A Simple Way to Say Good Bye to Gum Disease Using Salt

Updated on March 9, 2012

Good news to people with weak gum that swells and bleeds easily. A simple way to escape from gum disease has been introduced on Twitter. You don’t need to go through painful treatment at the dentist’s, and you hardly need any money at all. All you need: a cup and enough salt to make concentrated salt water.

The main cause of gum disease is the germs that live on your toothbrush. So here is what you need to do. Make concentrated salt water in a cup, and leave your toothbrush immersed in the salt water. Then the germs on your toothbrush will burst to death due to osmotic pressure. Simple, right? If you use this simple method, you will be able to stop all gum diseases that results from germs on your toothbrush.

How Does this Work? What is Osmotic Pressure?

Osmotic pressure is the water pressure a cell’s membranes experience when water passes through them. Membrane is like a cell’s skin (in fact, your skin is a membrane, too!), and water can pass through cells’ membranes.

Then when and why does a membrane let water pass through it? And which direction does the water flow? In to the cell, or out of the cell? This all depends on the concentration of the fluid inside and outside of the cell.

Let’s think about a water fall. Which direction does the water flow? From high to low, right? The direction of water through a cell’s membrane is very similar: high to low. But in membrane’s case, we’re not talking about height, but amount. Water flows from where there’s more water to where there’s less water (from watery to saltier). So if a cell is in salt water, water will flow out of the cell, and when a cell is in plain water, water will flow into the cell.

*If you want to learn more about osmotic pressure, visit the wikipedia link at the bottom of this hub. There, you will find details about osmotic pressure, along with all the science stuff.

Osmotic Pressure in Real Life: Wrinkly Fingertips in Bathtubs

Science is boring when it is in books. So let’s look at simple real life example of osmotic pressure. When you are taking a bath for a long time, you will see that your fingertips getting wrinkly. It is because since the water surrounding your skin is less “saltier,” your skin absorbs the water, hence becoming inflated with water (swelling).
