What are Dental Fillings?

Dental fillings are a common dental procedure that most people will have at some point in their lives. When teeth become decayed they are known as cavities and must be repaired by a dentist. Cavities are formed by bacteria on the teeth called plaque. Eating a large amount of sugar and not using proper dental care will increase the chances of plaque formation. Generally, the dentist will remove the decayed portion of the tooth, and will fill it back in with a particular material.

There are a number of different materials that the dentist may choose from. The four most common filling types are amalgam, gold, composite, and porcelain.

Amalgam fillings are comprised of a mixture of mercury, silver, copper and tin. They are most commonly referred to as the “silver” filling. Due to their color, amalgam fillings are used to fill in the back teeth. Amalgam is the least expensive type of filling, but is not desired by many people who wish to have a natural look.

Gold fillings consist of silver and copper and are created by using a mold of your tooth. The mold must be made in a dental lab and then cemented onto your tooth. Gold fillings are popular since they last a long time; however, they do cost more than other materials.

Composite fillings are known as plastic or white fillings. Getting this type of filling for your back teeth is not recommended since it is not very strong for biting down hard. Most people enjoy this type of filling because it is the same color as their teeth, and looks natural.

Porcelain fillings are used the most often by dentists because when combined with metal they can be made into a strong material, which is also the same color as a tooth. Porcelain fillings are more costly than most other types, but will last much longer.

In order to fill the cavity, your dentist will begin by giving you a freezing so that you will not feel any pain. He will then remove all of the decay, shape the hole, and fill it back in or cap it. The entire procedure will not take long and you will be permitted to leave the dental office when the process is through.

Many people are apprehensive about getting a cavity filled, because the word cavity often comes in conjunction with the word drill. Drills are used to remove some of the decay, but due to advanced technology are not as uncomfortable for the patient as they would have been in the past. Most patients experience very little discomfort. It is important that you feel comfortable with your family doctor and that they make you feel at ease throughout the entire process.
