The Scientific Method
1. Choose a problem.
(What do you want to explore? Ask a question about it.) * Choose something that interests you. * Choose something that you don't know the answer to. * Choose something you can work with.
Which soda decays fallen out teeth the most?
2. Research the problem.
(How can you find the answer to your question?) * Look in books. * Get advice. * Make observations.

If you take your teeth, put them in a glass, pour soda over them and let them stand for days (or was it weeks...?), it will dissolve away the teeth. I saw a science project on it. Some kid actually acquired some used teeth and did the experiment for a science fair. I believe the clear drinks were the worst, but I don't really

When they eat those foods, the bacteria create an acid that attacks tooth enamel and causes decay. The acids that cause tooth demineralization (cavity formation) are produced by specific types of bacteria (mutans streptococci and lactobacilli) that live in dental plaque.
These bacteria are living organisms just like we are. When we consume foods and beverages, we create waste products. Bacteria do the same thing. The bacteria that cause tooth decay utilize sugars (glucose, sucrose, fructose, lactose, or cooked starches) as their food source. The waste products created from digesting these sugars are the acids (especially lactic acid) that cause the demineralization of tooth enamel and dentin.
Since the bacteria that live in our mouth eat when we do, as we ingest foods which contain sugars (such as soda, candy, milk, and even fruits and vegetables) these bacteria get a meal too. And within minutes they start producing the acids that cause tooth decay. Bacteria that are exposed to sugars or carbohydrates can make acid, which attacks the crystal-like substance in the tooth's outer surface. This process is known as demineralization. The first sign of this is a chalky white spot. Acid formation, and hence tooth demineralization, begins within minutes of the bacteria receiving a sugary meal. It can take up to several hours for saliva to penetrate the layer of dental plaque and neutralize these acids. At this stage, the decay process can be reversed. Using
