A filling is a way to restore a tooth damaged by decay back to its normal function and shape. By closing off spaces where bacteria can enter, a filling also helps prevent further decay. Materials used for fillings include gold, porcelain, composite resin (tooth-colored fillings), and amalgam (an alloy of mercury, silver, copper, tin, and sometimes zinc). The choice of material often depends on the location of the tooth, the extent of decay, and personal preference. Composite fillings are popular for their natural look, while gold and amalgam offer exceptional durability. A properly placed filling can last for many years, protecting the tooth and restoring comfortable function. Regular check-ups are essential to ensure fillings remain secure and effective over time.

What are Tooth-coloured Fillings?

Tooth-colored fillings, also known as composite fillings, are a modern alternative to traditional silver-mercury fillings. These fillings are stronger, more aesthetically pleasing, and offer longer-lasting results. Composite fillings are commonly used to treat cavities, chipped or broken teeth, and other types of dental damage. The material is applied in layers, with each layer hardened using a special light. Once the filling is in place, it is shaped and polished to seamlessly blend with the natural teeth. Composite fillings are suitable for both front (anterior) and back (posterior) teeth restoration.

When Do You Need Tooth Filling?

When bacteria first attack a tooth, it doesn't immediately reach the pulp. Instead, it starts in the outer layer (enamel), then moves to the second layer (dentin), and eventually reaches the pulp. The purpose of a tooth filling is to halt the progression of the cavity and prevent the decay from reaching the pulp. Once the decay infects the pulp, a filling is no longer effective, and the tooth will require a root canal treatment.
