Composite and glass-ionomer fillings are popular choices for patients seeking a natural appearance. Composite resins are made from a mixture of plastic and fine glass particles. They are designed to match the shade of your natural teeth, making them nearly invisible in the mouth. These materials bond chemically to the tooth structure, providing strength and support to the remaining enamel.
Glass-ionomer cements are another tooth-coloured option, often used for fillings near the gum line or in baby teeth. A significant benefit of glass-ionomers is that they release fluoride over time, which can help protect the tooth from further decay. While they may not be as hard-wearing as composite resins, they are very useful in specific clinical situations where fluoride release is a priority.
Both materials are applied in a similar way. The dentist prepares the tooth, applies the material in layers, and uses a special curing light to harden it. Because these materials bond to the tooth, the dentist can often preserve more of the natural tooth structure compared to older types of fillings. This makes them a cornerstone of modern, conservative dental practice.
Your dentist will recommend the most suitable material based on the location of the cavity and the amount of pressure the tooth receives during chewing. Maintaining these restorations requires regular brushing and professional cleanings. If you have concerns about the appearance of your teeth, discuss these tooth-coloured options with a registered dentist.
