Identify one possible dilemma
-The nano particles could affect our friendly bacteria

Point out the advantages and disadvantages of using the Nano Silver toothbrush
Advantages: More germs are killed than with a regular toothbrush Disadvantages: The effect of nano particles possibly entering the body and bloodstream is unknown

What is your opinion?
We think that this tooth brush is very effective and wil help with oral hygiene, because the toothbrush has the ability to kill 99.7 percent of the bacteria in your mouth. However, we think that more research should be done before the toothbrush is released to the general public, because although it seems more effective than a regular toothbrush, its full effects on the body are unknown.

Please justify your opinion
Nano particles could be potentially damaging to our bodies and health, so the toothbrushes should not be distributed yet, because they could have harmful and negative effects on our bodies.
