Introduction/General Background
For my research project, I am researching if tea stains your teeth. The factors involved in this investigation will be researching egg shells, what they are made of, and their similarity to teeth.

The variables that I will be investigating will be types of tea, and the length of time the shells are spent in the tea. I am conducting this research project in order to discover if tea stains your teeth. If it does, then I would also like to find what kind of tea stains more and why.

While tea is often considered to be coffee’s gentler cousin, but when teeth are involved this may not be the case. Some black teas may actually stain teeth more than coffee. Similar to red wine, black teas tend to have a very high tannin content, which contributes to teeth staining.

Teeth are structures in the mouth that are individually squares or cubical-shaped with grooves intended for use in breaking down food for consumption. Teeth are naturally white or off-white in color, but build-up from foods and drinks such as coffee and tea over time can stain the white color and turn teeth yellow and discolored. Tea does stain your teeth, especially if you drink it on a regular basis. Tea contains tannic acid, which can create small pores in the enamel of your teeth.
