Old amalgam fillings can cause the following:
- Leakage in the tooth
- Corrosion of fillings
- Cracks in the tooth
- Fracture of the tooth
- Major tooth loss
- Infection in the nerve
There has been a lot of negative literature about amalgam fillings in recent years because mercury makes up 40–50% of the amalgam filling compound. Some of the concerns are valid, particularly for people who have conditions such as mercury sensitivity, kidney dysfunction, or skin-related autoimmune disorders, or for children who need to have teeth filled.
However, numerous studies have been conducted in various countries regarding the safety of amalgam fillings. None of these studies have found any link between the mercury in amalgam fillings and brain or nervous system functioning, adding to the growing body of evidence that amalgam is still a safe and effective way to treat teeth that have been affected by tooth decay or trauma.
Apart from toxicity, there are a few other concerns that prompt people to think about replacing amalgam fillings. Mainly they look ugly in a white tooth, and over a period of the time they tend to create cracks in the tooth. These cracks are similar to a crack in car windscreen – you never know when it is going to explode. In the same way, a crack in the tooth can lead to major structural tooth loss, which is sometimes difficult to restore as well as expensive. These cracks can also travel deep into the tooth towards the nerve and so provide a pathway for bacteria to enter the nerve. This is another common cause of sensitivity or toothache, which may warrant root canal treatment and a crown.
