Amalgam fillings

Amalgam fillings are a well-established and inexpensive way to repair damage to the tooth structure. They offer a highly effective way to restore the structure and functionality of a tooth, particularly the hardworking back teeth. This type of dental filling has been used to fill cavities for over 180 years, so it has improved oral health in millions of mouths. 

Having a filling is an extremely common procedure

Around 8 million cavities are treated with dental amalgam fillings each year in the UK and most of us, at some point in our lives, will have a cavity that needs attention. Amalgam fillings are the traditional choice, made from a combination of metals including silver, tin and copper, and elemental mercury. Although the inclusion of mercury as a filling material has attracted some controversy, a number of scientific studies have concluded that exposure to mercury in fillings is not linked to any adverse health effects. 

However, an alternative to these dental fillings would be used for those patients who have an allergy to any of the metals within the silver filling as well as children and for women who require treatment while pregnant or breastfeeding. 

Benefits

Amalgam fillings have several advantages over those made from composite resins.

  • Extremely hard wearing and can last for around 15 years or even longer in a well-maintained mouth 
  • Quicker to place than dental fillings made from composite resins  
  • Less expensive than alternative restorative methods 

Treatment steps

Treating cavities with silver dental fillings is a well-established practice. The treatment is as follows. 

  • The area to be treated is numbed with a local anaesthetic and the decayed part of the tooth removed with special dental tools. 
  • A base or liner may be placed in the tooth to prevent sensitivity following the procedure. 
  • The amalgam is mixed and then placed in the tooth. It is tightly compacted to ensure every part of the cavity is filled. 
  • The amalgam is then shaped to resemble the tooth and, if necessary, it is smoothed down so it feels comfortable. 

Aftercare

If looked after properly, silver dental fillings are very durable and are particularly suitable for permanent teeth that are subjected to lots of wear and tear, such as those at the back of the mouth. More discreet, white composite fillings can be used to treat decayed teeth but these tooth coloured alternatives are usually more expensive and can be less durable.

White dental fillings

Fed up with your shadowed smile? With the new generation of cosmetic tooth-coloured fillings, you could avoid amalgam fillings altogether for a smile that looks fresh and natural. At Newtown Dental Centre, white composite fillings are one of the most cost-effective and popular cosmetic dental treatments around. As well as blending with the surrounding tooth colour, so as to be virtually unnoticeable when you speak or laugh, white composite fillings often require less drilling than silver amalgam fillings.
