Dental fillings are materials used to fill in cavities and restore damaged teeth. When tooth decay erodes a part of a tooth, the dentist removes the decayed portion and fills the hole with a filling material. The process can be performed on both primary and permanent teeth.

How do dental fillings work?

Dental fillings help to restore the tooth’s normal shape, appearance, and function. It can also prevent further decay and damage to the tooth. The decayed part of the tooth is removed, and the filling material is then placed to cover the hole.

What materials are used for dental fillings?

There are several types of filling materials available, and the type of material used is dependent on the extent of decay, location, and personal preference. Common materials include amalgam, composite resin, and porcelain. Amalgam fillings are made from a mixture of metals, including silver, tin, and copper. Composite resin fillings are made of a plastic and ceramic compound and match the natural tooth color. Porcelain fillings are made of a durable, natural-looking material that is both stain and wear-resistant.

What should I expect during the process?

After your dentist has removed the decayed portion of the tooth, they will clean the area and prep it for the filling. The filling material is inserted in layers and cured with a special light. You may feel some sensitivity after the procedure which is normal and should go away after a few days.


In summary, dental fillings are a common procedure used to restore teeth and prevent further damage. There are several materials available, and your dentist will recommend the best type for your needs.
