__**BACKGROUND INFO AND SOURCES**__
Studies shows that sports drinks cause more damage to the teeth than soft drinks. Four types of drinks that cause more tooth decay than soft drinks are bottled lemonade, sports drinks, energy drinks, and canned ice tea. The colas are the soft drinks that cause damage but not as much as bottled lemonade, sports drinks, energy drinks, and canned ice tea. The safest soft drink is root beer cause it doesn't have as much flavor additives than colas. It actually is the least amount of additions in flavor. []
 * According to J. Anthony von Fraunhofer:**

The bacteria in your mouth forms with the sugar in soda to make acid. Plus that acid and the extra acid in the soda attack your teeth. Each attack lasts 20 minutes, and it starts over with every drink you take of that soda. Pepsi and Coca-Cola are the top two sodas that have the most acidity in them. The number for those two are 4.5 and that is directly under battery acid which has 6 points of acidity. The soda that has the least amount is Barq's Root Beer which has an amount of 2.4 acidity. On top of that, the soda that has the most sugar is the Minute Made Grape Soda, which has 11.9 teaspoons of sugar. When the cavities start to form that means that the tooth enamel is damaged. http://www.msdh.state.ms.us/msdhsite/_static/43,2809,151.html

Studies say that the amount of drinks that Americans consume, that 27% is soda. The amount of soft drinks that 12-19 year old people consumed per day in 1977 is 16 ounces. Then those same ages doubled the amount of consumption by 1996. 1970 is when there were 22.2 gallons of Coca Cola consumed per person and by 1996 that amount had gotten to 44 gallons per American each year. It then increased up to 56 gallons per person in 1999, that meant that around 14 billion gallons of soda were consumed in the United States. []

__**Procedure:**__
Step 1: Get a full can of Pepsi, Mountain Dew, and Fanta Grape Soda. Step 2: Next get three teeth from the dentist. Step 3: Take the teeth and clean them with a tooth brush and tooth paste. Step 4: When the teeth are clean, place each one in a bowl and fill the bowl up to just above each tooth. Step 5: Wait for 5 days and collect results.

__**Materials:**__

 * 1) Pepsi
 * 2) Fanta Grape Soda
 * 3) Mountain Dew
 * 4) 4 teeth
 * 5) Tooth Brush
 * 6) Tooth Paste
 * 7) 4 bowls
 * 8) water

**__Data & Results__**
The three teeth that were put into soda were white and two of them were canine teeth, the other was a molar. The tooth that went into the water was a molar and it was a cleaned white tooth. At the end of the first day, the tooth in the grape soda had already turned really brown and it seemed to have rotted. The tooth in the Mountain Dew looked like it sucked in some of the soda and looked like it was starting to turn spherical. The tooth in the Pepsi looked like it decayed a tiny bit and a little bit rotten. The tooth in the water shows the way that the teeth would look like without the soda. On day two, there was no change to any of the teeth. There wasn't a change on the third day, the fourth day, or even the fifth day. All I saw for three days was the the water in every liquid was being drained and only a little bit remained.

**__Conclusion__**
My question was "What type of soda will decay teeth the most?" and the sodas that I used in the experiment were grape soda, pepsi, and mountain dew. My hypothesis was "I think that Pepsi will decay teeth the most." and I thought Pepsi was going to decay the teeth the most because of the data that I collected from a website. At the end of the experiment I found out that my hypothesis was correct. I took a look at the pictures of the teeth and I noticed that the Pepsi decayed the tooth, the Grape Soda rotted the tooth and the Mountain Dew just ate the tooth away. I also noticed that the teeth sucked up all the water in the sodas. The liquid that was left was the syrup in the soda and it was so gross.
