In our science fair experiment we tested to see which type of tea would reduce oral bacteria the best. Our variables were oolong, white, black, herbal and green tea. After doing our experiment we found that green reduces oral bacteria the best because it contains a higher concentration of polyphenols than the other teas. We found that the other teas promoted the growth of bacteria. Oolong tea promoted the most bacteria followed by black, white and then herbal.
