Our Aim & Mission

Our approach at Oldmachar Dental Care is not to pressure patients to rush to remove their mercury fillings at once. However, we decided to be a Mercury Free dental practice. We believe that it is in the best interests of our patients’ to use only materials that are healthy for the body. This means materials that are well accepted by the body and won’t cause any heavy side effects in the future.

We use ceramics and white fillings for our restorations. Our practice is dedicated to a holistic approach to dentistry. By getting to know you and your needs, we can create an individual treatment plan for your dental health and aesthetics.

What is amalgam?

Dental amalgam is a common material used to fill cavities and has been widely used in dentistry for 150 years. Fillings made with amalgam also are known as silver fillings. Over the years, concerns have been raised about the use of amalgam as it contains mercury. Amalgam fillings are alloys containing silver, mercury and trace amounts of tin, copper and zinc.

What is Mercury?

Mercury is a naturally occurring chemical element. It comes in liquid form, like in thermometers and also when heated, as a gas. Amalgam can also be mixed with other materials.

Effects of Mercury

Mercury has a strong affinity to lipid or fatty tissue. The biggest organ accumulation of fatty tissue is the brain and nervous system. This can have an effect on the endocrine and immune systems.
People have varied immune system responses. A breakdown of the body’s immune system often presents a varied number of symptoms.
The presence of other heavy metals, notably lead, cadmium, aluminium and nickel, worsen immune depression.

In a 1997 publication the British Dental Association stated, “About 3% of the population are estimated to suffer from mercury sensitivity.” From a population of 65 million that is 1.75 million people in this country with showing symptoms from mercury toxicity. A large number indeed!


Our Amalgam Removal Procedure and Safety Protcols

Removal Procedure
  1. Local anaesthetic is placed or alternative pain relief where requested.
  2. The rubber dam is placed, supported with a special clasp around the tooth. The patient is able to breathe through the nose and swallow beneath the rubber dam. To communicate, patient should raise their left hand and we will provide pen and piece of paper to write any questions or special requests throughout.
  3. Amalgam filling is carefully removed with a special bur that reduces mercury vapour and the nurse aspirates (provides suction) throughout. The tooth is cleaned and then a new white composite filling is placed.
  4. Rubber dam is removed.
  5. Before and after photo is presented to the patient.
Safety Protocols
  1. During procedure only the teeth being worked on are exposed. In order to achieve this we use a rubber dam (a latex free rubber sheet) that is placed over the mouth. If the patient does not feel comfortable with this, we have an alternative method using a special frame that stays in the mouth during the whole procedure, and just protects the lips from exposure.
  2. We use an external suction device within the room that filters the air and collects all mercury vapour in order to protect patient and operators against inhalation.
  3. We also use very powerful chair side suction which is operated by our trained nurse. This makes sure that all amalgam particles are removed and the oral cavity is protected.
  4. We can also provide you with a separate oxygen supply. (An extra charge applies for this)
