Protecting You and Our Environment

Protecting You and Our Environment

Fifteen years ago I became one of the first dental practices to install digital x-ray system in our office. I am still excited because every x-ray we take has 80-90 per cent less radiation than traditional dental x-rays. Using the digital system also eliminates the dental developing and fixing chemicals. By eliminating them none of us are exposed to these toxic chemicals and do not have to breath them in. It also eliminates disposing of them into our environment. We also have filters that remove mercury and other chemicals from the air while we work. We have specific air filters to remove mercury and a filter on the waste line that also traps the old amalgam that is removed from the tooth. We place any mercury amalgam scrap into a sealed container for disposal by a hazardous waste company. Our lead apron recently wore out and we wanted to replace it. We also wanted to dispose of it safely as lead is another big concern in the environment. My assistants, Xia and Katlyn spent hours searching for a safe place to take it for disposal.

We have also reduced the use of chemicals in our office by using melaluca which is natural and also an approved disinfectant. We even filter our office water supply with reverse osmosis and carbon block filters to provide pure water for drinking and for use in the dental water we use for procedures and for the laser.  

I came across the following information about mercury and the environment from Dr Mercola. Dr Mercola is a ostheopathic physician and a health advocate and he has many interesting articles on his web site. He sends out a free daily health newsletter. This is from his newsletter:

Coal Plants and Dentists May be Accelerating Wildlife Extinctions 

Coal generates 54 percent of the electricity in the United States and is the single largest cause of air pollution. Coal fired power plants are also the number one source of environmental mercury pollution. Mercury is extremely tenacious once in the air, water and soil, and levels gradually increase over time, as it accumulates.

Each coal plant discharges an average of 170 pounds of mercury into the air each year, along with other pollutants. There are about 600 coal plants in the United Statesⁱ. So, if you do the math, you will discover that coal plants in the U.S. are releasing about 51 TONS of mercury into the environment each year. Just one gram of mercury can make the fish in a 20-acre lake unfit for consumption for a year.

A study by Island Restoration Network found dangerous mercury levels in 68 percent of swordfish, high enough to cause harm to wildlife. Recent evidence indicates mercury is now present in all fish. Other studies have demonstrated high levels of mercury in sensitive and endangered species across marine, freshwater, and terrestrial ecosystems, indicating that mercury pollution may be a significant factor in species population reduction.

The second largest mercury polluters in this country are dental practices. As a result of their continued use of mercury amalgam fillings, another 29.7 tons of mercury is discharged into the air, water and soil each year from installation and removal of amalgams.

Don't let the "cheap" price of these fillings fool you. When environmental cleanup costs are included, dental amalgams are actually the most expensive type of dental fillings on the market. Besides its toxic effects to wildlife, mercury is terribly harmful to humans as well.

Another source of mercury in the environment is cremation. When a body is cremated, any amalgam fillings in the person's mouth are vaporized into the air and then is put forth into our environment.

We try to be very conscience of our environment and how we can best serve our patients. We make efforts in any way that we can to eliminate harmful chemicals from our office, as well as safe handling and disposal of metal's that are harmful to our environment.

Stay well!

Dental Air Vac

Hello everyone!

Many people who come into our office for treatment ask, "What is THAT thing? It looks like an elephant!" Well, we thought we'd take this blog post to explain what THAT thing is!

This is our Dental Air Vac. You may be wondering what it is used for. Well, we use our Air Vac for many things, but primarily it's use is for safe amalgam removal. This vacuum has 3 filters in it to safely remove amalgam vapors from the air. First, it has a pleated pre-filter that is able to capture particulate down to about 7 microns. The second, and most important filter is the HEPA filter that is able to capture and contain particulate down to 0.3 micron. Finally, the last filter is a blended carbon filter and is specifically designed to capture and adsorb particulate finer than 0.3 micron as well as sub-micron odors and vapors. These filters are safely replaced every 3-6 months or 6-12 months, depending on the manufacturer's recommendations.

