Safe Mercury Removal

Safe Mercury Filling Removal

Many people do not realize that “silver” amalgam fillings are 50% mercury. A large filling may contain as much mercury as a thermometer. Mercury vaporizes easily at room temperature, and in this state, is odorless, colorless and tasteless. Inhaled mercury vapor is readily absorbed into the bloodstream. The World  Health Organization has concluded that dental fillings contribute more mercury to a person’s body than all other sources of mercury combined. Mercury is a powerful poison. We at Aesthetic Dentistry are knowledgeable in modern techniques of proper mercury filling removal.

Safely Removing Mercury

Amalgam (Silver) Fillings

I’ve spoken with thousands of people over the past 30 years and discovered that the majority of them don’t realize that amalgam fillings are harmful to their health. Most don’t even know that 50 percent of their amalgam (silver) filling is mercury. Still more people don’t know that amalgams give off toxic mercury vapor, and the fraction who do know don’t realize how much vapor these fillings release when removed without a safe protocol. For example, the World Health  Organization (WHO) estimates that those with amalgam fillings receive up to 17 mcg of mercury per day from their fillings. That pales in comparison to the 4,000 mcg of mercury released when an amalgam is unsafely removed. The good news here is that when a dentist uses a safe removal protocol it can reduce your exposure to mercury vapor during the removal process by up to 90 percent or more. So, given the vast amount of mercury that can be released during amalgam removal, it’s imperative to understand the difference between the safe removal procedures that mercury safe dentists use and what pro-amalgam dentists do (or rather, don’t do).

To date, the mercury safe dental community hasn’t reached a universal consensus on a protocol for minimizing a patient’s exposure to mercury during amalgam removal. But the International Academy of Oral Medicine and Toxicology (IAOMT), a network of dental, medical, and research professionals, has established what I believe to be the best guidelines for safety removing these fillings.  My research has shown that their guidelines are those most often incorporated by mercury safe dentist when developing their own removal protocols.

– The guidelines I recommend for safe amalgam filling removal have been taken from several sources: the IAOMT, my own experience and research, and other prominent holistic and biological dental organizations.  While using this preventative approach to minimizing mercury vapor exposure is important for everyone, it’s an absolute must for those who:

– are pregnant and nursing

– suspect or know they are allergic to mercury

– have ever had any adverse side effects during or after having amalgam fillings placed or removed

– have a compromised immune system, numerous allergies, or other serious health problems

    Some dentists don’t follow every one of the guidelines I list in the following section, while others to even further. I Believe the IOAMT protocol is more than adequate and should be acceptable to most dentists who subscribe to the basic concepts of mercury safe dentistry.

Still, new information emerges each year about the safest way to remove amalgam fillings, and it’s possible that a new technique or approach may be added after the publication of this book. Thus, if your dentist says he or she is mercury safe but deviates from the protocol I’ve included, it doesn’t mean his or her protocol won’t be effective. But if it varies too much, make sure you get a satisfactory explanation as to why.

Mercury Amalgam Fillings: Safe Removal Protocol

There are 11 procedures that most mercury sate dentists use to minimize mercury exposure to the patient, the dental staff, and the environmental during amalgam filling removal. They are divided into four categories:
– minimizing the amount of mercury that could be released from the filling
– intercepting the mercury that escapes the filling before the patient breathes it in
– filtering the office air
– cleaning the patient and disposing of contaminated material, such as patient coverings, gloves, and rubber dam

I . Cooling the Fillings
The amount of mercury vapor released from an amalgam filling is directly proportionate to its temperature. Drilling out an amalgam filling generates a tremendous amount of heat. Cooling the filling by using as much water as possible during the process will significantly reduce the amount of mercury vapor released.

2. Chunking Amalgams
Mercury safe dentists use a removal process called “chunking” in which they use
a special drill bit to section the filling into large chunks. These chunks can then
be easily removed by a hand instrument or suction, which reduces drilling time
and therefore the amount of mercury vapor released.

3. Using High-Volume Evacuation
Mercury safe dentists use a powerful suctionlvacuum system. This important
piece of equipment minimizes your exposure to mercury vapor because in effect
it intercepts the vapor before you can breathe it in. The tip of the suction/vacuum
hose will be placed as close to the filling as possible during the entire removal
process. This procedure captures most of the mercuryvapor and particles released
as the filling is removed.

4. Providing an Alternative Source ofAir
All mercury safe dentists adhere to the first three protocols, but not always this
fourth one-giving you an alternative source of air to breathe. Some feel that
as long as the first three procedures are strictly followed, this isn’t necessary.
But if any one of the first three procedures isn’t followed, you should request an
alternative source of air during the entire removal process. If your mercury safe
dentist doesn’t provide one, be sure to ask him or her if they’re using a highvolume
evacuation system and if the other protective methods listed above are
being used. However, if you are in the high risk category, especially if you are
pregnant or nursing, I would insist on an alternative source of air.
An alternative source of air is provided by a nasal hood, which covers your
nose. Through this hood you breathe either compressed air or oxygen from a
tank. I don’t believe an alternative source of air is necessary after the fillings
have been removed.  You should always concentrate on breathing through your nostrils and avoid breathing through your mouth while your mercury fillings are being removed whether you are provided with an alternative source of air or not.

