Does brushing your teeth help with a breathalyzer?

No, brushing your teeth doesn't help pass a breathalyzer; in fact, it can cause a false positive or higher reading because many toothpaste/mouthwash products contain alcohol, which lingers in the mouth and gets detected by the device, masking actual breath alcohol levels or even triggering a positive reading without drinking. Waiting 15-20 minutes after any oral activity (eating, brushing, mouthwash, smoking) before blowing into a device provides a more accurate result.

Police officers typically wait this period (observation period) before testing to avoid "mouth alcohol," ensuring a more accurate deep-lung air sample, so recent use right before a test is the main risk for an inaccurate result.
