Fillings

The bacteria in plaque produce acids that erode tooth enamel, eventually creating a hole, or cavity, in the tooth surface. Left untreated, this decay can spread to the interior of the tooth and might lead to the need for a crown, a root canal, or even extraction. When caught early, your dentist can treat your cavity conservatively by restoring your tooth's function and appearance with a filling.

What kind of filling do you need? Your choice of restoration will depend on the location of the cavity and how much of the tooth structure is affected.

Direct Fillings

For most small to moderate cavities, direct fillings can be bonded to the tooth immediately after removing decay. Composite resin, dental amalgam, and glass ionomer fillings are typically used for this type of single-visit restoration.

Indirect Fillings

An indirect filling is the right choice for molars and premolars with larger areas of decay or damage. Indirect fillings fit more securely, last longer than direct fillings, and can even strengthen the remaining tooth structure. An inlay fills the tooth surface inside the cusps, while an onlay typically covers the center of the tooth and one or more cusps.

Filling Options

• Composite Resin: Color-matched to blend with natural enamel. Popular for front teeth. Preserves more tooth structure.
• Dental Amalgam: Very durable and cost-effective. Often the filling of choice for biting surfaces.
• Glass Ionomer: Bonds to the tooth and releases fluoride over time. Best for baby teeth, gum line cavities, and temporary fillings.
• Gold: Extremely durable, lasting 20 years or more. More expensive but long-lasting.
• Porcelain: Most natural-looking. Color-matched and translucent, resistant to staining and cracking.

Discuss these options with your dentist to discover which filling is best suited to restore and protect your healthy, attractive smile.
