Dental fillings are materials used to repair teeth that have been damaged by decay or cavities. They help restore the function and structure of a tooth that has been affected by decay.

Here are some details about dental fillings:

Types of Fillings:

1. Amalgam Fillings: Made of a combination of metals, including silver, mercury, tin, and copper. They are strong and durable but more noticeable due to their silver color.

2. Composite Fillings: These are made of a mixture of glass or quartz filler within a resin medium. They can be matched to the color of the natural tooth, making them less noticeable but may not be as durable as amalgam fillings.

3. Gold Fillings: Made of gold alloy, these fillings are strong, durable, and well-tolerated by gum tissues. However, they are more expensive and require multiple visits to the dentist.

4. Ceramic Fillings: Made of porcelain, these fillings are tooth-colored and highly resistant to staining. They are also a more expensive option.

Procedure:

• Preparation: The dentist will first remove the decayed portion of the tooth and clean the affected area.

• Filling Placement: The chosen filling material is placed into the cleaned-out cavity and shaped to match the natural tooth structure.

• Bonding: Some fillings, like composite fillings, require a special light to harden the material and bond it to the tooth.

Considerations:

• Durability: Amalgam fillings are known for their durability and ability to withstand chewing forces. Composite fillings, while less durable, can be more aesthetically pleasing.

• Allergies: Some individuals may be allergic to certain filling materials, such as metals used in amalgam fillings or components in composite fillings.

• Cost: The cost of fillings can vary depending on the type of material used. Amalgam fillings are usually more affordable than gold or ceramic fillings.

Care and Maintenance:

• Regular oral hygiene practices, including brushing and flossing, help maintain dental fillings.

• Routine dental check-ups are essential to monitor the condition of fillings and address any issues early on.
