The Different Types of Dental Fillings

When you have severe tooth decay, you should seek treatment immediately. The most common treatment method for tooth decay is a dental filling. Dental fillings restore the affected tooth to its normal shape and function and preserve its structure. The following blog explores the different types of dental fillings and how to ask a dentist which is best for you.

Amalgam fillings

Amalgam (silver) fillings are one of the most common dental fillings. Dental professionals have used them for over a century to repair tooth decay, particularly large cavities in one's molars and premolars. These fillings contain different metals, such as silver, tin, copper, and mercury. They are known for their strength and durability, lasting from ten to 15 years. However, the biggest drawback of this tooth-filling option is that their appearance sticks out from one's teeth, making them less aesthetically pleasing.

Composite fillings

Composite fillings (also known as tooth-colored or white fillings) contain a mixture of resin and glass or quartz particles. This type can be closely matched to the color of the patient's natural teeth, providing a more aesthetically pleasing option. In addition, this material bonds directly to the tooth structure, allowing for minimal removal of healthy tooth material. These fillings are versatile and can work on both front and back teeth. However, composite fillings may not be as durable as amalgam fillings and require more frequent replacement, particularly for large cavities.

Ceramic fillings

Ceramic or porcelain fillings contain a strong, tooth-colored material. They are known for their natural aesthetics and can blend seamlessly with the teeth. In addition, ceramic fillings are resistant to staining and offer long-lasting durability, lasting more than 15 years. This makes them an ideal choice for restoring cavities in visible areas of the mouth. However, ceramic fillings are expensive and may require multiple visits to the dentist for proper placement.

Glass ionomer fillings

Glass ionomer fillings are composed of acrylic and specific glass material. These fillings commonly fill cavities underneath the gum line and young children with cavities. Glass ionomers release fluoride, which can help protect the tooth from future tooth decay.

Unfortunately, this type of filling is weaker than composite resin and more prone to wear and fracture. Glass ionomer typically lasts five years or less. However, newer technology allows the material to last longer in certain areas.

Gold fillings

Gold fillings, also known as inlays or onlays, are composed of gold alloys. These fillings are durable and can last several decades because they do not corrode. These fillings integrate into the patient's gum tissues and offer an effective, long-term solution.

However, placing gold fillings requires more than one visit to the dentist since they are fabricated in an off-site dental laboratory. Gold fillings are also more expensive than other dental fillings, and some patients may not prefer them for more visible areas of the mouth.
