You Should Be Using Mouthwash Way More Often Than You Do By Jasmine Gomez, Alexis Jones of Women's Health | TBH, mouthwash isn't the most fun o*** hygiene accessory. The annoying burning sensation that occurs during swishing can be kind of uncomfortable. But you have to admit that the way it leaves your breath fresh and your mouth clean feels sooo much better than brushing alone. In addition to brushing twice a day and flossing on a regular basis, mouthwash can be a game-changing supplement to your daily teeth cleaning, according to Ruchi Sahota, DDS, and American Dental Association (ADA) dentist. Gary Glassman, DDS, agrees."It is the perfect way to end off your o*** fitness routine each day and get that extra burst of protection," Glassman says.
