I’ve frequently pondered the proper approach to this matter. In my upbringing, my mother insisted on brushing before eating in the morning and, naturally, before bedtime.

However, my girlfriend perceives this as unhygienic and has expressed disapproval on multiple occasions. What would be the recommended course of action regarding this matter?
