The cell is one of the basic building blocks of the human body and cell biology is a fascinating subject. A lot is known about how cells function but a lot remains a mystery as well. For instance the DNA and RNA combine to make up only about 1.5% of the cells they inhabit, yet contain an unbelievable amount of information.
The information packed into the DNA of your genes, when translated into English letters, would fill two hundred New York City phone books.
On the outside, our cells are covered with a membrane which allows materials to pass in and out. Essentially, it allows food in and lets toxicity out. How well this transport occurs depends to a large degree on the osmotic pressure of the cell membrane, which in turn depends on the quantity and quality of the alkaline elements sodium, potassium, calcium, and magnesium.
Because our cells are the most basic functional unit within our bodies, our cells must be healthy for us to be healthy. Cellular health is determined by the right balance of the four alkaline elements and the availability of the highest amount of absorb-able nutrients. With the right nutrients a cell may be able to live forever! Some other interesting facts about atoms and cells:
• Cells with different functions have different shapes
• In each human cell there are 24 pairs of chromosomes
and 25,000 genes.
• The atom is the most basic element of all life. Imagine that the nucleus of an atom is the size of a tennis ball. Then the electrons that circle around it would extend out as far as a square city block.
• Likewise if the atom were the size of a pea, a cell would be the size of a cruise ship, and the human body would be the size of North America.
• The average adult human body is made up of 40-50 trillion cells, enough to stretch around the planet 40 times over. Pretty amazing.

Carey O’Rielly DDS has been a practicing dentist for 35 years. He went to USC Dental School and Duke University for his undergraduate degree. He grew up in Laguna Beach and now lives in La Costa with his wife Victoria, who runs his office.
He began his career by owning and operating a network of six offices in the San Francisco Bay Area. Presently he owns a private holistic practice in North County San Diego’s Encinitas.
Dr. O started looking for solutions to his health challenges that resulted from the stress and environmental toxicity that built up over a ten year period running his dental network. He has dedicated himself to learning about oral systemic problems and how dentistry can affect your health. He has applied what he has learned over the last twenty years to ensure he, his staff and his patients are protected from the chemicals and toxic materials found in most dental offices. He has produced an environmentally friendly office that is also peaceful and calm.
He is an expert on dental materials having looked at hundreds of biocompatibility lab tests over the years. He has identified the most bio-friendly materials to use in his practice and which dental materials can be used to replace metal fillings and crowns, including BPA free and fluoride free ‘white’ fillings. He also uses metal-free Zirconia or ceramic implants and PRF (platelet-rich fibrin) grafting materials which come from the patient’s own blood.
Dr. O’Rielly teaches C.E. courses on the systemic effects of gum disease. He is an expert in using phase contrast microscopy for analyzing dental infections, where he shows patients what kind of microbes, i.e. bacteria, amoeba, and yeasts like candida are populating the mouth and affecting the body as a whole.
He has an educational blog and is writing a book on dental health called ‘Hidden Dental Infections: Healing Root Canals and Infected Teeth with the Erbium Laser’ where he discusses dental nutrition, toxic dental materials and the effects of old root canals on inflammation and overall health.
