Dental Fillings

Once the tooth cavities are detected, they should be treated as soon as possible. The treatment for tooth cavities is done by filling. Filling is an implementation to regain the natural shape of tooth before decaying, through which the tooth cavity is filled with suitable materials to restore its function and aesthetics after the decay in the tooth is cleared away. While the filling material is being chosen, the position and function of the tooth are taken into account. Since the chewing function of the teeth is basically performed in molar teeth zone, these teeth are exposed to more pressure. For this reason, more durable filling material needs to be used when molar teeth are filled. For the incisor teeth, on the other hand, a filling material compatible with the natural color of teeth is preferred, so that the filling cannot be noticed as much as possible.


The amalgam dental fillings are also known as silver fillings. Amalgam is obtained by mixing the silver, tin, and copper alloy with mercury. The amalgam fillings are being used for approximately 150 years.

Advantages of the Amalgam Dental Fillings

They are the longest lasting and cheapest filling material.

Their implementation takes less time compared to the other filling materials.

Disadvantages of the Amalgam Dental Fillings

They are not aesthetically appealing.

Some might be allergic to the mercury inside.

There are debates on the mercury inside the amalgam dental fillings. However, since the mercury combines with the other metals inside, its chemical structure changes and it becomes harmless.

Points to Take into Consideration in Amalgam Dental Fillings

Since it takes approximately 2 hours for the amalgam filling to harden, eating should be avoided during the first 2 hours after filling. If something is eaten within this period, the filling may break due to the force it is exposed since it is not hardened enough yet. A corrosion layer forms on the amalgam in the course of time. In order to prevent this, the amalgam has to be waxed. However, the waxing operation can be performed 24 hours after filling. In case there are too many amalgam fillings in the mouth, sensitivity may occur due to electrification when there is a metal such asfork, inside the mouth. If it is certain that the sensitivity occurs due to this metal, the filling material may be replaced with a non-metal one.


Since the composite dental fillings have the same color as the tooth, they are also called white dental fillings. Although they could be used for only the incisor teeth when they first developed, their resistance against the chewing force has been increased and the wearing rates have been decreased by the time, and they can be used in the rear molar teeth now.

Advantages of the Composite Dental Fillings

The greatest advantage of the composite dental fillings is that they are aesthetically appealing.

They can be waxed right after the filling is done.

They can be used not only for restoring the tooth decays but also for cosmetic operations by changing the shape and color of the teeth.

Disadvantages of the Composite Dental Fillings

The composite dental fillings are applied layer by layer, and they are hardened with a special light. Therefore, their preparation takes more time and it is harder compared to the amalgam fillings.

Their price is a little bit higher than the amalgam fillings.

Although the composite dental fillings have been made quite durable recently, they are not as strong as the amalgam dental fillings.

A color change may be observed on teeth in long term.

Points to Be Considered

Being careful while biting with wide fillings will prolong the life of the filling.

Although the composite fillings are waxed well, color change may be seen in the course of time due to food and drinks.

Like the amalgam fillings, there is no limitation such as not eating during the first two hours after filling.

For the teeth that are restored due to abrasion, hard toothbrushes should not be used and the  attention should be paid to the brushing method.
