Are Fillings Containing Mercury Safe?
Amalgam is a common material to fill cavities. The silver material contains mercury. The safety of mercury in the mouth has been questioned by many health care professionals. You probably know what these are if you’ve had them or seen them in someone’s mouth. It’s the silver that shows in the middle of back teeth. They fill in the cavity. Is it safe to have silver fillings in the mouth? Biological dentists all believe the amalgam fillings are not safe. But with many people trying to improve their health, metal fillings have truly become a main stream concern. Especially for people having health problems such as cancer, auto immune disease and dementia.
Possible problems with Metal Fillings
- Memory Loss
- possible metal allergies and sensitivities
- galvanic reactions with other metals in the mouth including other silver fillings, gold crowns, titanium implants, etc
The problem with silver amalgam that causes concern is that amalgam is a metal that contains mercury. Since mercury is unsafe to the body, do silver fillings pose a threat since they contain mercury? Many dentists, doctors and the FDA believe silver fillings are safe despite containing poisonous metals including mercury. Some dentists and doctors believe amalgam fillings are not safe. An organization called the IAOMT is a group of dentists and doctors who believe silver fillings are not safe. The IAOMT has a safe mercury amalgam removal protocol for people who want amalgam removed in a “safe” manner.
What is in Amalgam Fillings?
Before we answer this question, let’s understand what makes up amalgam. Amalgam is made up of several metals, such as silver, mercury, tin and copper. It also has some zinc, indium, and palladium in it. This type of filling has been used by dentists for over 150 years.
Advantages and Disadvantages of Tooth Colored Fillings
Recently, people have been requesting a different type of filling – a tooth-colored one. Most if the time, this is not because of health or safety concerns, but because they don’t want to see the metal in their mouth. Unfortunately, tooth colored fillings are more expensive than mercury fillings. Also, until recently, the white fillings did not hold up as well over time. Now tooth colored fillings have many advantages over amalgam fillings are a better choice – the mercury safety issue aside.
Now that you know what amalgam is made of, you probably want to know if it’s safe. The answer is that there is risk to having it in your mouth. According to the ADA and U.S. Food and Drug Administration has stated that there is no reason to limit its use because it is safe enough for adults and children ages 6+. But there are many health professionals who feel the risk has been understated and down-played by the ADA and FDA,
Amalgam Safety Concerns
Despite the FDA’s amalgam statement, many people are still unsure of its safety. The issue is that the filling is made with mercury and with so many other sources of mercury in the environment it may tip the scales enough to make it a true health risk.
The more mercury someone digests, the worse the symptoms are for them. There is significant amounts of mercury in fish meals. Fish such as salmon, sword fish, tuna and many others can contain mercury.
What is important to know is that while researchers in the past believed silver fillings were inert and did not absorb into the body, recent studies have found that mercury vapor from them does get released and is absorbed by the body as the fillings wear. People who clench their teeth especially absorb a lot mercury vapor.
Mercury Impacts People Differently
Not all people with silver fillings get sick, but some people are allergic to it. This causes great concern for many people with metal allergies. While a lot of people do not have metal allergies, it is something that does happen and people need to know about it. A common problem with allergies is the delayed response. Someone may not be allergic to dental metal and then a year later they are allergic. The symptoms to allergies to metal in the mouth may not be rash and hives. It may be just minor gum inflammation and bleeding of the gums that persists even thought brushing and flossing is perfect.
What many people want to know when they have metal-based fillings is how they can get them removed. It is possible to have silver fillings removed and replaced with a different type of material – a safe, just as effective material. Alternatives to amalgam fillings include composites, porcelain and zirconia.
Removing Fillings with Mercury in a Safe Manner
For those who are concerned about the mercury in silver amalgam, it is possible to have it removed in a safe manner. Mercury removal is done by experienced dentists who understand the risks. The process is technique sensitive but simple for a properly trained dentist. People should do research before deciding to have it performed.
How is Safe Mercury Removal Done:
- Cutting the Filling – The first step is to remove the fillings. This is done by cutting chunks of the filling out of the tooth. This minimizes the effects of the mercury.
- Cool Instruments – The reason people should see a dentist who is experienced with mercury filling removal is because it’s important to use water irrigation and air cooling. Heat can increase the generation and emission of mercury, which could lead to harmful effects.
- Efficient Suctioning – It’s highly important to remove all pieces of the filling are removed, so it doesn’t turn into a vapor and absorbed into the body.
- Protection Barriers – Rubber dams should be used to prevent ingestion and inhalation of mercury during the removal process.
- Protecting the Skin – The dentist should also protect the body’s biggest organ – the skin. This is done by using a surgical drape or moist paint towel on the skin to catch any fine particles from the fillings.
- Clean Air – This should be available during the entire process. This prevents people from inhaling amalgam platter or mercury gas.
Video about Mercury Filling Removal
An organization called the IAOMT has defined a protocol for safely removing mercury from the oral cavity. This involves using nitrile gloves. These special rubber gloves prevent diffusion of amalgam and mercury. The protocol also includes making clean air available to the entire dental team, especially dental offices that perform amalgam removals regularly.
It is highly important to take adequate precautions when it comes to mercury removal since the debris can remain the air for quite some time. This means people can breathe the mercury in and that elevates their levels, which could be harmful. Managing the amount of mercury in the air is highly important, and something we take serious in our dental office.
Alternative to Metal Fillings
An alternative to metal fillings is tooth-colored ceramic ones, or zirconia fillings. They are metal-free, just as durable, and completely safe to use for fillings. The switch to zirconia fillings has been happening for a few years, especially since they are nearly unnoticeable when people open their mouth.
Not all dentists offer zirconia fillings, so it’s important to ask if the dental office you’re considering has them.
Using Insurance for Metal Filling Removal and Zirconia Fillings
Some dental insurance companies cover replacement of silver fillings, but only if the silver filling is defective, with a crack or a cavity under it. Many dental insurance policies do not cover metal filling removal due to the FDA stating they are not a threat to people’s health. The expense of removing the fillings may be worth it to you especially if you’re concerned about the effects of them on your health. Porcelain fillings are also not usually covered by dental insurance because of the option of less expensive metal ones. Some insurances will cover a portion of porcelain fillings up to the cost they would pay for the metal ones, and the rest of the cost is the responsibility of the patient.
Ask your insurance provider or dental team to check on what is and isn’t covered, so you can plan on the expense.
