Can I use Listerine instead of brushing my teeth before bed?

Mouthrinses and mouthwashes are not intended to replace tooth brushing. It is important to brush your teeth twice a day with a fluoride toothpaste. One of those times should be before going to bed to remove all food particles from teeth and prevent the length of attacks by food on teeth. Using a rinse after brushing can help freshen breath and prevent tooth decay.

Mouthwash is used to keep your breath smelling fresh and it is not an effective substitute for brushing your teeth at night. While some mouthwashes have added fluoride to fight cavities they do not work as well as daily brushing and flossing of your teeth, which removes food particles and plaque that can lead to tooth decay.

Listerine, as well as many other mouthwashes, are most effective after physically removing the plaque from the teeth and gums by brushing and flossing. It is the accumulation of plaque that causes cavities, gum disease, and bad breath. Plaque, the bacterial buildup on the teeth and gums, is very sticky and adheres to the teeth. It can be removed very easily with good brushing and flossing, however, a mouthwash will not remove plaque. It may temporarily make your mouth feel cleaner and your breath fresher, but that will be very shortlived without proper brushing and flossing.
