Colloidal Silver vs. Nano Silver

Let’s make things clear. Nano Silver ain’t your grandma’s colloidal silver. And here are 3 reasons why:




When comparing nano silver and colloidal silver, it is important to understand what biocompatibility is. This means that it is safe to be used and will respond appropriately in certain conditions. Biocompatibility is dependent on two things: the size of the particle and what is used as a capping agent. First off, colloidal silver particles are made without a capping agent. This means that they fall apart easily. Second, colloidal silver particles are inconsistent in size. On the other hand, silver nanoparticles are capped with plant extract. This makes them more stable and nontoxic to human tissue. 

In addition, with advancements in technology, nanoparticles found in nano silver are more consistent in size than particles found in colloidal silver. This is one of the major benefits of nano silver, as a more consistent particle size means more consistent results.




Colloidal silver does not have the ability to stay stable in various conditions when compared to nano silver. This is because colloidal silver is made through using the physical electric model by running a current through silver wires. This results in a division of silver particles and ions that are without capping agents and unstable outside of water.

Silver nanoparticles are stable because their plant-based capping agent keeps them from decomposing. And, they respond favorably to various environments such as salts and biomolecules. This makes a nano silver solution much more effective than a colloidal silver solution with unstable ions and inconsistent particle sizes.


Reaction to Biofilm


Biofilm is the layer of bacteria that builds up over the surface of your teeth, commonly referred to as plaque. How nano silver and colloidal silver solutions react to biofilm plays a crucial role in how effective they can be at penetrating the outer coating of the oral biofilm . Colloidal silver cannot be used with other beneficial agents and has a weak effect on the biofilm. Therefore, it does not do a sufficient job protecting enamel and balancing the oral biofilm by reducing acid. Because of the benefits of Nano Silver, it can be used at much lower concentrations and can latch onto and penetrate biofilms with ease. Nano silver solutions also release silver ions directly inside the biofilm and target acid, which is beyond the capabilities of more traditional colloidal silver solutions.
