A filling substance, commonly referred to as a dental filling, is a material used to restore the function, integrity, and morphology of a tooth that has been compromised by decay or damage. The primary purpose of a filling is to prevent further decay, restore the tooth’s structure, and restore normal chewing function. Fillings are a fundamental procedure in dentistry, helping to preserve natural teeth and avoid more extensive treatments like root canals or extractions.

Fillings are typically made from various materials, each with distinct properties and applications. Amalgam, a mixture of metals including silver, mercury, tin, and copper, was historically the most common filling material due to its durability and cost-effectiveness. However, concerns over mercury toxicity have led to increased use of alternative materials. Composite resins, made of plastic and fine glass particles, are popular for their aesthetic appeal, as they can be matched to the color of natural teeth. Other options include porcelain, gold, and glass ionomer, each offering different benefits in terms of strength, longevity, and appearance.

The choice of filling material depends on factors such as the location and extent of the decay, the patient’s oral health, aesthetic preferences, and budget. Fillings are applied during a routine dental procedure, where the decayed portion of the tooth is removed, and the filling material is placed and shaped to fit the cavity. Modern dental techniques often involve bonding agents to ensure a secure and long-lasting seal.

Regular dental check-ups help monitor the condition of fillings, as they may eventually wear down or develop gaps that could lead to new decay. Proper oral hygiene, including brushing, flossing, and avoiding hard or sticky foods, can extend the lifespan of fillings. Advances in dental materials and techniques continue to improve the effectiveness and comfort of filling procedures, making them a reliable solution for restoring damaged teeth.
