Even Cher was ragging on Miley Cyrus' bad breath following the former Disney star's infamous performance at the MTV VMAs.Cleaning up that white-coated tongue would not have redeemed Cyrus' booty-shaking and blurred thighs, but perhaps it would've helped. In an interview with USA Today to promote her new album, Cher spoke her mind. "I'm not old-fashioned. She could have come out naked, and if she'd just rocked house, I would have said, 'You go, girl.' It just wasn't done well. She can't dance, her body looked like hell, the song wasn't great, one cheek was hanging out. And, chick, don't stick out your tongue if it's coated." Cher is no stranger to scandalous outfits: in fact, some may argue she helped pioneer them. That only made her remarks even more poignant. The all-star diva has had her fair share of dental work in the past, too. At age 30, she went to the dentist for a routine teeth cleaning, and noticed some teeth shifting. Later she underwent procedures to correct her smile. And now look at her! She has a great teeth and in the 50 years she's been at it, not one picture quite as smelly as Miley's has surfaced. She knows a thing or two about oral health. Through hundreds of interviews and performances, Cher kept it fresh. So how did she manage? Here are some of the best ways to maintain a clean mouth during a high endurance activity or performance: 1. Stay hydrated. Halitosis often is the result of lack of moisture in the mouth. When saliva production is low, bacteria is allowed to form, which is why your groupies may be running away from you after you walk off stage. Water washes down the bad bacteria and helps stimulate saliva flow. Keep a bottle of H2O with you for in between songs, during a hard workout or after a run. 2. Avoid mouthwash that contains alcohol. You might wink at yourself in the mirror as you're swishing around rinse, thinking it's the ticket to long-lasting minty breath. But did you know that many mouthwashes actually dry out your mouth, leaving you with worse-smelling breath than before? Alcohol is the culprit, so make sure you pick up some without it, a.k.a. the best mouthwash for bad breath. 3. Brush twice a day, floss once a day. Let's rephrase, because normally we don't listen to the second half: Floss! Floss! Floss! The thread can dislodge food particles from in between teeth - places that your toothbrush can't reach. Also, once a day doesn't mean once a month. Consistency is key, so get into a habit of it like you do for brushing and you'll be golden! Do you really want yesterday's hamburger meat caught between your molars? That's what we thought. 4. Chew gum with xylitol. It'll increase saliva flow to flush out bacteria and food. Keep a pack or two in your back pocket or guitar case when the time arrives. Chewing after meals also proves effective at combating stink. Stress from high-pressure performances can leave your mouth feeling like the Sahara, so be sure you take a deep breath and know that you're going to rock the house. After all, doctors have found a link between a healthy mouth and a healthy heart. As our heart rates jump when stressed, our dental health gets progressively worse. According to a study published simultaneously in the Journal of Periodontology and the American Journal of Cardiology, unsightly gums has been shown as a risk factor for coronary artery disease. Now, just breathe easy, and you'll do great!
