In the past, the most common type of dental filling was silver amalgam. Silver amalgams are malleable, safe to use in the mouth, and bond relatively well with the existing teeth. However, silver amalgams may be quite unsightly, especially if they are visible when you smile.
Silver amalgams are often grey in colour and do not match the surrounding teeth. While we usually think of silver as a beautiful, precious metal, in the world of dental fillings, it is unattractive. As such, porcelain fillings and crowns are becoming a more popular option. The exchange of silver fillings with a tooth coloured composite is a common cosmetic dentistry service in Barnsley.
Silver amalgams consist of a mixture of different types of metal. They may include metals such as silver, tin and copper. They may also include trace amounts of mercury. Dentists choose silver amalgam fillings because they are cost-effective, easy to work with and hard-wearing.
As such, it is often used in the back teeth, as it may withstand the constant grinding and chewing motions of the molars. One of the downsides of this type of filling is that it requires the removal of some teeth so that it anchors correctly.
Porcelain fillings are often tooth coloured and blend in well with the surrounding teeth. Porcelain fillings are highly resistant to staining. They are hard wearing, and usually have a lifespan of at least 15 years.
Porcelain fillings are not made of pure ceramics. It is a composite resin material with porcelain powder mixed in. It moulds into the tooth and binds well with the surrounding material. Due to how well it anchors into the tooth, it usually does not require as much tooth removal as silver amalgams.
Porcelain fillings are usually applied to the front teeth. However, many people request to use them in the molars for cosmetic reasons. It blends in and improves your smile.
Although silver is still widely used in filling cavities, there are times when porcelain is the better choice. This is definitely true in the world of cosmetic dentistry. Tooth coloured porcelain fillings simply look more natural and are more attractive than silver fillings.
