Identify one possible dilemma
There is lack of information about nanoparticles being embedded on our toothbrushes. Nanoparticles might enter our bloodstream easily and might affect the blood system, and might harm friendly bacteria.

Point out the advantages and disadvantages of using the Nano Silver toothbrush
When we brush our teeth, we leave millions of germs and fungus on the toothbrush. By incorporating nano technology into nano silver toothbrush it kills 99.7% of the germs in 6 hours. The disadvantage is that the nanoparticles could easily enter our bloodstream which might affect the blood system and harm friendly bacteria.

What is your opinion?
We believe that nanotechnology can effectively help diminish germs, bacteria, and fungus often trapped in our toothbrush. To a certain extent, it can improve hygiene condition over time. However, since not enough research has been conducted, it is not an extremely safe method of incorporating nanotechnology to improve health conditions in our lives.

Please justify your opinion
Nano antibacterial toothbrushes are not proven to be completely safe, and more research should be conducted first to ensure that nanoparticles do not eg. enter our bloodstreams and affect friendly bacterias
