“Silver amalgam” is a dental filling material which used to fill the tooth cavities or oral pits. It is in use as a dental filling material for over 150+ years. Whereas “Dental amalgam” is a mixture of liquid containing mercury and powdered alloy consisting of silver, tin and copper. Also, this Mercury amalgam reacts with the silver, copper and tin mixture and the binding of which forms an amalgam mixture. Should Dental Amalgam be replaced with other restorations?
In the last few decades concerns over potential toxicity of silver amalgam has made dentist to look out for other options. Newer materials like composites, polymers and ceramics are gaining popularity.
Is Dental Amalgam Safe For Health?
Dental amalgam fillings may release small amounts of mercury in the form of a vapor (gas), depending on the number and age of existing fillings, and actions such as tooth grinding and gum chewing. When a new amalgam filling is placed or an old filling is removed, patients and healthcare providers may experience a temporary increase in exposure to mercury vapor. While there are no known health risks associated with ingestion (swallowing) of small particles of dental amalgam, inhaling (breathing in) mercury vapors may be harmful in certain patients.
In general, people with multiple dental amalgam fillings may have slightly higher mercury levels in their blood or urine, however, they usually remain at a level considered safe. Studies on people with dental amalgam do not show conclusive evidence that dental amalgam causes harmful health effects in the general population.
Drawbacks of Dental Amalgam on Health:
Mercury in amalgam is a highly toxic material. It releases low levels of mercury in the form of vapours. Prolonged mercury vapour inhalation cause various respiratory problems. Also, It is harmful for the nervous system, digestive system, immune system .
Moreover, the old amalgam fillings when dislodged from the tooth, metal particles enters the body through inhalation or ingestion.
Over a period of time amalgams fillings show wear causing secondary microleakage. When a decay surrounding the filling / the filling becomes slightly dislodged from the walls of the tooth. Bacteria enters in and reaches the root leading to infection of teeth, which requires a root canal treatment. Teeth sensitivity also occurs which clearly indicates that the amalgam filling needs to be replaced.
In addition, amalgam fillings made of metal expand and contract due to hot or cold food respectively. This may lead to fracture of teeth or cracking of teeth and loosening of the filling creating gaps for the bacteria to get in. Amalgam filling also requires preparation of cavity that involves more loss of tooth structure in contrast to the tooth coloured restoration (composite) that are with very conservative cavity preparation.
Also amalgam fillings are not esthetically pleasing. If the amalgam fillings are in good condition and worn out or broken there’s no need to replace such fillings because removal of such fillings may lead to unnecessary mercury exposure.
How do SAPTeeth manage the forces of teeth bite?
Natural Teeth: Crowing or capping of natural teeth is indicated in cases where the tooth is damaged due to infection, mobility, and cavity or has been altered by cosmetic dentistry, in such cases the ability of the Sharpe’s fibres reduces. SAPTeeth redistribute these forces and reduce the load and pressure on the natural tooth, Sharpe’s fibre and the bone.
Dental Implant: SAPTeeth aims to provide the shock absorbing capability to the teeth. Also, as in cases of the dental implant the forces acting on the implant may be in unfavourable angles. Hence, SAPTeeth reduces these forces and helps in immediate load of the dental implant.
