A dental filling is something that is done to get cavities filled. Our dentists use preventive procedures like dental sealants in the fissures of teeth to prevent food deposit. Professional dentists at our office will numb the decayed tooth using a local anesthetic. The use of anesthetic will also numb gums and jaws around the teeth. Once the areas are anesthetized, our dentist will use a dental drill to remove the decay.

Once the decay is removed, the next step is the placement of filing. Well, there are several methods that our dentist use to insert the filling. However, it depends on the type of filling you are getting.

Various Types of Dental Fillings

Amalgam Filling
This type of fillings are made of a mixture of metals and have been used by dentists for more than 150 years. They comprise about 50% of mercury with tin copper, zinc and silver as other metals. Compared to other types, amalgam fillings are strong and durable. Amalgam fillings aren’t aesthetically pleasing, so they do not work for a tooth that is highly visible.

Composite Filling
Composite fillings are comprised of resin and plastic. It is placed into the cavity when it’s soft and then hardened with a bright blue light. It is quite popular because it can be matched to the color of the patient’s existing tooth. Composite fillings should be replaced every 5 years as they do not last long.

Ceramic Cavity Filling
A ceramic filling is a favorable option because they are both durable and aesthetically pleasing. They are more expensive than any other types because they are resistant to staining, abrasion and also match the tooth color. It can be as expensive as a gold filling.

Also known as Glass Ionomer fillings, resin fillings are generally for children whose teeth are still in a growing stage. Their span is less than 5 years but they contain fluoride which prevents the oral health from further decay. They are comparatively weaker than composite and more likely to wear and tear. They also don’t match the tooth color as composite resin.

On an average, dental filling last for 3-7 years, however, require annual regular checkups. So, if you come across discoloration, darkening or chipping under the filling, you must consult your dentist immediately. This reflects the need for replacement.