5. Using a Rubber Dam
The rubber dam was designed to isolate the tooth or teeth being worked on,
making it easier for the dentist to see and protect the toothlteeth from bacteria,
moisture, and the tongue. The rubber dam is made from either latex rubber or
silicone for those allergic to latex. It is very thin and flexible, comes in various
colors, and can range in size from 5 x 5 inch to 6 x 6 inch squares. Until recently,
dentists believed that the rubber dam would protect the patient from inhaling
mercuryvapor through the mouth. It’s now known that mercuryvapor can readily
pass through a rubber dam made from latex, the most common rubber dam
material. (Silicone is more resistant to mercury vapor.)
A large percentage of patients believe that the rubber dam offers the greatest
protection from mercuryvapor and insist that it be used. But because the rubber
dam doesn’t actually protect you from inhaling mercuryvapor, it isn’t absolutely
necessary for the safe removal of amalgam fillings. Although the rubber dam
offers little protection against mercury vapor, it does make it easier to evacuate the
filling material and prevent amalgam particles from being swallowed. Amalgam
particles can’t be absorbed into the body, but it’s always wise to avoid swallowing
any dental material. More and more dentists are now using a dental device called the Isolite System that illuminates and isolates the tooth and provides a constant source of suction close to the amalgam. It’s often used in place of the rubber dam, and I believe it’s more effective at protecting the patient from mercuryvapor and amalgam particles. As a rule of thumb, when it comes to choosing between the rubber dam and any alternative, I recommend trusting your mercury safe dentist to decide when and which one is or isn’t necessary-but if in doubt, ask for an explanation.

6. Cleaning Up Immediately
Once the removal process is completed, the dentist and assistant should remove
and dispose of their gloves and the rubber dam (if used) and thoroughly rinse
and vacuum your entire mouth for at least 10 seconds. This process helps remove
amalgam particles and residual mercury captured by the saliva. You should
make every effort not to swallow during the short rinsing procedure. When this
is finished, take a small amount of water and gargle as far back into your throat
as possible. Once you’ve gargled, don’t swallow this watery residue! It should be
evacuated by the dental assistant, or spit into a cup. In addition, when the removal procedure is finished, the dentist or dental assistant should remove and dispose of your protective covering and clean your face and neck. All mercury safe dentists should routinely do this, but remind the assistant if she or he forgets. After all, you don’t want to take any mercury
home with you.

7. Using Additional Air Purification
Some mercury safe dentists use an additional air filtering system that’s placed
as close to the patient’s mouth as is practical. The more popular ones resemble
an elephant’s trunk and have an opening about 4 inches in diameter. This filter
is helpful, but there are other mercury safe dentists who believe that the patient
can be adequately protected without such a system. More and more mercury safe
dentists are using this type of office purification system, and while it’s a positive
addition to the basic removal protocol, I believe this system is more effective at
protecting the dentist and assistant than the patient.

8. Filtering Air in the Dental Operatory
Many mercury safe dental offices filter the office air because they work in it all
day and it’s to their benefit to do so. Thus, doing this is more important for the
dentist and staff than it is for you. Although mercury safe offices don’t put in
amalgam fillings, they certainly remove them. You should be encouraged by the
fact that mercury safe dentists also want to take the necessary precautions to
protect themselves and their entire staff from excessive exposure to mercury.

9. Using Activated Charcoal
Although definitive studies haven’t been done, there is some evidence that shows
that activated charcoal taken 10-15 minutes before amalgam removal can capture
swallowed elemental mercury and mercury vapor, allowing it to be harmlessly
passed out of the intestine via the feces. I consider this to be optional, as only 0.01
percent of swallowed elemental mercury is absorbed through the intestine. But it
can’t hurt to add it, especially if you are in the high mercury risk category.

l0. Vitamin C Infusions
Some dentists and health professionals consider vitamin C (ascorbic acid) infusions
to be an effective method of protecting the body from mercury vapor during the process of removing amalgam fillings. Based on my evaluation of the available data, who support the  vitamin C protocol believe that it can protect the body from mercury vapor when it is in the bloodstream. While I don’t consider this an essential procedure for the majority of patients, if you’re allergic to mercury, have numerous symptoms and diseases related to chronic mercury promised immune system, I would recommend these if available. Since its administered intravenously, a vitamin C infusion needs to be coordinated with your dentist and a qualified health practitioner. To date, few dental offices offer this service. But if you feel vitamin C protection would be beneficial and can’t find a dentist who will arrange an infusion, you can take an oral dose. However, this method is less effective because the blood levels of vitamin C obtained with an infusion would be significantly higher than from an oral dose. Still, oral vitamin C could provide some additional protection from mercury vapor while it’s in the bloodstream. Before doing this, discuss it with your dentist. If you are in agreement, obtain a packet of powdered vitamin C from a health food store and take it with you to the dental office. After the area to be treated has been effectively numbed, dissolve the powdered vitamin C in a glass of water and drink it as soon as possible before the removal procedure begins. Because vitamin C may diminish the effect of the anesthetic in some people, I recommend taking it after the anesthetic has been given and the part of you mouth being worked on is numbed. This method works better on an empty stomach because vitamin C is quickly absorbed from the intestine into the blood stream if no other food is present in the stomach.

11. Supplements
I recommend that everyone start a mercury detoxification program before the fillings are removed.
