Dental fillings are used to replace missing tooth structure. Tooth structure may be missing due to dental decay or due to fractures or cracked teeth. Dental fillings can be placed using a product called composite resin which is good for replacing small areas of tooth loss. Alternatively, fillings can be made outside of the mouth with porcelain which ensures the best fit and strength possible and is good to replace larger areas of tooth loss. Both filling options we use are tooth coloured and in most cases look almost exactly like your natural tooth.
