Dental tooth fillings are a way to repair a tooth that has been damaged by decay so that it can resume its usual function and shape without any pain. To fit a new filling, your dentist will remove any decayed tooth tissue  clean the cavity, and then fill the space with the material you’ve chosen for your filling. This prevents further decay and can strengthen the damaged tooth once more.

There are several materials used in dental tooth fillings Mi, each with their advantages and disadvantages.

Amalgam Fillings

Amalgam, or silver, fillings are very functional in that they are relatively inexpensive and are very resistant to wear, ensuring they can last a long time. The primary disadvantage of these fillings is that the amalgam, which consists of mercury and other metals such as copper, tin, zinc, or silver, takes on a dark silvery color. Against the white of your teeth, this can make the filling noticeable, particularly if it is used in your front teeth.

Gold Fillings

At the other end of the price scale, you have gold fillings. These are fillings that are made to order in a laboratory before your dentist fixes them in place, where they can last for more than 20 years. As a highly inert metal, gold fillings are very well tolerated by gum tissue, and their durability has meant that gold fillings are a popular choice.
However, as they need to be custom made before being fitted, it will take several appointments before you can receive your filling and the material cost of gold is significantly higher than amalgam. With the price of gold still very high, these fillings are likely to be the most expensive option.

Composite Resin Fillings

In contrast to amalgam and gold fillings, composite tooth fillings are designed to blend into the natural color of your teeth. Because of this, they are often the material of choice for fillings that are going to be easily visible, such as those in your front teeth. To fit the filling, the different materials that make up the plastic resin are mixed and inserted into the cavity directly to harden, instead of having the filling custom made.

These fillings typically last between 3 and 10 years, which is a shorter lifespan than the other materials discussed here, and they can become stained over time. However, they are much less expensive than the more durable alternatives, and their ability to blend into your teeth has made composite tooth fillings very popular.

Porcelain Fillings

Often called inlays or onlays, porcelain fillings are, like gold, made to order in a lab before they can be fixed. A porcelain restoration is typically used to reconstruct most of the tooth, instead of simply filling in a hollow at the core.

The advantage of these types of fillings is that, like composite tooth fillings, the color of the filling can be matched to the color of your teeth, making the inlay less noticeable. The porcelain is also resistant to staining, allowing it to keep its original color over long periods.

The downside is that, as with gold fillings, porcelain inlays need to be custom made, delaying their fitting, and the material cost is very high. Depending on the extent of the filling needed, porcelain inlays can match gold fillings in terms of cost, and this has limited their use.
