Primarily used in restorative treatments, dental fillings are ideal for patients who wish to repair moderate tooth fractures, a decaying tooth, or a damaged tooth surface. They can also even out tooth shells for better biting or chewing. Since dental fillings cover a damaged tooth, patients with sensitive teeth may also undertake the treatment.
Restorative dentists usually recommend dental fillings, because they can immediately put a stop to many oral concerns. However, many practices in Loughton that offer cosmetic dentistry also recommend the treatment, because of its assorted materials. Here are the four kinds of dental fillings.
Amalgam fillings are a traditional kind of tooth fillings that usually last for ten years. Made of tin, zinc, copper and mercury, amalgam fillings are ideal for back teeth because of their silver colour. Many patients prefer this dental filling because it is the least expensive type of restorative material. People who are allergic to mercury, however, should opt for other kinds.
Composite Resin Fillings
Made of plastic and fine glass, composite resin costs more than amalgam fillings, but lesser than cast gold. This kind of material comes in two types: Direct and Indirect. Direct fillings entail a bright blue light that hardens the material before application while indirect fillings require a laboratory mould. Composite fillings can bond directly to the tooth, which makes them stronger than amalgam.
Cast Gold Fillings
Cast gold fillings are more expensive than amalgam and composite. Mostly made of gold alloy, cast gold fillings are durable enough to withstand the pressure of chewing. They can last for fifteen years, depending on the patient’s oral habits. Cast gold does not corrode, but it requires at least two dental appointments. Patients with amalgam fillings should be wary of this procedure because of an oral discomfort called galvanic shock.
Commonly made of porcelain, ceramic fillings are ideal for inlays, onlays, crowns, veneers, implants and orthodontic brackets. These tooth-coloured fillings can last for more than seven years mainly because of its resistance to staining and abrasion. In order to receive a ceramic filling, the patient’s tooth may need alteration so that there will be more room for the extra bulk.
Before receiving a dental filling, it is important to determine the material that is right for your oral concern. Apart from ensuring its durability, this also prevents further oral problems.
