Effect of carbonated drinks on the erosion of tooth enamelFeatured science projectScience project video

Observation

It is observed that all the teeth immersed in the soft drinks lost some weight daily. The tooth that was immersed in Coca Cola lost the most weight and the tooth that was immersed in root beer exhibited the least erosion.
 

Soft drink Weight of tooth (grams)

Root Beer 2.35 2.35 2.34 2.33 2.33 2.32

The above results were then plotted onto a graph, as shown below.
