If nobody seems to want to hear about much of anything from you face-to-face, you may have a common problem that you should bring up with your dentist: bad breath.
Even worse than discovering your own bad breath is having someone else bring it up to you (as they slowly back away). But that's often what's needed to even know there's a problem in the first place. Once it's brought to your attention, however, trying to ignore the issue won't prevent others from noticing your stinky breath.
Bad breath is often caused by smelly foods you eat, such as onions or garlic, but in those cases, the problem passes once your body has fully broken down the problem-causing item. If your embarrassing breath isn't food-related, finding out what is causing it could pay dividends to your dental -- and overall -- health. For example, bad breath can be a warning sign of a worsening cavity or gum disease. The sooner these issues are addressed, the higher your odds will be of saving teeth or preventing further damage to your gums.
While poor dental health may be the culprit, bad breath can also be a result of non-mouth-related health conditions such as diabetes, problems with your liver or kidneys, and respiratory tract issues. You'll want to address breath issues with your dentist first, then consult your doctor if you still don't have answers.
