Drink green tea or coffee
A cup of tea after taking foods containing garlic or onion can reduce bad breath. You can take a cup of green tea immediately after eating a meal to prevent bad odor until you brush or floss. According to studies, people who use mouthwashes that contain green tea are less likely to experience bad breath. Due to their antiplaque properties, these mouthwashes are effective in killing accumulated plaque. Green tea can also be used to prevent the development of bacteria in the mouth.
According to research, consuming freeze-dried coffee or roasted coffee beans can reduce garlic breath. More research needs to be done to understand the effects of coffee on garlic breath.
