind of:


  • Durability – when compared to amalgam fillings, a composite resin filling falls flat in terms of durability. It still falls victim to teeth grinding and has the tendency to chip if put under enough pressure.
  • Longevity – a composite resin’s natural composition doesn’t have much in terms of longevity. It wears down faster than amalgam fillings and are susceptible to damage.
  • Drier Mouth – a composite resin filling is harder to shape or apply if the area around it is not dry enough. This gives the dentist a harder time to apply the material.
  • Price – when it comes to pricing, composite resin fillings are much more expensive. Keep this in mind the next time you’re trying to save money on the service.


Amalgam Fillings

Amalgam fillings have a longer track record than composite resin. It has been used by dental practitioners for more than a century. So, one can only understand that it’s pretty popular among the masses.

As for its material, amalgam filling is made out of an amalgamation of tin, silver, copper, and mercury. This gives amalgam fillings a metallic look in their finished state. Of course, this doesn’t bode well in terms of appearance. Everyone who takes a good look at your teeth will surely notice the metal fillings placed in it.

Here are some of its advantages:


  • Price – amalgam fillings are pretty much one of the more cheaper dental fillings to date. It doesn’t ask for much and it’s effective in its function as a filling.

  • Track Record – amalgam fillings have picked up a long history of successful track records when compared to composite fillings. Most people stand by it and say that it’s worth paying the money for.
  • Longevity – amalgam fillings are capable of lasting for 20+ years. It’s hardy structure and material allows it this much time.


Here are some of its disadvantages:


  • Limited Shape – composite resin fillings are much easier to mold and shape. Amalgam fillings, on the other hand, only have a limited shape to follow. This doesn’t allow it to fit every damage that’s caused by tooth decay.
  • Aesthetics – as mentioned above, amalgam fillings aren’t the best in the looks department. Don’t expect to come into the service with hopes that it’s able to blend well with the other teeth. It won’t.
