In this project my goal was to figure out the effects that coffee, tea, and baking soda do to teeth. I chose those 3 items because coffee and tea are the most common drinks that people consume on a daily basis and baking soda happens to be the most popular DIY method of teeth whiting. Since science is about questioning and experimenting I decided to do so. I wanted precise information and this experiment took a total of 8 days before the coffee and tea started to get moldy and gross.

Here is day one. The rock on the far left is a white marble rock that had a ruff, dusty texture to it. My goal for this rock was to see if the baking soda would disintegrate because if you look on my pervious post baking soda cleans off surfaces.
The rock in the middle is a clear marble and sort of reminded me of perfect white teeth so I decided to use that as a substitute for a tooth.
Finally the last rock is almost as clear as the coffee rock but has a little bit of dark shades on it. Its ok though. That rock is going to be tested on cranberry apple tea.

On day three I noticed a significant change to the rocks. The baking soda rock already looked way much clearer. It started to even look a little transparent. I noticed that the powder, rust,an dust began to come off.
For the coffee rock, it already started to darken and stain right away and obviously on day 3 it has gotten even worse. The clearness of that rock began to darken and get cloudier and cloudier. :(
The tea rock began to stain a little bit red but it looked like it was water soluble which means that the water would probably be able to remove that redness that was starting to stain the rock.

On the last day I noticed how different and gross the rocks turned out. The baking soda rock looked clearer than it started and eventually did turn transparent.
The coffee rock was brown, cloudy, and dirty looking when it started as a beautiful clear little rock.
The tea rock turned red on some of the edges but was still almost the same color on other parts of the rock.

So you might be wondering why the tea was able to only stain the edges but not the rest of the rock like the coffee did? Well, teeth have microscopic pits and ridges (like rocks) that easily collect things like food and heavy colored drinks. Rocks have something similar because like teeth rocks also have different edges and bumps all over which is why the redness of the tea mostly stained in the edges of the rock. The beautiful, clear, crystal rock that was put in the coffee also had lots of bumps EVERYWHERE, which was a reason as to why it stained to quickly and badly. And finally the baking soda rock was able to get nice and shinny thanks for the baking soda.
This project turned out just as I thought it would. All my results were expected except for the tea. I did not think that the tea would be able to stain because it is basically just plants or leafs soaked into water. Obviously its a safety hazard to keep something that is molding so I had to throw it put but, if I could keep this experiment going I would because I would want to keep those rocks soaking and put them to the test to see if the baking soda would be able remove the stains and how long it would take.
From this project I take away a lot of new knowledge about coffee and teeth whiting because I am a coffee addict. But now that I know all the damage that coffee can cause your teeth and health, I will slow it down with all the coffee.
