Did you know, approximately 75% of Australian dentists still turn to amalgam when it comes to undertaking fillings for back teeth. This is despite the fact that over 50% of amalgam fillings is mercury. Mercury is a highly toxic substance that is linked to many dangerous conditions, including:
- Autoimmunity diseases
- Alzheimer’s disease
- Kidney dysfunction
- Food allergies
- Multiple sclerosis
- Thyroid problems
The Amalgam Filling Removal ProcessThe toxicity in amalgam fillings means the removal process has to be performed delicately. The process should work like this:
- A rubber dam should be placed around the tooth.
- An alternative air supply, in the form of a high-volume vacuum, should be used to catch all vapours released into the atmosphere. This will help ensure that both the dentist and the patient are not exposed to mercury.
- Dentists and staff should be fitted with masks and glasses.
- The amalgam filling needs to removed in large parts, to make the process move as quickly as possible.
Replacing the Amalgam FillingDespite the toxicity, the amalgam filling does perform an important function, which is why the replacement is just as necessary as the removal. The best material for fillings is composite resin. This material is optimum because:
- It is entirely invisible within the mouth
- There is no need to drill out the tooth to place the filling, meaning there is less stress placed on the teeth and surrounding tissue
- The material is entirely non-toxic and biocompatible
- The material chemically bonds with your teeth, so it doesn’t just fill a hole it actually supports the structure of the teeth
- You will be placed under local anaesthetic to ensure you don’t feel any discomfort throughout the process.
- The cavity will then be cleaned out, to ensure all decayed tissue and debris is removed.
- The composite resin is poured into the cavity and then set using a laser beam.
- The filling is trimmed and shaped until you have the perfect bite.
