Answer: The eternal question! In theory, if you didn’t get up for a couple of cookies at night after your evening brushing, your teeth are clean in the morning and there are no soft dental deposits on them. The only thing there is after bedtime is the flaking epithelium from the inside of your lips, cheeks and tongue, which has not been washed away by enough saliva and water. This is the cause of bad breath in the morning. Therefore, I would recommend simply rinsing your mouth before breakfast and brushing your teeth after breakfast.
