Identify one possible dilemma
The bacteria remains on the toothbrush and spreads.

Point out the advantages and disadvantages of using the Nano Silver toothbrush
Advantage: Kills bacteria Disadvantage: Only kills 99.7% of germs, nano particles could be harmful to the friendly bacteria within humans due to their minuscule size.

What is your opinion?
I think that using a nano toothbrush could be helpful in the short term but harmful in the long run.

Please justify your opinion
Although in the short term, the toothbrush can eliminate a majority of germs, scientists have stated that it can be harmful to the friendly germs in our system. However, this is still a innovative product that promotes oral hygiene, the negative effects may override the positive effects.
