The Effects of Whitening Strips, Toothpaste, Mouthwash, and an Original Home Remedy on the Whiteness of Teeth
Having white teeth can boost confidence, promote health, and is a desired feature to have. It is extremely costly and may not always be worth this cost. However, if the most effective way to whiten teeth could be discovered, it would save time, money, and effort. The objective of this experiment was to determine whether Crest whitening toothpaste, Crest whitening mouthwash, Crest whitening strips or an original home remedy consisting of water, hydrogen peroxide, and baking soda, had the greatest effect on the whiteness of teeth.
There were four individual tests within this experiment. First, 120 tiles were dyed brown with Lipton tea. The tiles were then tested for the tiles for the toothpaste, mouthwash, strips, and home remedy. Each treatment had 30 trials performed. For the toothpaste and home remedy, the tiles were brushed. For the mouthwash, the tile was placed in a closed container and shook in order to simulate the swooshing of mouthwash around the mouth. The strips were placed on the tiles and left to sit just as they would be on human teeth. In order to interpret this data, six two-sample t tests were performed. In result, the toothpaste and home remedy had the greatest influence on the whitening of teeth. However, there was not a significant difference between the two. From this research, it is advised to purchase the Crest whitening toothpaste, or the original home remedy to have the greatest effect on the whiteness of teeth.