So what we do is we turn this filter on and bring the end of the "trunk" down close to the patient's nose and mouth. When we remove old amalgams, we use what is called a "rubber dam" and that prevents amalgam particles from being swallowed, while at the same time the Dental Air Vac is removing the harmful mercury vapors from the air. This is important because the mercury vapor coming off the tooth as it is being drilled is virtually undetectable to the naked eye, but it is the most harmful form of mercury, so having the vacuum filter close to the patient's face is extremely important, not only to you, but to us as well! We use masks, glasses and gloves, but we like to take the extra measure of protection to help our patients and staff.

This filter is also used in our office when we have patients who are chemically sensitive. We like to make sure all of our patients are well taken care of and are having their particular needs met. When someone comes to us with a chemical sensitivity, we can use this vacuum to clean the air before, during and after their appointment. Although we do not use harmful chemicals in our office, some of the the dental products we use have a scent to them, so this helps to pull away that scent before it reaches the patient's nose.

So next time you come in for treatment or for an exam, be sure to check out our Dental Air Vac! We are always happy to explain it's use to anyone who asks.

I hope you are all doing well!

Why Dental Examinations and X-rays Are So Important

Why are dental examinations and x-rays so important?

Dental conditions can change rapidly. Unfortunately, tooth decay and gum disease and even abscessed teeth often don't hurt. This is especially true with gum disease but tooth decay as well. The reason I say unfortunately is that if it hurt you would do something about it. Often times clients mistake no pain in the teeth and no bleeding gums when they brush as everything is fine. Virtually every day that I see clients we find something significant that the client was unaware of. The earlier we find a problem the easier it is to correct. My focus is on prevention of disease, and minimally invasive bio-compatable dentistry. Often times a client can prevent problems by making a few changes, such as: changing the way they clean their teeth, a diet change or taking anti inflammatory foods and herbs. The key to doing that is early detection. Find it before the problem is not reversible. Once problem is not reversible, we want to find it before it is a big problem. In the early stages the problem is easier to correct and less expensive. Even if it is more advanced when we find it we can often prevent bigger problems such as root canals and/or surgery. Again, the key is early detection. Early detection depends on having a dental team that focuses on excellence in diagnosis. Yesterday a patient told our receptionist, Kendra, that it is too expensive to come in twice a year for an examination and preventive care. I completely understand that. The challenge is that I saw several clients last week that had not come in for one to three years. Some of these people needed significant dental treatment. Most of it was preventable. So much can change in a relatively short time in the mouth. The best dental insurance isn't Washington Dental Insurance. It is brushing your teeth and gums at least 2 times a day. Floss your teeth at least one time a day. Avoid refined sugars. Come to the dental office two times or more per year for examination and preventive care. It is not a guarantee you won't have problems but it absolutely minimizes them. If there are problems we can prioritize them to reduce the impact of said problems.

Yesterday I had a client who refused x-rays. I understand why. I am sensitive about x-ray myself. I do not let TSA x-ray me at the airport because a hand search is simple. I have taken precautions to make our dental x-rays as safe as possible. I got one of the first digital x rays systems in Seattle in 1996 because it reduced x-ray exposure 80-90%. By getting this system I was able to eliminate the toxic developing and fixing solutions from our office so we don't have to breathe them or dispose them into the environment. The state of Washington inspector visited us last fall and found our system to be working perfectly. He commented that our system put out about 40% less than even other digital systems.

We use a lead apron to cover potentially sensitive areas. We even have a green tea extract that has been reported to have protective effect when exposed to x-ray.

Here is an actual patient x-ray showing what can be found underneath. None of these things hurt but the abscess is dumping toxins into the body. The decay is almost to the nerve. It looks like three root canals would be necessary with build ups and crowns. The back tooth might need to be removed. So there is a real benefit to having x-rays at the recommended interval which I customize to each patient depending on their risk factors. If you ever have questions about the reason why we make a recommendation do not hesitate to ask.

Be well,

Richard Stickney
