You use your mouth not just to eat and drink, but also to speak and express your thoughts about something. However, if you have bad breath, sharing your ideas seems constricted and talking to someone feels a bit uncomfortable.
Bad breath not only affects your confidence, but also your interaction with other people. Sometimes it can lead to shame and embarrassment, and all you can do is stop the conversation since the person you are talking to is getting restless while you talk. Fortunately, there are ways to control the unpleasant odour.
