Dental fillings are materials used to repair and restore teeth that have been damaged by decay or cavities. When tooth decay occurs, it creates holes or openings in the tooth structure, which can lead to further decay and infection if left untreated. Dental fillings are placed in these cavities to restore the tooth's shape, function, and strength, as well as to prevent further decay.
There are several types of dental fillings available, including:
-
Composite fillings: Also known as tooth-colored or white fillings, composite fillings are made of a mixture of plastic and fine glass particles. They can be closely matched to the color of the natural tooth, making them a popular choice for front teeth or visible areas of the mouth. Composite fillings bond directly to the tooth structure, providing excellent strength and durability.
-
Ceramic fillings: Ceramic fillings, also called porcelain fillings, are made of a high-strength dental ceramic material. They are tooth-colored and highly aesthetic, making them an excellent choice for front teeth or areas of the mouth where appearance is important. Ceramic fillings are also biocompatible and resistant to staining.
-
Glass ionomer fillings: These are made of a mixture of glass and acrylic materials. Glass ionomer fillings release fluoride, which can help prevent further decay and strengthen the surrounding tooth structure. They are often used for small cavities in areas of low chewing pressure or for filling baby teeth.
-
Gold fillings: Gold fillings are made of cast gold alloy and are extremely durable and long-lasting. They are well-tolerated by the gum tissues and are often used for large cavities in areas of the mouth where chewing forces are greatest.
The type of filling material used will depend on various factors, including the size and location of the cavity, the patient's oral health needs, and personal preferences. Your dentist will recommend the most appropriate filling material for your specific situation.
