We as the people have always relied on breath
fresheners to relieve our common problem of bad breath, but can we ask, does
it really work? The factors leading up to bad breath are quite simple, food
and bad oral hygiene. When upon eating food, it's absorbed within the
bloodstream, where it is carried into the lungs and then ejected. The
approach of sanitizing your mouth will only eliminate the odor for a temporary
amount of time, as the odor will eventually die off when the body disperses
the food. Another common factor that contributes to bad breath is Xerostomia,
also known as dry mouth. Your mouth has a tendency to dry out over night
during a night’s sleep or over a long speech such as a regular conversation.
Mostly bacteria on the tongue and gums are also a leading cause in bad
breath. As a human grows older, their gums create pockets, which is a
convenience place for bacteria to generate. The pocket basically houses the
bacteria in a place out of the reach of toothbrushes and even to mouth wash.
Basically, natural bodily functions and human tendencies are factors in which
causes the common problem of everyday bad breath, but still how can people
Since the real question is, which breath
freshener will reduce the most oral bacteria? The scientist must test a
series of breath fresheners to display which ones are most productive. Due to
scientific researching, the scientist's hypothesize that the outcome of this
experiment is that Listerine Mouth Strips will work the best because it kills
99.9% of odor-causing bacteria in 30 seconds. The purpose of this experiment
is to show which breath fresheners work the best from different competitive name
brands that people use to help maintain good breath. This will also display
what people have been wasting their money on and what people should spend
money on. The Constants are the temperature of 98.6 degrees Fahrenheit at
which the experiment undertaken, the time of which all Petri dishes were
placed, and the incubator used. The Independent Variable is which type of
breath fresheners that were used, and the dependent variables are the ring of
circumference that is from which the bacterium doesn’t grow.
The experiment was quite simple, gather all
the elements that are needed, which is a loaned incubator along with ten
different pea tree dishes, ten different types of breath fresheners, 10
Q-tips, and 5 days in allotted time. Once gathering all materials, keep to
the following procedures:
" Take one Q-tip and swab your mouth
" Take the Q-tip out of your mouth, and
wipe it in a vertical motion and then a horizontal motion on the Petri dish.
" Dispose of each Q-tip, do not re-use.
" Place the desired breath freshener in the
middle of the Petri dish
" And repeat the same process for the rest
of the other Petri dishes
" Then once everything's done, place all
Petri dishes inside of incubator for 5 days at 98.6 degrees
" After 5 days, take all 10 Petri dishes
out of the incubator, and measure the circle of circumference of which the
bacteria did not grow on.
" Record Data for that one particular Petri
dish, and repeat for all 10 other Petri dish.
These breath fresheners that were used
consisted of: Listerine mouth wash, Listerine mouth strips, Altoids, Certs,
Tic Tacs, Icebreakers, Winterfresh, X-it, Nu breath, and Sweet Breath. It was
necessary to conduct the incubation period under the normal oral temperature
of 98.6 degrees for the experiment to be most effective as possible. After
five days of unclosed incubation under oral temperature, the odor was
unbearable. The stench was very concentrated with different communities of
The diameter of the circles left in the petri
dishes was measured. The ranges of diameters were from attracting bacteria to
13mm. It was surprising that some breath fresheners could either attract more
oral bacteria, or relieve no odor at all. The average range of all the
diameters was 4.6.
Listerene Mouth Wash 13mm
Listerine Mouth Strip 1mm x 1mm
Tic Tacs Attract oral bacteria
Ice Breakers Capsules 4mm
Nu Breath 4mm
Sweet Breath 7mm
The results showed that Listerine Mouth wash
covered the most area in sanitizing oral bacteria. Ironically, Tic Tacs
attract oral bacteria and Winterfresh just doesn't help whatsoever. A common
buy for the relief of bad breath is the famous British Altoids. The
experiment shows that Altoids can be somewhat reliable. Sweet Breath is also
an unknown reliable freshener. Next to the highest freshener in diameter is
x-it. This small capsule is half the size of an Altoids, but works twice as
The scientist's hypothesis was rejected. The
Listerine mouth strips' ring of circumference had a diameter of 1mm x 1mm.
The freshener with the largest ring of circumference was The Listerine
Mouthwash. The mouthwash had a circumference of 13mm. This shows that
Listerine Mouthwash is the best way to go. Using this daily and after meals
will help reduce the common problem of bad breath.
