Occasional bad breath after coffee or garlic is normal and passes. Persistent bad breath, the kind that returns day after day despite brushing, is different: it almost always points to something inside the mouth that can be treated.<\/p>\r\n\r\n  <p>The reassuring part is that once the cause is found, it can usually be resolved at the source rather than masked. This guide explains where persistent bad breath actually comes from, which causes can be handled at home, which need a dentist, and what treatment involves \u2014 so the problem is solved rather than covered up with another mint.<\/p>\r\n\r\n  <hr class=\"da-divider\">\r\n\r\n  <!-- WHERE IT COMES FROM -->\r\n  <div id=\"ez-toc-container\" class=\"ez-toc-v2_0_74 counter-hierarchy ez-toc-counter

Daily tongue cleaning, flossing, and \u2014 if it persists \u2014 a dental check-up address what brushing alone cannot.\r\n      <\/div>\r\n    <\/div>\r\n\r\n    <div class=\"da-faq-item\">\r\n      <button class=\"da-faq-question\" onclick=\"daToggleBB(this)\">\r\n        Can bad breath be a sign of gum disease?\r\n        <span class=\"da-faq-icon\">+<\/span>\r\n      <\/button>\r\n      <div class=\"da-faq-answer\">\r\n        Yes. Persistent bad breath is one of the most common early signs of gum disease (periodontitis), because bacteria trapped in gum pockets produce a constant odour. Since untreated gum disease can lead to tooth loss, lasting bad breath is worth having examined.\r\n      <\/div>\r\n    <\/div>\r\n\r\n    <div class=\"da-faq-item\">\r\n      <button class=\"da-faq-question\" onclick=\"daToggleBB(this)\">\r\n        Does chewing gum get rid of bad breath?\r\n        <span class=\"da-faq-icon\">+<\/span>\r\n      <\/button>\r\n      <div class=\"da-faq-answer\">\r\n        Sugar-free gum containing xylitol can help temporarily by stimulating saliva and reducing bacteria, which freshens breath for a while.

Alcohol-based rinses can even worsen bad breath by drying the mouth. Mouthwash is a helper, not a cure.\r\n      <\/div>\r\n    <\/div>\r\n\r\n    <div class=\"da-faq-item\">\r\n      <button class=\"da-faq-question\" onclick=\"daToggleBB(this)\">\r\n        How is chronic bad breath treated at a dental clinic?\r\n        <span class=\"da-faq-icon\">+<\/span>\r\n      <\/button>\r\n      <div class=\"da-faq-answer\">\r\n        The cause is treated rather than the smell: a professional cleaning to remove tartar, treatment of any gum disease, and repair of decay or failing crowns, bridges, or dentures.
