5. Conclusion

5. Conclusions
After this experiment, we can conclude that mouthwash can kill most of the bacteria but NOT ALL in our mouths.


5.1 Practical Applications
Those well known mouthwash brands like Colgate, have a statement on their mouthwashes, that says “kills 99.9% of bacteria”. Through this experiment, the mouthwash we used really killed most of the bacteria in our mouth. As everyone’s mouth have different amounts of bacteria before and after eating, this may vary the results of the experiment.


5.2 Areas for further study
We can possibly research on whether we can just use mouthwash every morning and night, other than brushing our teeth. Through that research, we can see which method of cleaning our mouth is more effective and why it is.
