Types of Filling Are Available at London dental clinic
There are two main types of fillings; direct restorations which are placed immediately into a prepared cavity in just a single visit to the dentist. They include resin ionomers, glass ionomers, dental amalgam, and most composite (resin) fillings. The dentist prepares the tooth, places the filling and adjusts it during one appointment.
Indirect restorations will require you for two or more visits to the dentist. They include inlays, veneers, bridges with gold, on lays and crowns. On your first visit he will only prepare the tooth and will only make an image of the area, which needs the treatment. The image or the impression will than be sent to a dental laboratory, which will create the dental filling (restoration). Than on the next appointment, he will cement the filling onto the prepared tooth and will adjust it accordingly.
The Direct Restoration and the indirect restoration are than further classified;
Direct Restorations
Amalgam
This word “amalgam” when it is referred to as dental filling it means mixture of two or more metals in which the component is mercury. Dental amalgam is a mix of approximately 43 percent to 54 percent mercury with other metals like, including copper, silver and tin.
Glass Ionomer
These are materials, which are tooth-coloured and are made from the mixture of acrylic acids with fine glass powders, which may be used to fill the cavities, mostly those, which are on the root surfaces of the teeth
Resin Ionomer
They are also made from glass filler with acrylic acids and acrylic resin and are used to harden with their exposure to blue light. They are mostly used for the fillings on non-chewing surfaces and filling in baby teeth. They increase the durability because of their metal structure.
Indirect Restorations
Porcelain (ceramic)
The most common ones are like ceramic, porcelain and glass-like fillings and crowns. They are used in on lays, inlays, cosmetic veneers and the crowns.
Gold Alloys
They contain gold, copper and other metals, which result in strong, effective filling, bridge or crown. They have great durability and good resistance
