Tooth-coloured fillings can offer a durable, aesthetically pleasing treatment for cavities and tooth decay. This common dental treatment involves the use of tooth-coloured resin material to fill cavities and crevices to give strength, stability, and natural-looking results. Tooth-coloured fillings have come a long way since traditional, mercury-based fillings were used in dentistry years ago, and they can provide an effective solution for patients of any age.
