Hollywood superstar Jennifer Lawrence is a highly paid actress, Oscar winner, successful producer and…merry prankster. She's the latter, at least with co-star Liam Hemsworth: It seems Lawrence deliberately ate tuna fish, garlic or other malodorous foods right before their kissing scenes while filming The Hunger Games.

It was all in good fun, of course—and her punked co-star seemed to take it in good humor. In most situations, though, our mouth breath isn't something we take lightly. It can definitely be an unpleasant experience being on the receiving end of halitosis (bad breath). And when we're worried about our own breath, it can cause us to be timid and self-conscious around others.

So, here's what you can do if you're concerned about bad breath (unless you're trying to prank your co-star!).

Brush and floss daily. Bad breath often stems from leftover food particles that form a film on teeth called dental plaque. Add in bacteria, which thrive in plaque, and you have the makings for smelly breath. Thorough brushing and flossing can clear away plaque and the potential breath smell. You should also clean your dentures daily if you wear them to avoid similar breath issues.

Scrape your tongue. Some people can build up a bacterial coating on the back surface of the tongue. This coating may then emit volatile sulfur compounds (VSCs) that give breath that distinct rotten egg smell. You can remove this coating by brushing the tongue surface with your toothbrush or using a tongue scraper (we can show you how).

See your dentist. Some cases of chronic bad breath could be related to oral problems like tooth decay, gum disease or broken dental work. Treating these could help curb your bad breath, as can removing the third molars (wisdom teeth) that are prone to trapped food debris. It's also possible for bad breath to be a symptom of a systemic condition like diabetes that may require medical treatment.

Quit smoking. Tobacco can leave your breath smelly all on its own. But a smoking habit could also dry your mouth, creating the optimum conditions for bacteria to multiply. Besides increasing your disease risk, this can also contribute to chronic bad breath. Better breath is just one of the many benefits of quitting the habit.

We didn't mention mouthrinses, mints or other popular ways to freshen breath. While these can help out in a pinch, they may cover up the real causes of halitosis. Following the above suggestions, especially dental visits to uncover and treat dental problems, could solve your breath problem for good.
