Has the dentist suggested cavity filling for your dental issue? Are you looking for how they work? Here’s all you need to know about the fillings:

About Cavity Filling

The dentist suggests filling for cavities in your mouth. People have several misconceptions related to fillings. Some people believe that it’s a disruptive process but that’s not true. It’s not a big deal to get fillings and you should not be afraid about the procedure.

What They Do?

Cavity is nothing but a hole left behind due to cavity. The cavity contains bacteria which can spread if left without treatment. During the filling procedure, the dentist will clean the cavity with a drill followed by filling the cavity. Removing the decay will prevent further damage, but for the damage that has already been done, filling comes into the picture.

Fillings are made to match the shape of the surrounding tooth. They help restoring the health of the tooth and even match your tooth’s color.

How Dentists Insert Them?

First the dentist will administer local anesthetic that will numb the cheek, tooth, and gums. Then he will use a dental drill for removing the decay followed by filling it.

Composite Resin

These are one of the most commonly used fillings as they match with the color of the teeth. They are durable and may last up to 10-15 years with a good oral care routine. It’s in the form of paste and acquires the shape of the cavity when inserted inside the tooth. It’s filled in layers and shaped followed by using a UV light to harden it.

Amalgam

It’s a mixture of several metals such as tin, mercury, and silver. These are the traditional metal looking fillings. They are comparatively less expensive, long lasting, and easy to place than composite fillings. However, they lack the natural look.

Why they’re Important?

When the tooth decays and results in a cavity, it can expose the nerves and also affect the tooth’s structural integrity or become infected. Thus, it is important to get the fillings after removing the cavity.
