Are amalgam fillings really harmful? Do they need to be removed? If so, how can they be removed safely? In this article we answer all your questions.
What is Amalgam Filling and Why is it Controversial?
Amalgam dolgular, cıva, gümüş, kalay ve bakır karışımından oluşan, diş tedavisinde uzun yıllardır kullanılan bir dolgu türüdür. Dayanıklı ve uzun ömürlü olmaları nedeniyle yıllarca tercih edilmiştir. Ancak içerdiği yaklaşık %50 oranında cıva, zamanla sağlık açısından endişelere yol açmıştır.
In recent years, many studies have shown that amalgam fillings can have negative effects on the nervous system and immune system due to the release of mercury vapor. But is it really dangerous?
The Harm of Amalgam Fillings - What Does the Latest Research Say?
1. Mercury Vapor Release
Amalgam fillings wear out over time and mercury vapor can be released, especially when chinning (grinding teeth), consuming hot and cold foods or chewing. This vapor can enter the body through the lungs and have negative effects on the nervous system, kidneys and immune system.
2. Effects on the Nervous System
Some studies on mercury exposure show that amalgam fillings can cause neurological problems such as: -concentration disorders, -memory problems, -headaches and migraines, -depression and anxiety.
3. May be Risky for Pregnant Women and Children
The World Health Organization (WHO) and the European Union do not recommend the use of amalgam fillings for pregnant women, nursing mothers and children. Some countries such as Norway, Sweden and Denmark have completely banned the use of amalgam fillings.
Therefore, it may be important to have your amalgam filling removed, especially if you are in a risk group. However, the most important point to be considered here is that the removal process is carried out safely.
Things to Consider When Removing Amalgam Filling
If the wrong method is used when removing amalgam fillings, you can be exposed to high levels of mercury vapor. Therefore, the removal process should be carried out professionally and certain safety precautions should be taken.
Wrong method:
Cutting and removing the amalgam filling directly with a milling cutter causes a high emission of mercury vapor.
The right method:
The Safe Amalgam Removal Protocol (SMART Protocol) should be applied.
Safe Amalgam Filling Removal Method - SMART Protocol
SMART (Safe Mercury Amalgam Removal Technique) is a method that aims to protect the patient from mercury vapor and particles.
1. Use of Rubber Dam
A rubber dam is placed over the patient's mouth to prevent the ingestion of mercury particles and vapors. This is the most critical step!
Why is a rubber dam important?
Prevents ingestion of amalgam fragments.
Protects the inside of the mouth and gums.
The patient does not come into contact with the toxic substances released.
2. Powerful Vacuum Systems
Special high vacuum aspiration systems should be used when removing amalgam fillings. These systems immediately extract the mercury vapor and particles and prevent them from spreading into the air.
3. Using a Cooled End Mill
Without overheating the drill, the amalgam filling should be removed in small pieces by cooling with plenty of water. In this way, mercury vapor is minimized.
4. Use of Oxygen Mask
An oxygen mask or special nasal apparatus should be used to allow the patient to breathe fresh air through the nose. This prevents the patient from inhaling mercury vapor.
5. Protective Measures for Physicians and Staff
Masks with special air filters
Protective goggles and gloves
Use of special clothing for patient and dentist
These measures minimize mercury exposure for both the patient and the healthcare staff.
Which Alternatives Should Be Used Instead of Amalgam Filling?
There are safer and aesthetic alternatives to amalgam fillings:
Composite fillings: BPA-free, white aesthetic fillings.
Ceramic fillings (Inlay/Onlay): Durable and biocompatible materials.
Zirconium veneers: Aesthetic and long-lasting options.
Conclusion Should Amalgam Fillings Be Removed?
If your amalgam filling is damaged, broken or you have chronic health problems, removal is recommended.
But if not removed safely, mercury exposure can lead to serious health problems.
Dismantling without rubber roof and other safety precautions is risky!
Dental health can be protected by choosing a healthy alternative.
If you are thinking of having your amalgam filling removed, you should consult a dentist who follows the SMART protocol.
