Research Topic: Are toothbrushes really clean?
Research Summary:
RJS research examined the cleanliness of everyday toothbrushes using a scanning electron microscope. The study found that while no harmful contaminants were present after a month of use, the effectiveness of the toothbrush was compromised due to the wear and tear of the bristles. This research highlights the importance of replacing your toothbrush head regularly—ideally, once a month—to ensure your teeth are getting the best possible care.
