Abstract
Toothbrushes are used daily and can collect bacteria from both the mouth and the surrounding environment. If toothbrushes are not properly cleaned and stored, bacterial growth may increase, which could impact oral hygiene. Understanding which cleaning and storage methods are most effective can help people improve everyday health habits. This project will evaluate common household practices to determine which methods best reduce bacterial contamination.
