Amalgam Fillings

What are Fillings?

Fillings are used to fill holes (cavities) that have formed, usually as a result of decay or tooth wear. Dental decay is caused by plaque acids that gradually dissolve away the enamel and dentine of the tooth. Decay damages your teeth and may lead to the tooth needing to be filled or even taken out

How are they applied?

First of all of the decay is carefully removed from the tooth. Then the area is washed clear of debris and then dried. A bonding agent is then applied. Amalgam filling material is then packed into the hole, resulting in a strong and long lasting repair. Finally the top of the filling is shaped to match the bite surfaces of the teeth.

What are fillings made of?

Dental amalgam is a dental filling material used to fill cavities in teeth caused by decay, because of its appearance these are sometimes referred to as silver fillings. Dental amalgam is made up of a mixture of metals including silver, copper and tin and liquid mercury.

Although there is mercury in dental amalgam, once it is combined with the other materials in the amalgam filling its chemical nature is changed rendering it harmless.

Research into the safety of dental amalgam has been carried out for over a century and to date, no trustworthy controlled studies have found a connection between amalgam fillings and any medical problems.

Whilst composite (white or tooth coloured) fillings are becoming more popular, amalgam fillings represent the most durable and long-lasting form of filling available.

Can fillings be prevented?

The best way to prevent dental decay is to brush your teeth twice a day with a fluoride toothpaste, avoid surgery and acidic foods and drinks and visit your dentist for regular oral health checks.

If you have any concerns about the fillings you already have, or ones are considering changing to white fillings, please discuss the options with one of the dentists, they will be able to advise you on the best treatment for your individual needs.
