Composite Resin Fillings — What Are They?

January 9, 2020

When the subject of dental fillings is considered you will have two options along with your dentist to go ahead with the procedure. You can consider amalgam fillings that are made from a mixture of metals or composite resin. Both types of fillings have many advantages as well as drawbacks and should be considered before going ahead with the procedure.

Let us consider the benefits and disadvantages you can face both types of fillings.

What Are Silver Amalgam Fillings?

Amalgam fillings are popularly known as silver fillings. The material used for the filling is a mixture of mercury, silver, tin, and copper. 50 percent of the material is made up of mercury which binds the metals together to form a strong and durable filling. Mercury becomes a stable compound when it is combined with other metals. This variety of dental filling is being used since 1895.

Amalgam fillings are being used for over a century and an affordable option. They are long-lasting and once filled in your mouth a visit to the dentist for replacement or repair is unnecessary for over a decade. Unfortunately, they also have their drawbacks because they are noticeable and cause metal allergies in some people.

What Are Composite Resin Fillings?

Composite resin fillings are developed from compounds of ceramic and plastic. Resin can mimic the natural appearance of the teeth making it possible for them to blend in right away. There are also popular as white fillings or tooth-colored fillings.

Composite resins or white fillings are aesthetically appealing but require a longer time to place and are not as durable as silver amalgam. They are made from glass and resin that can be used both as fillings and to repair any defects in the teeth. They are difficult to distinguish from natural teeth because of their tooth-colored appearance. The front teeth are the most popular recipients of composite resin fillings because people consider they need to have a natural appearance. The can be used on the molars as well after considering the location and the extent of the tooth decay.

Composite fillings are a mixture of acrylic resin and finely ground glasslike particles which combined produce a restoration of the tooth-colored variety. These can provide durability and resistance in small to mid-size restorations that just need to withstand moderate chewing pressure. Much of the tooth structure does not need to be removed making it possible for the dentist to place smaller fillings than with other varieties of material.

What Are the Benefits and Disadvantages of Composite Resin Fillings?

Composite resin fillings have an appearance that is similar to the natural teeth allowing them to blend into your mouth. The resin composite bonds to the surface of the tooth. The dentist does not have to use the drill to remove much enamel during the procedure.

Composite resin fillings are not as durable as amalgam fillings and will need to be replaced in 5 to 7 years. The process of placing the filling is involved and will require more time at the dentist’s office.

Are Composite Resin Fillings Suitable for Children?

Present-day children are more concerned about their appearance than their seniors were and do not favor amalgam fillings for cavities in their mouths. Resin filling for kids will be offered by dentists if requested to improve the aesthetic appearance of the child. However, parents will have to shell out a higher figure for the fillings with the knowledge that it would have been better for the child to have amalgam fillings in his or her mouth. Moreover, dental insurance companies do not offer coverage on composite resin fillings on the back molars where amalgam fillings are considered more durable. It may be a factor that parents should consider when dental fillings are needed by the children.

The advances made in modern dentistry along with the materials and techniques are increasingly offering ways to create more pleasing and naturally -looking smiles. Researchers have been continuing their efforts which have been ongoing for decades to develop materials that are aesthetically pleasing and are using ceramic and plastic compounds that can mimic the appearance of the natural teeth. People have taken them as a perfect alternative to having fillings of the natural variation in their mouth rather than consider metal fillings that are visible and are not pleasing to the eye.
