When getting a dental filling, you usually have two options: white filling and amalgam (silver) filling, not to mention other types. So, what is the difference between white and amalgam dental fillings, and which one should you choose? Follow us in this article as we present the differences between them and their most important advantages and disadvantages.
White Dental Filling
This type is considered one of the most commonly used dental fillings, as it can be used to treat many dental problems. Here is everything you want to know about it:
What is a white dental filling?
It is a type characterized by its color being very close to the color of the teeth, which is why it is called a white filling. It is a filling based on composite material.
Advantages of White Dental Filling
This type is characterized by a set of properties that make it the first choice for many, because:
- It does not cause pain like traditional dental fillings.
- Helps protect and strengthen the tooth structure.
- Adheres properly to the teeth.
- Does not cause severe sensitivity after placement.
- Available in different colors and shades that match the natural tooth color.
Disadvantages of White Dental Filling

- It is a procedure that requires some time to perform.
- High cost.
Amalgam (Silver) Dental Filling
It is the traditional filling, scientifically known as amalgam filling, and it consists of different metals, which is why it appears silver. It is made of mercury and silver, and it is the most common type of filling.
Advantages of Amalgam (Silver) Dental Filling
The most important features of the silver filling are:
- It lasts for a long time inside the mouth.
- It withstands the pressure exerted on it during chewing.
- It can be done in just one session.
- Low cost.
- Resistant to decay.
Disadvantages of Amalgam (Silver) Dental Filling

The Difference Between White and Black Dental Fillings
There are several factors we can compare when explaining the difference between white and amalgam dental fillings, and among these factors that you can consider are the following:
Type of material used
Amalgam filling relies on silver and mercury, and copper and tin may be added, while white filling is made of composite (resin).
Appearance
Due to the nature of the materials composing both fillings, the appearance of the teeth differs. Amalgam filling can be easily noticed, as it is clear due to its color, unlike white filling which is similar to the natural tooth color and therefore cannot be noticed. It can be designed to match the patient's tooth color.
Duration of stay inside the mouth
Amalgam filling is the most durable type of filling because it can last for a period of up to 10 to 15 years, and may last for longer periods, unlike white filling which may last on average up to 7 years, but it may last for a longer period.
Filling stability
Although amalgam filling can last longer, its stability inside the mouth is different, because it expands with heat and cold, making the molar more susceptible to fracture, while white filling is stable in size, thus reducing the chances of the molar fracturing.
Preparing for the procedure
Before placing either of them, the dentist will drill a hole in the tooth to remove the decayed parts and remove a part of the tooth to secure the filling.
In the case of amalgam filling, a large part of the tooth is removed to secure the filling and get rid of a large part of the tooth structure, especially since this filling cannot bond with the teeth. As for white filling, it bonds with the teeth, so only a small part is removed, including the affected part, which allows for the preservation of the natural molar and its structure.
Procedure Method
Decay is removed andDental fillings directly in the case of black fillings, while in the case of white fillings, after removing the decay, a layer of white filling is applied, then hardened with a laser, then another layer is applied, and so on, as it is applied in layers.
Based on these differences, you can choose what suits you from both types.
